Engraving and milling machine and CNC milling machine, spark machine processing area

Engraving and milling machine set the CNC milling machine and spark machine respective function, make up for the inadequacy of their processing capacity. These three models in the processing area has the following characteristics: 1, a large quantity of CNC milling machine for processing chip to artifacts, spindle power is relatively strong. 2, spark machining in milling machine can't complete parts: multi-cavity, precision, small and not easy to cutting material. 3, engraving and milling machine can be in the high speed machining, small to the amount of scrap steel, and used for high speed cutting of non-ferrous metal electrodes etc.
