• CNC system adopts SIEMENS 828D high-grade CNC system to achieve five-axis three linkage.
• Number of control axes
C- axis: full closed-loop control of the rotary motion of the headstock spindle
Z axis: full closed-loop control of the longitudinal motion of the worktable
X-axis: full closed-loop control of grinding wheel frame transverse feed motion
W axis: full closed-loop control of grinding wheel movement
Axis A: lead angle adjustment movement of grinding wheel shaft
Among them, C and Z are linked to realize thread movement; electronic handwheel is configured to manually control the movement of each CNC axis of the machine tool.

• Methods of measurement
The lead accuracy of the screw is accepted according to the thread detection method, the profile accuracy of the screw is detected according to the shape of the screw end face or the coordinates of the screw surface, and the error value of the screw space surface coordinates and the theoretical coordinates in the normal direction of the surface is compared.
• Accuracy
Screw lead accuracy: 0.009mm on 300mm
Screw profile accuracy: 0.02mm
-
• Fully digital automatic control
It has intelligent functions such as intelligent optimization of process parameters, self-tuning of machine tool parameters, automatic avoidance of spindle vibration, fault maintenance based on two-dimensional code, synchronous dynamic error compensation of Z and C axes, machine tool load diagram in the whole life cycle of feed axis, machine tool assembly quality and consistency detection and analysis, etc.
