Work Holding Devices In Milling Machine Pdf Download


Work Holding Devices In Milling Machine Pdf Download




Milling is a machining process that involves the use of a rotating cutting tool to remove material from a workpiece. The workpiece is typically held in a vise or clamped directly to the table of the milling machine. However, there are many other types of work holding devices that can be used for different purposes and applications. In this article, we will introduce some of the most common work holding devices used on milling machines and provide links to download their pdf files.

T-bolts and clamps




T-bolts and clamps are the simplest tools available to secure anything to the T-slot table of the milling machine. They consist of a T-shaped bolt that fits into the slot and a clamp that holds the workpiece or workholding tool in place. T-bolts and clamps can accommodate various sizes and shapes of workpieces, but they have some disadvantages, such as difficulty in positioning and aligning the workpiece, low clamping force, and interference with the cutting tool.

Angle plates




Angle plates are used to support and hold workpieces that need to be milled at right angles to another face. They are made of high-quality material, such as cast iron or steel, and have slotted holes or T-slot slots for attaching or clamping the workpiece or other workholding tools. Angle plates can also be used to hold the workpiece square to the table during marking-out operations. Adjustable angle plates are available for workpieces that need to be inclined towards the milling cutter. You can download a pdf file about angle plates [here].


V-blocks




V-blocks are used to hold cylindrical or round workpieces on the milling machine table. They have a V-shaped groove that matches the diameter of the workpiece and provides a stable and accurate support. V-blocks can be clamped to the table or attached to other workholding devices, such as angle plates or indexers. V-blocks can also be used for measuring and inspecting cylindrical parts. You can download a pdf file about V-blocks [here].


Machine vices




Machine vices are one of the most basic and versatile types of workholding devices used on milling machines. They have two jaws that grip the workpiece firmly and accurately, and a screw mechanism that allows for easy adjustment and clamping. Machine vices can be mounted on the table or on other workholding tools, such as fixture plates or rotary tables. Machine vices can hold various shapes and sizes of workpieces, but they may limit the access to some features of the part. You can download a pdf file about machine vices [here].


Dividing head




A dividing head is a special workholding device that allows for dividing the workpiece into equal parts or angles. It consists of a spindle that holds the workpiece, a worm gear that rotates the spindle, and an index plate that controls the amount of rotation. A dividing head can be used for milling gears, splines, flutes, slots, and other features that require precise angular positioning. A dividing head can also be used for drilling, boring, reaming, and tapping operations. You can download a pdf file about dividing head [here].


Special fixtures




Special fixtures are custom-made workholding devices that are designed for specific parts or operations. They provide a high degree of accuracy, rigidity, repeatability, and productivity. Special fixtures can incorporate various elements, such as clamps, pins, bushings, locators, supports, guides, etc., to hold and position the workpiece securely and precisely. Special fixtures can also include hydraulic or pneumatic systems for automatic clamping and unclamping. You can download a pdf file about special fixtures [here].


Circular table or indexing table




A circular table or indexing table is a workholding device that allows for rotating the workpiece around a vertical or horizontal axis. It consists of a circular plate that holds the workpiece or other workholding tools, such as vices or chucks, and a mechanism that controls the rotation angle. A circular table or indexing table can be used for milling circular or curved features, such as arcs, circles, slots, etc., as well as for drilling or tapping operations. You can download a pdf file about circular table or indexing table [here].


Parallels




Parallels are used to raise the workpiece or workholding tool above the table surface. They are rectangular blocks of metal that have precise parallel faces and dimensions. Parallels can be used to adjust the height of the workpiece or workholding tool, to provide clearance for the cutting tool, or to align the workpiece or workholding tool with the table or other reference surfaces. Parallels can also be used as spacers or supports for clamping or holding the workpiece or workholding tool. You can download a pdf file about parallels [here].

Fixture plates




Fixture plates are flat plates that have a pattern of holes or slots for attaching or clamping workpieces or workholding tools. They are used to provide a rigid and stable base for milling operations. Fixture plates can be customized to fit specific parts or applications, or they can be standardized to fit common workholding tools, such as vices, chucks, or clamps. Fixture plates can also be used to mount multiple workpieces or workholding tools on the same table, increasing the efficiency and productivity of the milling process. You can download a pdf file about fixture plates [here].


Rotary table




A rotary table is a workholding device that allows for rotating the workpiece around a horizontal axis. It consists of a circular plate that holds the workpiece or other workholding tools, such as vices or chucks, and a worm gear that rotates the plate. A rotary table can be used for milling spiral or helical features, such as gears, worms, cams, etc., as well as for drilling or tapping operations at any angle. A rotary table can also be tilted to mill at an inclined angle. You can download a pdf file about rotary table [here].

Arbor and collet




An arbor and a collet are workholding devices that are used to hold and drive the cutting tool on the milling machine. An arbor is a shaft that has a taper at one end and a threaded hole at the other end. A collet is a sleeve that has a tapered bore and a slit that allows it to contract and grip the shank of the cutting tool. An arbor and a collet can be used to mount various types of cutting tools, such as end mills, face mills, slitting saws, etc., on the spindle of the milling machine. You can download a pdf file about arbor and collet [here].


Chuck




A chuck is a workholding device that is used to hold and rotate the workpiece or the cutting tool on the milling machine. A chuck has three or four jaws that can be moved in or out by a key or a lever to clamp the workpiece or the cutting tool. A chuck can be mounted on the spindle or the tailstock of the milling machine, depending on the type of operation. A chuck can hold various shapes and sizes of workpieces or cutting tools, but it may reduce the accuracy and rigidity of the setup. You can download a pdf file about chuck [here].
