At present, most manufacturing enterprises do not have five-axis machining equipment, because the cost of buying a five-axis machining center is more than 2 million yuan, which is impossible for enterprises to pay. And the penetration rate of three axis CNC milling machine is very high, inexpensive, considerable earnings, can bring stable earnings for enterprises. When the three-axis CNC milling machine cannot be combined with the general fixture for parts processing, it is necessary to design and manufacture special fixture for milling machine. Special fixture can obtain higher generation efficiency and processing accuracy, but the design and manufacturing cycle is long, there is no universality, and there is no advantage in small batch parts processing.
