• Adopt SIEMENS 828D numerical control system to realize six-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
Axis A: grinding wheel frame rotating cylinder horizontal rotary motion
V-axis: Dresser Slide Vertical Motion
W-axis: dresser carriage horizontal motion
Among them, the C and Z axes are linked to realize thread movement: the W and V axes are linked to dress the grinding wheel through the diamond disc wheel; The A- axis rotary motion realizes the automatic adjustment of the spiral angle. Two electronic handwheels are configured to manually control the movement of each CNC axis of the machine tool.

The grinding ball screw of the machine tool reaches P1 level, and the accuracy conforms to GB/T17587.3-1998(ISO3408 3:2006); The inspection tool is the dynamic measuring instrument of the screw.
• Grinding trapezoidal lead screws up to level 5 (in compliance with JB2886-1992).
-
• Rear-mounted motor and hydrostatic bearing combination of the grinding wheel spindle, so that the surface quality of the workpiece after grinding greatly improved.
• 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.
• Green manufacturing technology to enhance the overall machine safety and environmental protection, overall enhance the machine hydraulic, lubrication system leak-proof, anti-seepage technology and guide rail, motor, grating protection system.
