Work Holding Devices Used on Milling Machine

The plain vice is directly bolted on the milling machine table is the most common type of vice used on plain milling operations, which involves heavy cuts, such as in slab milling. Its especially low construction enables the work to remain quite close to the table. This reduces the chance of vibration to a minimum. The base carries slots to accommodate ‘T’ bolts to fix the vice on the table. Work is clamped between the fixed and movable jaw and for holding workpieces

dividing head – holding the workpiece john f's workshop

The mandrel should be pressed in as hard as possible without using any extra aids. If the workpiece slips on the mandrel at all during machining usually the whole job will be ruined. Since there is only one place on the mandrel, which tightly fits the workpiece, it is only possible to hold one workpiece at a time on this sort of mandrel. It also follows that a tapered mandrel should not be used for very long workpieces

Similar to parallels in their possible uses are blocks. One common sort of block is the 1-2-3 block. These are so called because a common size for them is 1in x 2in x 3in. Blocks can be used to hold a workpiece rigidly when the workpiece would otherwise be too high to hold safely in the vice. Blocks are also useful to hold very long workpieces. It is often difficult to ensure they are parallel to the milling

Milling machines exist in two basic forms: horizontal milling machines and vertical milling machines, which refer to the orientation of the cutting tool spindle. Unlike a drill press, in which the workpiece is held stationary and the drill is moved vertically to penetrate the material, milling also involves movement of the workpiece against the rotating cutter, the latter of which is able to cut on its flanks as well as its tip.
