In the field of machining, CNC machining belongs to precision machining equipment. CNC machining center can complete a variety of processes of automatic state of CNC equipment, mainly for some mechanical equipment, mobile phone communication industry, small batch, large batch parts production and processing operations. But for the mold industry, small batch production and processing has no obvious advantage, many mechanical processing factory home CNC machining center when CNC milling machine to use.
CNC machining center has its own tool magazine. It is very simple to use the tool magazine for the cost of CNC system, but the cost of machine spindle and tool magazine, auxiliary air compressor and various tool handles will increase, and it will take time to program and adjust the tool magazine with computer. Therefore, for the production and processing of a small number of workpieces of the same variety, the machining center should not be used as far as possible, because the cost will be high and the efficiency will be low.
Precision CNC machining center is an automatic numerical control equipment, which can use the full-automatic tool setting system. The tool is installed upward, the operation button, the machine tool automatic tool setting, and direct processing. The error is within 0.003 ~ 0.005mm, which is not much slower than the automatic tool changing time. If it is a general machining center, but there is no automatic tool setting device, compared with the machine without tool magazine, but there is automatic tool setting device, the efficiency of the latter is much higher than the former in practice. Improve the efficiency of production and processing!
Nowadays, the domestic machinery manufacturing industry, especially the mold manufacturers, is generally single piece production and processing, and labor resources are sufficient, CNC machining center has no obvious advantage. Only in the mechanical parts processing industry, to a certain small batch processing, precision CNC processing will have obvious advantages. The tool magazine on the machine tool plays an important role!
