Adopt SIEMENS 828D numerical control system to realize five-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
W-axis: dresser carriage horizontal motion
Among them, C and Z axes are linked to realize thread movement; W and V axes are linked to dress the grinding wheel through diamond rollers; two electronic handwheels are configured to manually control the movement of each numerical control axis of the machine tool.

• Rear-mounted hydrostatic bearing grinding wheel spindle greatly improves the surface quality of the workpiece after grinding.
• The optimized head frame doubles the speed of the workpiece during grinding, greatly improving the processing efficiency of the machine tool.
• The multi-time optimized CNC grinding wheel dresser makes the dressing accuracy of various shapes of grinding wheels higher and the dressing flexibility better.
• Constant temperature, large flow, dual filter cooling system upgrades and multi-point workpiece shower cooling device development, so that the ball screw machining accuracy is greatly reduced by the degree of temperature.
• Intelligent grinding software, through the man-machine hand-over flexible and convenient way to achieve a variety of grinding wheel shape dressing and different workpiece grinding.
