At present, the spindle speed of the ordinary gantry CNC milling and boring machine made in China is generally 0~3200r/min, which can realize the three-axis linkage.
Each shaft adopts the ball screw transmission structure, and both are closed-loop structures, and the grating is used for tracking and detection. And adjustment, the transmission accuracy can reach 0.001mm. The tools commonly used at this stage are hard alloy materials, which have good processing properties due to their high heat resistance and wear resistance. 
The use of cemented carbide tools, according to the performance of the processing materials, the selection of reasonable processing parameters, to improve the processing efficiency, and effectively reduce tool consumption has a very important role.
