Overview and Advantages of Vertical Broaching Machine

Posted on by

Vertical broaching refers to the type of machine that is used to broach a piece part. Vertical broaching machine is typically used to cut external slots, shapes, and forms. Each application of vertical broaching usually consists of a custom made tooling package, and a fixture to hold and secure the piece part. An example of a vertical broaching application would be cutting a deep slot in a large industrial valve stem.

 

Vertical Broaching Advantages

 

  • Typically faster than traditional horizontal broaching methodology, without compromising length or size of cut
  • Machinery can be specifically matched to the part being cut, for a more efficient cutting operation
  • Well suited for cutting external shapes and forms quickly, while still holding close tolerances
  • Extremely economical cutting process, very often superior to milling
  • Tooling can be modular in design, allowing for variations of the same basic cutting pattern
  • Different cutting operations can be optimized on the same dual ram machine

 

Vertical broaching machines come in many varieties and adaptations, but in general any machine in which the ram is mounted vertically, instead of horizontally, is classified as a vertical broaching machine. In the case of surface broaching, the ram, which carries its broaching tools mounted in holders, typically moves past the piece part. The piece part is secured in a fixture using hydraulic or mechanical clamps. Some traditional vertical broaching machines are dual ram, meaning that there are actually two rams mounted on the same machine, and sharing the same hydraulic and mechanical systems. In many cases the part is secured in a shuttle table or swing table, so that the operator can load one piece to be machined, while the other ram is cutting another piece at the same time. Dual ram vertical broaching machines can also be used to cut two or more successive operations on the same part.

 

Vertical broaching machines can also be used to cut internal shapes and forms, and can perform very much like traditional horizontal machines. In each case either the piece part is secured while the broaching tool moves past it, or the broach itself is secured while the piece part travels on a table. The former type of machine can be either of the vertical pull-down or pull-up variety (referring to the motion of the broaching tool). The latter is typically referred to as a table-up vertical broaching machine.

How Do Industries Benefit From Using a Milling Chuck?

Posted on by

A milling chuck is a small piece of metal that connects the cutting tool to the machine. Many industries make use of clamps to hold onto interchangeable tools or drill bits. In the metalworking industry, though, special collars are needed to secure the heavy duty cutting edges used in metal machining. The most common clamp used in metalworking is the collet, or an unusually shaped collar that tapers into a cone at one end. Its unique design enables it to handle a large number of tool sizes and some models can accommodate square or irregularly shaped tools.

 

Compared to other processing machines, metalworking devices are designed a little differently. In most setups, like with a standard power drill, the clamp rotates with the cutting tool or bit while the device remains stationary. A milling chuck is designed to remain in place while the machine itself provides the rotation for the cutting tool. This requires a specially-designed clamp that can handle these unique working conditions. Metalworking, in most cases, must be much more precise than simple drilling, and collets provide this extra precision.

 

This is because the collet is built with a metalworking machine in mind. Metalworking devices are compatible with a number of clamps, but many of them may produce runoff or result in a sloppy cut. Collets are the ideal milling chucks, because they align the cutting edge with the machine better. The improved stability is produced through the collet’s design. Most clamps aren’t tapered on one end and use a series of gripping jaws to grab a tool. A collet, though, grabs the tools much more tightly. Before starting the machine, the cutting tool is placed inside the collet, which can be secured loosely. This grip is enough to hold the tool in place, but it will not provide a stable cut when the machine is in operation. However, once the collet is placed inside the metalworking device, the machine exerts additional force on the clamp, which creates a tighter grip on the tool. Inside the collet, the inner contact surface spins with the cutting tool, resulting in smooth mechanical energy transfer from the machine to the tool.

 

The tapered, conical edge compresses slightly when the milling chuck is tightened into place once inside the metalworking machine. This creates great static friction with the cutting tool, resulting in an extremely tight fit. A stable tool is the best tool when trying to make precision alterations to a piece of metal.

 

Collets and other clamps can be found in a huge number of sizes and designs. The most common designs are the R8, which are built for manual mills, and the 5C, which are designed for lathes. A milling chuck can be sized for tools less than an inch in diameter to pieces several inches wide. No matter the size, the clamping principle is the same. Collets that are made for irregularly shaped tools are known as emergency collets, or e-collets.

 

Precision and stability are the two most important things to keep in mind when working with metal. Without these, the machine will wear down faster, damage product, and cause a major safety hazard. For this reason, it’s smart to invest in clamps specifically made for metalworking machines.

What You Need To Know About Diamond Grinding Wheels

Posted on by

Do you know how diamond wheels are classified?

Diamond wheels are actually classified according to shape, concentration, bond, and grit size. These wheels are used in various grinding and abrasive machining operations. Consequently, diamond grinding wheels are used in grinding machines. In any machining or grinding process, it is always important to use the appropriate grinding wheel.

 

One of the most widely used grinding wheels today is the diamond and CBN wheels. These come in several types including resin, vitrified, metal, and electro-plated. The most common among these types is the resin wheels. These are used in most tool room and production applications. On the other hand, the vitrified and metal types are newer bond types and are used in specific applications. These are rare and are more expensive. Moreover, these are usually custom made order items. However, electro-plated wheels are typically found in cut-off wheels and low demanding abrasive grinding such as that for plastics.

 

It is very important to know the different types of diamond grinding wheels and their applications because each of these types is particularly used on specific applications only. Moreover, if you are not using the appropriate wheel type, grinding operations may not be done effectively. Thus, before embarking on any grinding operations, it is essential to determine the type of material to be worked on, and the type of grinding wheel as well.

 

Diamond and CBN grinding wheels are used in a variety of processes and materials. However, diamond wheels are used strictly on carbides while CBN is used on steels. In some cases though, there are some manufacturers that produce a special grit that can be used on both carbides and steels.

 

The three types of diamond grinding wheels that are available in the market are synthetic diamond, cubic boron nitride (CBN), and alumina-zirconia. Among these three types, the synthetic diamond is the hardest, while alumina-zirconia is the softest. In selecting the particular type of wheel, there are some important factors to consider.

 

First and foremost, it is essential to determine the hardness of the item you will be grinding. You should always remember that CBN is most advisable for iron or steel. If the metal is nonferrous though, and a large amount of metal must be removed, a synthetic diamond blade is the most appropriate wheel to use. For soft metals, alumina-zirconia should be used.

 

Second, look at the nomenclature plate on the grinding apparatus. The speed rating in meters per second is very important in ensuring that the bond of the diamond grit will not separate or disintegrate when used on the grinding apparatus.

 

Third, determine if the grinding will be done wet or dry. A wet diamond grinding wheel is used for precision cutting while a dry diamond grinding wheel is used for moderate grinding purposes.

 

Finally, select the coarseness of the wheel according to the amount of metal that will be removed. A coarse grit is most appropriate for fast cutting while a fine grit is used for a finish quality cut.

Basic Information of CNC Rotary Table

Posted on by

A CNC rotary table is a disc-shaped metalworking device used to obtain precise workpiece positioning. It enables a metalworker to cut or drill a workpiece at precise intervals around a vertically or horizontally fixed axis. A rotary table can be both manually or computer numerical controlled. Certain types of rotary tables are designed to be used with indexing plates or dividing plates for specialized operations. A rotary table used together with one of these positioning plates is generally referred to as a dividing or indexing head.

 

The CNC rotary table device typically has a solid base that can be attached to a separate fixture or table using clamps. This device is basically a rotating disc which holds the workpiece in place during cutting or drilling operations. The disc portion of a rotary table can be freely rotated for indexing procedures or turned by an attached control arm known as a worm wheel. Tables used in high precision operations are typically turned by a duplex-type worm wheel to compensate for backlash. Rotary tables used in automated metal working processes are turned by computer numerical controlled machinery.

 

CNC rotary tables are most often used in a flat position with the table’s axis having a vertical orientation. They are sometimes mounted with the axis oriented in a horizontal fashion so that a tailstock can be used to support the free end of the workpiece. When this device is attached to a secondary table, the workpiece can be centered on the rotary table’s axis which is then centered on the cutting tool’s axis. In this configuration, the axes of the rotary table, secondary table, and cutting tool are coaxial to facilitate concentric cutting operations. This configuration also permits the secondary table to be offset for drilling equidistant holes in a workpiece.

 

It is also a necessary component for many different types of machining and milling procedures. This versatile device can be utilized to perform specialized tasks such as machining spanner flats on bolts and drilling holes in flanges. In certain other configurations, a rotary table can also be used cut complex curves, arcs, and round pieces with protruding tangs. Rotary tables are sometimes used to produce a large-diameter hole in a workpiece by cutting in a tight circular path. This device can also use in place of a lathe when it is operated by a stepper motor combined with a computer numerical controlled milling machine and tailstock.

Information of Tailstocks and Bench Centers

Posted on by

Tailstocks are used on lathes and other machine tools to support one end of the workpiece through contact with a live center or dead center. Bench centers are table top mounted units used to support a workpiece between two tailstocks during inspection. A tail stock is a cast iron assembly that can slide along and be locked in place, and is used to hold long work in place or to mount a drill chuck for drilling into the end of the work. There are two types of tailstocks: manual and pneumatic. Manual tailstock requires workmen to apply pressure. Pneumatic tailstocks are driven by machines. If tail stocks are used, a dead center (which is non-rotating) may be used to support the workpiece, alternatively, a live center may also be used. Lathes with cylindrical tailstocks that can rotate around a vertical axis are turret lathes. All lathes have a bench centers, which is a horizontal beam.

 

All tailstocks are Morse Taper #3. Bench centers are precision ground tapered cylinders with a 60º pointed tip and a Morse Taper shaft. A tailstock handwheel is a wheel with a handle and is used to move the tail stock ram in and out of the tail stock casting. Tail stock ram is a piston-type shaft that can be moved in and out of the tail stock by turning the tail stock handwheel. It has a tapered internal bore to accept a #2 Morse Taper shank. A lathe may or may not have a stand (or legs), which sits on the floor and elevates the bench center to a working height. Some lathes are small and sit directly on a workbench or table, and do not have a stand. A bench center is an important lathe component and is available in various sizes according to the work piece requirements. An inspection accessory is necessary for various machine-works to check the efficiency of the work piece. Aligning tailstock includes mounting a small center drill in the tail stock, turning the bar between centers and measuring the diameter of bar, and putting a straight bar between centers. Bench centers are generally used for long work pieces. Tailstocks must be aligned with the spindle within .0005 before beginning drilling operations.

Applications

 

Tailstocks and bench centers are used in many applications in lathes. Drilling, reaming, center drilling and countersinking are performed on the lathe using tailstocks and bench centers. Tailstocks and bench centers should adhere to various standards specified by International Standards Organization (ISO).

Some Knowledge about Lathe Chuck Jaws

Posted on by

A lathe chuck is a special kind of clamp used on a lathe. These chucks hold objects that are cylindrical, radial, or irregularly shaped, gripped by what are called lathe chuck jaws. Used on wood lathes for woodworking or on machinists’ lathes for machining, chuck jaws hold steady the objects to be worked on. On some lathes, it is the chuck that does the rotating while a power tool is steadily applied to the object in its grip. The lathe chuck jaws are usually tightened into place on the object using a chuck key, a t-shaped wrench.

 

One type of lathe chuck is called a centering cylindrical stock chuck, having circles on its faceplate that can be used to center an object being machined. The lathe chuck jaws open wide to accept the object and center it, then the individual jaws are tightened snugly, yet carefully, so that there won’t be any movement whatsoever of the object once rotation begins. A dial indicator mounted on the lathe centers the object and measures to be certain that each of the individual jaws is bearing an equal grip on the object. Relatively large movements of the object eventually become only slight movements, as it is perfectly aligned and centered.

 

Another type of lathe chucks are specialty chucks. These lathe chucks come in two-jaws, six-jaws and eight-jaws configurations. The right choice of lathe chuck jaws for these depends on the type and heaviness of the objects to be handled, and on how important perfect centering and tightness of grip will be. For example, six-jaw self-centering lathe chuck jaws are used for thin-walled work pieces or for gripping finished edges of work pieces, and the large number of jaws enables less pressure per grip in order to protect a finish. Two-jaw chucks are available in a soft jaw aluminum configuration to work more like a stop to hold custom fixtures for tooling. Most chucks have one resident jaw as a master jaw, but the other lathe chuck jaws can be purchased or replaced separately at any time.

 

Three-jaw chucks have both inside and outside lathe chuck jaws with concave surfaces and are used for handling large diameter objects of circular or hexagonal shape. One type of three-jaw chuck is called a drill chuck, and it is for specialty self-centering to hold drill bits and other similar rotary tools. Another three-jaw chuck is the one colloquially called Super Chuck, which uses ball thrust bearings, has high torque and is used in high precision work. Three-jaws chucks can’t hold irregularly shaped pieces or any square shapes, yet the variety of types of three-jaw chucks for different purposes keeps them in high use.

 

Another high precision lathe chuck jaws configuration are the four-jaws chucks. These have time-consuming individually setting jaws, yet can turn in offset position as when turning cams. Four-jaw chucks can hold square, rectangular and nearly any irregularly shaped object for high-precision work. They also have more grips for handling round shapes or thin walled work pieces that need more numerous, gentler grips to spread the tension against the surface.

Advantage of Adding A 4th Axis Rotary Table to Milling Machine

Posted on by

To add a 4th axis rotary table to a milling machine in any sort of work setting provides several advantages to machine work. Having another axis to work with gives milling machine users more precision and accuracy without having to change positions of the part being machined.

 

Also, an additional axis would prove to make any milling machine more diverse in the work it is capable of doing; lathe machines introduce the aspect of a rotating part, so a rotary table would add the same benefits provided. A 4th axis rotary table, in general, can provide more precision and ease to a complex design, reducing time and costs for the production of a certain piece.

 

How It Works

 

To clarify, a 4th axis rotary table serves to add a rotating aspect to the desired piece being shaped. Similar to a lathe’s rotating head-stock, the rotary table serves to hold the piece and move at exact intervals of revolutions. Because it can move in precise degrees of motion, users can easily calculate correct positions, just like it can be done with the other three axes of motion on the machine. Once all four axes are used, making grooves or holes in the piece is much easier than without the rotary table, saving time by discarding the task of removing and resetting the piece in another position. Having the ability to move the piece in determined intervals and precision with diverse planes of motion is important for more complex machine work.

 

The Importance of a 4th Axis Rotary Table

 

Just like with the other three axes of motion, the 4th axis rotary tables can be adjusted for specific amounts of distances to accurately tell what position you are at in relation to the dimensions of the piece. Furthermore, the scales used to measure its motion can save time and resources by reducing the amount of mistakes that could result in major delays, such as re-working the piece from the beginning. Since users will easily be able to calculate and set the positions needed for the work done, machining multiple pieces is simpler to accomplish.

 

Examples of Diversity

 

As stated before, the rotary table adds more diversity to the work the milling machine is capable of doing; some work required with a lathe can be done with the additional axis of motion. Machining the part with holes, for example, may require the user to work with a circular pattern with equal distances, which is certainly possible with 360 degree movements. Along with cutting circular patterns easily, arc cuts, grooves, and other complex curves are included with the benefits of a rotary table; cutting out the teeth of gear parts is another way of work possible.

 

The capability of a 4th axis rotary table is only limited by the skill of the user. It is able to provide the extended degree of motion necessary for complex work needed by any skilled machinist. With quality parts, a machinist is capable of intricate pieces of work, and it would be limiting to not have another axis of motion available. It is important to consider the expansion of work choices for machine work, and this addition is a good starting point for such consideration.

A Brief and Fast Introduction about CNC Milling Machines for Newbies

Posted on by

When it comes to fabricating components, Computer Numerical Control (CNC) milling machine is one of the most important CNC machine tools which are widely used in many industrial businesses. It has been effectively used to increase one’s profitability as well as productivity in performing repetitive high precision and difficulty milling operations including drilling, slot and keyway cutting and many more, which these tasks could not be possibly done manually over a long period of time. Therefore, these CNC milling machines are a compulsory tool in most industrial businesses which has succeeded the traditional milling methods.

 

If you are a newbie and you would like to know what this particular milling machine capable of – here are some things that you should know:

 

  1. There are existed as two distinctive types of milling machines – These machining centers are differentiated based on the positioning of the spindle motor (or orientation of the cutting tool). These machines are called horizontal milling machines because of the cutting tool is positioned and operating horizontally and vertical ones vice versa. Hence, it is common to see two types of these machining centers in most manufacturers – either in large or small manufacturers, as these machine tools are capable to perform milling operations in different directions.

 

  1. Most of these CNC milling machines can perform versatile cutting and drilling operations – There are several types of these CNC machining centers that are well-known as multiaxis machining centers including 3-, 4- and 5-axis machines. Certainly, those machines which have the higher number of axes are cost higher than lower numbered axes because these machines are able perform intricate parts production. Thus, normally large scale manufacturers own 4-and 5-axis machines as both machine types are able to boost their productivity and profitability over a certain period of time.

 

  1. These machines have integrated control software – Basically, CNC milling machine operations are controlled by its own distinctive control software. Operators need to be proficiency in CAD and CAM programming skills in order to control the computerized machining centers when performing high precision milling operations. As compared with traditional milling machines (or manual machines), most CNC machining centers are able to perform high precision milling operations and to reduce unnecessary wastage.

 

  1. Most of these machining centers are ergonomically designed – Based on its ergonomic features, operators will not be forced to bend, crouch and contort your body during setup. Furthermore, the cutting tool is operating within an enclosed area is an effective preventative measure of avoiding unwanted accidents resulted from direct exposure of milling operations.

 

  1. Wastage is not a big issue for CNC milling machines – As mentioned earlier, most CNC machines are capable of fabricating components without sacrificing precision and quality. Thus, using such CNC machines can effectively reduce one’s overhead costs.

 

  1. CNC machining centers are also available in job shops – It is not necessary that a manufacturer has to machine components on their own. In most cases, they would outsource specific tasks – i.e. tasks which involved CNC milling process, to CNC service providers.

 

Be sure that you understand the benefits of having CNC milling machines before you start purchasing them.
