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.

The grinding ball screw of the machine tool can reach P2 grade, and the accuracy conforms to GB/T17587.3-1998(ISO3408-3:2006); The inspection tool is the screw dynamic measuring instrument.
• Grinding trapezoidal lead screws up to level 6 (meets JB2886-1992).
-
• The rear-mounted motor 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.
