• Adopt SIEMENS 828D numerical control system to realize four-axis three-linkage control.
• Number of control axes
Z axis: the longitudinal movement of the working table configuration grating ruler full closed-loop control
X-axis: cross feed movement of grinding wheel carriage
C axis: headstock spindle rotary motion configuration angle encoder full closed loop control
V-axis: Dresser Slide Vertical Motion
Among them, C and Z axes are linked to realize thread movement. Two electronic handwheels are configured to control the movement of each numerical control axis of the machine tool.
