Product description
Machine tool uses and features
CGK-83 CNC screw grinding machine is mainly used for grinding machine of batch grinding high precision screw machining, wide range, high rigidity, high working precision and has good man-machine interface, stable performance and high production efficiency.
Structure description of main parts of machine tool
1, bed
My bed into a bed, after using V- flat rolling guide, before bed using V- flat plastic guides, with protection device for folding rail bed material for high strength cast iron, after two times of aging treatment, in order to improve the accuracy of stability of the machine.
2, grinding wheel spindle
The main shaft of the grinding wheel is made of 2 pre load high precision contact rolling bearing with the electric spindle, the spindle bearing is lubricated by grease, the grinding wheel spindle motor can be AC variable frequency speed regulation.
3, working table (Z axis)
Working table by AC servo motor direct drive reducer by elastic coupling drives the ball screw directly drives the worktable produce longitudinal motion, and the formation of spiral movement and spindle rotation, the long trip by good protection for reference encoder.
4, tail frame
The tail frame adopts a double layer structure with adjustable taper, and an indicating device for the heat elongation of the workpiece can be displayed and indicated.
5, head (C axis)
The headstock adopts high precision rotary spindle, by AC servo electrode through the worm gear drive, speed can be set as required, by good protection as the rotary encoder and the reference motion separately.
