Special requirements are imposed on this equipment at metal-working productions. This refers to a high level of accuracy in the manufacture of products compared to conventional machines. On CNC machines, programming of all movements is specified clearly in the coordinates of the equipment itself. As a result, it becomes necessary to accurately install the tool and the work piece in the fixture. In the machining cycle itself, quite a lot of time is spent re-installing the part. That is why you need to use a special quick-tightening tooling, which is equipped with a pneumatic and hydraulic drive. Also, in order to minimize the time of technological preparation, it is necessary to use unified devices or their layout
