CNC Deep Hole Machining Center

1.This machine tool is a specialized equipment for machining cylindrical deep-hole components, applicable to the processing of various hydraulic cylinders, spindle bores, cylinder holes, cooling holes and other similar workpieces. The dimensional accuracy of the workpiece bore diameter can reach IT7 ~ IT10, and the inner hole surface roughness can achieve Ra3.2 ~ 12.5μm.

All castings of this machine tool adopt the design concept of box-type structure and are optimized through finite element analysis (FEA), which endows the machine with reasonable weight distribution, high rigidity and high precision.

All castings are manufactured with high-strength cast iron by resin sand molding. After casting, all castings are subjected to normalizing treatment, and another normalizing process is conducted after rough machining. This eliminates the internal stress generated in the casting process and the machining stress produced during rough machining, ensuring excellent precision stability of the machine tool.
