This product is a kind of lathe which the X and Z axis control the half close loop CNC lathe by direct-connected servo. All the two axis are the sliding (hard) rail. The structure and dimension of axis are compact and reasonable. Spindle is gear transmission and fvariable- frequency variable-speed drived by variable frequency motor through belt which can clamping various plate, shaft, and component all at once. It can complete the processing of vehicles, groove, inner (outer) hole, spherical, R cone angle, curved shape, cone shape, face shape, male thread single head, thread single head and multiple thread processing. It is applicable for multi and mass production, and can meet the processing demands for complex and high precision parts.
