Spindle:100 mm in diameter, mounted with NN type double row roller bearing, especially good for heavy duty cutting. Direct gear drive is employed for spindle with auto gear change. Full power output can be obtained from merely 196 rpm. Spindle and transmission gears are equipped with a forced cooling system to reduce heat and ensure accuracy. The headstock is mounted on the siding surface of the column with 8-faces wraparound enhancing rigidity and allowing heavy duty cutting.
Headstock and column are symmetric construction designed, which can minimize the thermal deformation .
