CNC lathe consists of CNC device, bed body, spindle box, knife frame feed system, tail seat, hydraulic system, cooling system, lubrication system, debris cleaner and other parts. CNC lathe can be divided into vertical CNC lathe and horizontal CNC lathe. Vertical CNC lathe is used for turning machining of disc parts with large rotary diameter. Horizontal CNC lathe is used for machining of long axial size or small disc parts.

CNC lathe is mainly used for the cylindrical and inner cylinders of shaft parts or disc parts, any cone angle, complex rotary inner and outer surfaces and columns, conical thread, and can be cut, drilling, expansion, hinge and boring. CNC lathe has the characteristics of high machining precision, straight line and arc insertion and automatic speed change in the hardware processing process.
