main reason
Spindle encoder sent back to the machine tool system data inaccurate; X axis or Y axis screw and spindle movement is too large; preparation and input of the program is not correct.
Solution
Spindle encoder transmission of data is not accurate: maintenance of machine tools, replacement of spindle encoder or synchronous conveyor belt;
X-axis or Y-axis screw and spindle move too large: adjust the axial axial movement, X-axis or Y-axis gap clearance can be compensated with automatic compensation system gap;
Check the program so that the instruction lead in the program is consistent with the drawing requirements.
