ZK2302/ZK2303 Series 3D CNC Deep Hole Drilling Machine

This machine is a deep hole processing equipment for drilling holes with 3D workpiece. 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 can reach IT7-IT10, the surface roughness can reach Ra3.2-0.04μm, and the straightness of the hole center line is ≤0.05mm/100mm.

All our products have to go through three separate checks throughout the whole manufacturing process: materal, every part for assembly and accuracy inspection or finished products, We control quality from raw materials, we always select the best quality raw materials, and we have an quality inspector for each process, quality is always our top concerned.
