(Gear, spline shaft, helical surface) and various surfaces can be machined (flat, vertical), grooves (keyway, T-groove, dovetail groove, etc.). CNC milling machine can also manufacture rotary body, the hole of the processing, and can be cut off processing. CNC milling machine work, the workpiece mounted on the table or sub-head and other accessories, the cutter rotation of the main movement, supplemented by the table or milling head feed movement, so that the workpiece to obtain the required processing surface. As a result of the multi-knife intermittent cutting, the milling machine has a higher productivity.
