ZK21 Series CNC Gun Drills Machine

Short Description:

This machine is a deep hole processing equipment for drilling cylindrical bar materials. It is a high-efficiency, high-precision and high-automatic machine tool for drilling small holes with external chip removal method (gun drilling method). Through one continuous drilling, the processing quality that can be guaranteed by the general drilling, expanding and reaming procedures can be achieved. The hole diameter accuracy is IT7-IT10, the surface roughness is Ra3.2-0.04μm, and the straightness of the hole center line is ≤0.05mm/100mm.
