Abstract
A protective enclosure for a machine tool is constructed so as to be a free standing assembly completely independent from the machine tool. The protective enclosure is provided on rollers so that unimpeded access may be had to the machine tool by rolling away the protective enclosure. The protective enclosure is further provided with a safety locking system for interrupting operation of the machine tool if the protective cover is removed during operation or preventing starting of the machine tool if the protective cover is not fully in place.
