Broaching is a machining process with a special designed multi point cutting tool called broach. This process is widely used in automobile industries for machining various holes, key ways, gears etc. Broaching operation involves linear motion of tool about the work piece. This movement of tool removes material from work piece and provides a desired shape.

 

Broaching tools involve a large number of progressive teeth which make this operation different from other process. Each tooth takes off a successive layer of the material which removes large material in a single pass.

 

One of the major advantages of using this operation in various industries is its ability to give better surface finish and good accuracy with mass production rate. In this article we will discuss about broaching operation Principle, tools, types, advantages and disadvantages.

 

Broaching Process:

 

Principle and Operation:

As we discussed the metal removal process in broaching operation is similar to shaping process except it uses a series of progressive teeth which can cut more material in a single pass. Shaping process requires number of strokes to cut required width of work piece in which each stroke removes a thin layer of metal. This process needs more time which is not beneficial. This limitation is taken off by broaching process by providing a successive series of cutting edges on a rod or bar type cutter.

 

Machine Tool:

Broaching uses a multi-point cutting tool to have a series of progressive cutting teeth. This tool like broach shaper cutter should have high strength, hardness, cutting speed and wear resistance properties. It is made by high strength tooling material like high speed steel, cemented carbide etc.  This tool is mounted on broaching machine.

 

Broaching machine is simple in construction. It is used to provide linear motion of the tool and hold the work piece at stationary position. The tool movement can be either vertically or horizontally. According to it, these machines can be classified into two type vertical machine and horizontal machine. Horizontal machine is mostly used for internal machining and vertical machines are used for external and surface machining.

 

Types:

Broaching can be classified into following types:

 

  • Internal Broaching:

Internal broaching is mainly used to enlarge holes. This process generally uses pull type broach but for lighter work piece, it sometime uses push type broach.

 

  • External Broaching:

External broaching is mainly used to flattening of a surface, machining key ways, slots, grooves on outer part of an object such as shaft etc. This process is also used for gear manufacturing process.

 

  • Pull Types Broaching:

A broach which is subjected to tensile force during machining, called pull broach and the type of broaching operation by pull broach is known as pull broaching. This operation prevents misalignment and buckling. The pull broach is usually made in single piece and used for internal broaching.

 

  • Push Type Broaching:

Push type broach is usually subjected to compression force during machining. These are made shorter compare to pull type broach and mostly used for external broaching.

 

  • Ordinary Cut Broaching:

Ordinary cut broaching uses ordinary broach in which teeth increases in height gradually from tooth to tooth along length of broach.

 

  • Progressive Cut Broaching:

In progressive cut broaching teeth increase in width instead of height along length of the broach.

 

  • Solid, Section and Modular Broaching:

Solid broaches are made in single piece which are mostly used for internal broaching. Sectional broaches are made in section by assembling various section of broach. Module broaches are made by various modules assembled in a single unit. It is used for external broaching.

 

Advantages and Disadvantages:

 

Advantages:                                                                             

  • High production rate because whole amount of metal is removed in single stroke.
  • High surface finish and better accuracy.
  • Broaching can be used for both internal and external machining.
  • Broaching machines are simple in design and construction.
  • It can be used for mass production.

 

Disadvantages:

  • High tool cost.
  • This process needs a special design tool for each process.
  • This is not suitable for small batch production.
  • It is only suitable for machining holes and flat surfaces.

 

This is all about broaching operation, tools, types, advantages and disadvantages.

While the Metal Spinning industry is ploughing its way through making hundreds and thousands of machine spun products, you have to wonder what the advantages are and disadvantages of CNC (Computer Numerical Control) machines compared to manually operated center Lathes?

 

CNC machines are very expensive to buy; however as the years move on the cost is decreasing due to the development of more efficient CNC models (and software). Manual lathes are cheaper to buy and require less setting up whereas CNC machines require you to either have somebody install and set it up or you can do this process yourself.

 

Size matters! If you are an SME (small to medium size enterprise) you may not have the space available for a CNC machine. Most models take up more than space then a manual lathe. CNC’s can contain and collect unwanted debris compared to manual lathes where the debris fall to the floor, making it a trip hazard and generally making the workshop look untidy.

 

CNC machines can be operated by one person. That one person can attend to more than one machine due to the machine producing all the work, with only a need to either change the tooling, replace a finished product with a new piece of material or to collect and dispose of material debris. Little training is needed for this one person to work the CNC machine. This is declining the need for skilled manual lathe workers, putting people out of work, and threatening the industry with less people being taught in the art of manual machinery type jobs.

 

CNC machining is reliably 99.99% accurate, and can produce products four times quicker than on a manual lathe. The other .1% is when the product dimensions can sometimes be off by up to 0.5mm, often this is due to the type of material, the temperature of the environment or the tooling being faulty; however this is a very rare occurrence. The machine is designed and programmed in such a manner that thousands of products with the same dimensions can be manufactured with complete accuracy and just with a single command. Even though the advantage to a CNC machine is that it can produce products with speed and accuracy, there are some jobs it can’t do, that a skilled worker can achieve on a manual lathe. But the downside to this is that human error can’t product a perfect product every time.

 

The CNC machine can be operated 24 hours a day, all year round, only stopping for maintenances. At the same time, updating the software can improve performance and speed. Depending on the type and size of job the CNC is required to do; renewing the tooling can be both cheap and expensive.

 

Prototypes are often required by the client before making the actual product. This could be to make sure the product has been designed correctly and can be made to the exact specifications. Finding a fault in the design early in the product life cycle will mean the design can be altered and will save time and money. The CNC machine does have the software that can simulate prototypes, therefore eliminating the need to use the CNC machine to make a physical prototype. This is another way to save money and time.

 

There may be more positives for the use of a CNC machine, but it would be wise if a SME wants to invest in a CNC machine, to always keep the manual lathe process within the company and not always rely on CNC machines. Although they allow for a much faster and accurate production line and eventually it will pay for itself, there is always the possibility that It could break down, so a backup of manual lathes can at least keep up with the constant demand of work should the need arise.

 

Shun Chuan is a professional lathes manufacturer who specialize in producing CNC lathe and manual lathe for more than 15 years. They insist to manufacture the efficiently and high-performance lathe machines for clients. Also, Shun Chuan dedicates in research and development to innovate lathes to meet the clients’ demands in top standard.

Once this system is developed, it must certainly be loaded into the CNC control. Although the setup person could type this system right into the control, this might be like using the CNC machine as a very costly typewriter. If the CNC program is developed with the aid of a CAM system, then it has already been in the form of a text file. If this system is written manually, it may be typed into any computer employing a common word processor (though most companies make use of a special CNC text editor because of this purpose). In any event, this system is in the form of a text file that can be transferred right into the CNC machine. A distributive numerical control (DNC) system is employed for this purpose.

 

A DNC system is only a PC that’s networked with one or more CNC machines. Until only recently, rather crude serial communications protocol (RS-232c) needed to be employed for transferring programs. Newer controls do have more current communications capabilities and may be networked in more conventional ways (Ethernet, etc.). Aside from methods, the CNC program must obviously be loaded into the CNC machine before it may be run.

 

Types of CNC Machines

 

As mentioned, CNC has touched virtually every facet of manufacturing. Many machining processes have been improved and enhanced through the use of CNC. Let’s look at some of the specific fields and place the focus on the manufacturing processes enhanced by CNC machine usage.

 

In The Metal Removal Industry:

 

Machining processes that have traditionally been done on conventional machine tools which can be possible (and sometimes improved) with CNC machining centers include a myriad of milling (face milling, contour milling, slot milling, etc.), drilling, tapping, reaming, boring, and counter boring.

 

In similar fashion, a myriad of turning operations like facing, boring, turning, grooving, knurling, and threading are done on CNC turning centers.

 

You will find a myriad of special “off-shoots” of these two machine types including CNC milling machines, CNC drill and tap centers, and CNC lathes.

 

Grinding operations of all types like outside diameter (OD) grinding and internal diameter (ID) grinding are also being done on CNC grinders. CNC has even opened a brand new technology as it pertains to grinding. Contour grinding (grinding a contour in a similar fashion to turning), which was previously infeasible as a result of technology constraints is currently possible (almost commonplace) with CNC grinders.

 

In The Metal Fabrication Industry:

 

In manufacturing terms, fabrication commonly identifies operations which can be performed on relatively thin plates. Consider a steel filing cabinet. All the primary components are made of steel sheets. These sheets are sheared to size, holes are punched in appropriate places, and the sheets are bent (formed) to their final shapes. Again, operations commonly called fabrication operations include shearing, flame or plasma cutting, punching, laser cutting, forming, and welding. Truly, CNC is heavily involved in virtually every facet of fabrication.

 

CNC back gauges are commonly used with shearing machines to control the length of the plate being sheared. CNC lasers and CNC plasma cutters are also used to create plates to their final shapes. CNC turret punch presses hold a variety of punch-and-die combinations and punch holes in most shapes and sizes through plates. CNC press brakes are used to bend the plates within their final shapes.

 

In The Electrical Discharge Machining Industry:

 

Electrical discharge machining (EDM) is the procedure of removing metal through the use of electrical sparks which burn away the metal. CNC EDM comes in two forms, vertical EDM and Wire EDM. Vertical EDM requires the use of an electrode (commonly machined on a CNC machining center) that’s of the form of the cavity to be machined into the task piece. Picture the form of a plastic bottle that must definitely be machined in to a mold. Wire EDM is commonly used to create punch and die combinations for dies sets found in the fabrication industry. EDM is among the lesser known CNC operations because it is so closely related to making tooling used with other manufacturing processes.

 

In The Woodworking Industry

 

As in the metal removal industry, CNC machines are heavily found in woodworking shops. Operations include routing (similar to milling) and drilling. Many woodworking machining centers are available that can hold several tools and perform several operations on the workpiece being machined.

 

Other Forms of CNC Machines

 

Many types of lettering and engraving systems use CNC technology. Waterjet machining runs on the high pressure water jet stream to cut through plates of material. CNC is even found in the manufacturing of many electrical components. For example, there are CNC coil winders, and CNC terminal location and soldering machines.

 

SIGMA CNC Technology Machinery Co., Ltd. can offer you a variety of CNC machining centers including CNC high speed double column machining center, CNC double column 5-face machining center, and CNC moving column horizontal machining center etc. If you want to know more specification and features about machining center, welcome to visit SIGMA’s website to obtain further details you need.

Companies in the carbide cutting tool industry are under pressure to provide precision tools according to the specifications laid out. Getting a carbide cutting tool is not enough, quality and precision play a crucial role.

 

End-mills are the primary precision tool used by vertical mills. This is a kind of milling cutter which is usually used as a cutting tool in industrial milling applications. It is like a drill bit but varies in terms of geometry, application and manufacture. A drill bit can only cut in the axial direction while a milling bit can cut in all directions, though very few cannot cut axially. Solid Carbide End Mills can be found in a variety of industries, including medical, aerospace, power generation, mold & die and general machining. The quality and style also vary. The most common ones are the 2-flute, 4-flute, 6-flute end mils. You can buy them individually in sets or individually.

 

It is an industrial must that high performance carbide mills be designed with accuracy. Your carbide cutting tool will continue to perform consistently throughout, lasting longer, which helps to keep your quality production line of products on schedule. The success of projects depends on the consistency and reliability of the machines being used. Long tool life increases machine up-time, which provides greater production capacity without investment in additional equipment. The 6 flute carbide-mill is for Radial relief with a thicker carbide core that provides higher strength. This is an excellent choice for nickel/high temp alloys, titanium, carbon steels and stainless steel.

 

End mills provide significant savings for industries in several ways. Almost two to three times faster cutting speed as compared to conventional tools. The quality of the work piece will speak for itself. They also offer excellent dimension control. The result is consistent finishes resulting in minimized scrap rates. Two important properties that have to be considered to determine the efficiency of cutting tools include abrasion resistance and toughness.

 

High performance end mills have been specially engineered for the roughing and finishing of steels and exotic materials. They are made from the highest quality fine grain carbide available, these end mills work where others fail. They have been engineered with a variable pitch design for increasing depths of cut and increased feed rates with reduced chatter.

 

It is increasingly common for traditional solid carbide mills to be replaced by more cost-effective inserted cutting tools. While purchasing an end mill, make sure you check the material, level of hardness, heat treatment, quality and finish.

 

Earth-Chain Enterprise Co., Ltd. is a professional manufacturer of magnetic tools. They also provide end mills and drill grinders for clients.

Electrical Discharge Machining (EDM) has been removing metal by spark erosion for more than half a century—with sinker (ram/Elox-) style EDMing for molds and wire EDM for precision parts cutting, especially dies. A third type, EDM drilling, has emerged for precision holemaking in the smallest sizes, going beyond its use initially as an EDM “popper” for starting holes in hard metals.

 

Today, there is no end in sight for precision machining applications like small holemaking for which EDM drilling in combination with other processes is being used. Originally an alternative to machining processes like turning and milling, EDM is often used in combination with other advanced machining processes. It has flourished as technology embraced advances in digital generators for more precise spark control and software that draws upon a legacy of machining data for more efficient production.

 

EDM Drilling Small, Tight Tolerance Holes

 

Fast hole EDM drilling machines can be used to efficiently manufacture small, tight tolerance holes, for example, in medical parts that require the insertion of suture material and guide wires. Recent enhancements in this technology include controller and power supply upgrades. “Software and hardware upgrades to the controller and EDM power supply improve drilling speed and stability, while reducing electrode usage and improving metallurgical recast issues,” said Steve Bond, sales manager- EDM Products, Methods Machine Tools Inc. (Sudbury, MA).

 

Wire EDM Designed for Ease of Use, Low Cost of Operation

 

Advances in wire EDM technology focus on programming and software is designed for ease of use, as well as accuracy and quality of finish. Such is the case with two new large scale wire EDM machines from Makino Inc. (Auburn Hills, MI). The U3 and U6 wire EDMs feature new HyperCut technology and Hyper-i control that make is easy for even novice operators to program and produce the most complex parts in competitive cycle times and high degrees of accuracy and finish, regardless of the condition or application.

 

By the way, when mention of EDM machine, I’ll recommend you to visit the website of OCEAN Technologies Co., Ltd. and EXCETEK Technologies Co., Ltd. Both of two companies are professional and reliable electric discharge machines manufacturer in the industry.

Band saws come in many different shapes and sizes, each with their own unique selling points and purpose. The band saw is regarded as one of the most versatile power tools on the market according to Popular Woodworking Magazine, renowned for its ability to cut through just about any material, however, it is not often the first machine purchased for a workshop.

 

The material you’re working with and type of project you’re completing will determine which of the different types of band saws to use. Vertical, horizontal, timber, and metal, cover just some of the band saws available.

 

This article will take you through some of the different types of band saws and some of their common uses, as well as a general guide to band saw safety that can apply to any type of this powerful tool.

 

Metal Band Saw

Of all the different types of band saw, a metal band saw is the ideal power tool for jobs that require you to cut through tough metal.

 

Metal cutting band saws generally fall into two categories, the vertical band saw and the horizontal band saw. The horizontal metal band saw is generally used to cut stock down to size, whereas the vertical one can be used for more intricate jobs such as filing, polishing, and contour cutting.

 

They do require some extra maintenance though and generally have some additional features built in. A coolant that keeps the blades lubricated and cool, as well as brushes or brushwheels that prevent metal chips from being caught in the blade, are both common to find on these types of band saws.

 

Unlike other saws, band saws have the unique ability to cut through a range of materials other than just wood, making them a popular tool in most workshops.

 

Wood Band Saw

A wood band saw is a popular choice among amateur and professional woodworkers. Often compared with the table saw as one of the most important power tools in carpentry, the wood band saw is a truly versatile machine.

 

While smaller stationary band saws are used in workshops, timber mills also operate large scale band saws for ripping lumber. The band saw has the unique ability to work with timber that’s of a larger diameter, and because they have a smaller kerf, or cut size, there is less of the quality timber wasted.

 

Wood band saws operate the same as any band saw, with the blades located on a continuous loop of metal teeth which perform succinct cuts through the timber.

 

Horizontal Band Saw

The horizontal band saw is one of the broader categories of band saw, favored by both amateur and professional carpenters. These types of band saws are useful for cutting longer materials down to size, however, not so ideal for producing complicated shapes or curved lines.

 

A horizontal band saw works by holding the material stationary while the band saw blade swings down through the cut. Once the cut is complete, the saw will automatically turn off with a switch trip to avoid potential injuries to the operator.

 

Some of the benefits of using a horizontal band saw include:

 

  • A quieter cut than most saws, making for a calmer workspace;
  • Extreme precision and accuracy when cutting straight lines;
  • The ability to set up your cut and then leave the machine to complete it, even turning off automatically once done;
  • Ability to cut wood, metal and plastics with ease;
  • No heat-affected zone after use, meaning safer operation with less risk of injury

 

Vertical Band Saw

A vertical band saw varies from its horizontal counterpart in how it cuts through the material. The saw itself doesn’t move, but rather the workpiece moves through the blade to create intricate cuts.

 

A vertical band saw is so versatile it can be used to create complicated shapes and lines that other types of band saws can’t compete with. As well as being adept at cutting complicated shapes, the vertical band saw can also perform precision cut straight lines, making it a great all-rounder power tool.

 

These saws have a superb cutting capacity and the ability to cut through materials fast, and with brush wheels installed they have safety measures in place to ensure chips don’t become stuck in its metal teeth.

 

Not only is the vertical band saw capable of cutting with ease, it also usually features a built in welder. The welder is useful for creating new blades or repairing old ones, and can even route the blade through the center of a part so that it can make interior cuts to the material.

 

Safety Guide

Although they’re often touted as one of the safest power tools around, you still need to be aware of the safety precautions for operating a band saw. A stationary band saw poses less of a threat than machines with a movable blade or saw which lowers their risk for injuries.

 

According to the Fine Woodworking Magazine, there are 12 cardinal rules for band saw safety that should be followed. These rules apply to all types of band saws and apply to working with any type of material, however, some styles may have extra rules regarding their safe operation.

 

  1. First and foremost, you should always consult the individual guidelines for your band saw as recommended by the manufacturer.
  2. Always ensure that fingers and other body parts are kept out of the path of the blade.
  3. When approaching the end of the cut, be sure to decrease the feed pressure.
  4. While the saw is in use always keep the wheel covers closed.
  5. Adjust the upper guide roughly quarter of an inch above your material before use.
  6. Always utilize the blade guard and keep it in place.
  7. Before changing blades, disconnect the band saw completely from its power source to avoid any accidental starts.
  8. As with any power tools, always wear eye protection while in the workshop.
  9. In the case of a broken or errant blade, ensure the machine has come to a complete stop before opening the wheel covers.
  10. If you have chips stuck in the throat, make sure you stop the saw before clearing the obstruction.
  11. To keep your fingers away from the blade, use push sticks that are stored in your miter slot.
  12. Always keep your workpiece in contact with the table at the exit point of the blade.

 

Conclusion

Not only is the band saw adept at making curvaceous cuts, but they can also perform precision cross cuts and rip lumber. If you have a quality band saw in your workshop you’ll already know how smooth their cuts can be, and performed with minimal effort.

 

If you’re looking for a band saw for your workshop, you’ll need to determine how much space you have available. There are some amazingly powerful and smaller bench top models that can still get the job done without taking up too much room.

The sinker EDM machining process uses electrodes that are electronically charged and configured to specific geometry to burn electrode geometry to metal components. The Sinker Electrical Discharge Machining process is a process that is commonly used in the production of molds and dies. It works by having two metal parts submerged in an insulating liquid connected to the current source which is then switched on and off automatically in relation to the parameters that are set by the controller. Electric tension is what is created between the parts when the current is on.

 

When brought together, the two parts of the metal heats up to a melting point; when the electrical tension is discharged and spark jumps across. Innumerable spark sprays gradually shape the desired form into the metal depending on the electrode shape. The Sinker EDM process is most suitable for those looking to minimize machining risks with accuracy and reliability. One of the major benefits of the process is the ability to produce shapes that are more complex without inducing stress onto the material. It doesn’t cut all the way through the material unless this is a requirement and thus it is a process that has a wider variety of applications including thin walls, blind cavities and cross sections. The efficient technology is great for injection molds and stamping dies and can be used to make the mirror surface too.

 

How mirror surfaces are done

 

Mirrors are smooth surfaces that have a shiny dark background that reflect well. Polished metal reflects extremely well and this is something that can be achieved by the sinker EDM machines. The common raw materials that are used in mirror making include glass, but because it is a poor reflector, it needs a metal layer on its surface to create an even surface with impressive reflection. Plastic substrate works as well as glass and it is commonly used in making mirror surfaces for children’s toys. Injection molding is what is applied to create the desired shape, whether circular or flat, transparent or opaque. Generally, the base materials need to be coated to make a mirror and this is where the sinker EDM comes in handy.

 

  • First, the outline of the blank material is made to suit the application. The final shape desired is what determines the cutting method. The cutting is done before the metal coating takes place.

 

  • Blanks are then placed in optical grinding machines and gritty liquid that is the grinding compound is spread over the blanks as they rub against curved surfaces.

 

  • After the polishing of the surface into a smooth finish, a coating with the desired reflective material is then done. The Sinker EDM is used to heat the metals so they can vaporize and get deposited on the surface. Precision is needed to ensure that the timing and temperature are just right in getting the right thickness and uniformity is achieved in the end.

 

  • Masks and metal stencils can be applied to the surface to create patterns and dielectric coatings can also similarly be applied as reflective layers or protective layers over the metal ones. A number of evaporation steps maybe necessary for multiple layer coating before the mirror is mounted on the base and packed in shock resistant packages.
