Text 14 parts of machine tools
A
ll
machine tools
that use metal
to shape metal or other
materials have
similar parts to carry out the shaping process: a tool holder, to
keep the shaping tool in place; and a work holder, called a table
(or slide) to hold the part that is to be shaped and to move or feed
it at a fixed speed against the tool. In some machines the table is
stationary, and the tool moves. In addition, a means of controlling
the depth and angle at which the tool cuts the work-piece must be
provided. Both the rate of feed and the position of the
work-piece and the tool in relation to each other can be varied.
Cutting tools must be made of materials that are harder than the
metals and are capable of maintaining their cutting edge at
friction temperatures that result from the cutting operation. The
most common materials used are high-speed steel; non-ferrous alloys
containing tungsten, chromium, and cobalt; ceramicized aluminum
oxide; and diamonds. Water and various types of oil are used to
reduce friction temperatures and to lubricate the cutting area.
