Description
CNC turret lathe CK61125 The bed is adopted high strength cast iron, after 3-time tempering so that it has high rigidity and vibration resistance. Big spindle bore lathe is mainly a special machine tool for pipe thread turning processing, and it can also be used for turning outer circle, boring and flat surface of common lathe. It is applied to processing and repairing drill pipe, drill collar, square drill pipe and casing in petroleum, metallurgy, chemical industry, hydropower and geological departments.

Features
-
With feeding motor and leadscrew for type of direct connection, it can assure the machining precision and positioning accuracy.
-
Headstock takes symmetrical structure to make thermal deformation be even, avoiding the spindle center generates offsets.
-
Headstock adopts oil bath circulating lubrication to reduce thermal deformation;
-
Frond end of the spindle adopts three-supporting structure of two-way angular in touch with the ball bearing to improve its accuracy and enhance its rigidity;
-
Gears in headstock and guide way are processed by quenching to ensure accurate transmission and high rigidity.
