Vises and their Use
Points : Vises and their Use, Definition Definition To make the various setups for performing milling machine operations, numerous work-holding devices are used. Their use greatly extends the range of work that can be efficiently done on milling machines. The work must be securely fastened milling operations.


The most commonly used method of holding work on the milling machine is with the vise. Vises are simple to operate and can be quickly adjusted to the size of the work piece. The operation of clamping work in a vise is one that is fundamental for machine shop workers. Work can be secured quickly and accurately in a vise and, besides, can be released with a minimum of effort and with maximum pee Vises used in milling work are designed to hold the work securely and to give rigid support against the pressure of the cutter. The milling machine vise is designed so that the jaws are kept as near the face of the table as possible, so that the cutting stresses can be withstand more readily. Vises are accurately made. The jaws are hardened to resist Wear and ground for accuracy, and may have replaceable. The bases of most vises are fitted with Keys, or Lugs, which are small blocks of steel that fit into the milling table T-slot to provide quick alignment of the vise. Vise sizes are designated by the width of the jaw in millimeters or inches.
