3 axis cnc mill v1165 fault repair for unsatisfactory surface roughness
1. Trouble phenomenon: When a CNC gantry milling machine uses the right vertical tool post to mill the product frame plane, it is found that the surface roughness of the workpiece does not meet the predetermined accuracy requirements.
Analysis and processing process: After the occurrence of this fault, focus on finding the fault on the accuracy of each rolling bearing (especially the front and rear bearings of the spindle) in the right vertical tool post headstock, but the unexpected is the rolling bearing All were normal; afterwards, after research, analysis and careful inspection, it was found that the four pipes that provided lubricating oil for the transmission pair of the workbench worm and the nut bar fixed at the lower part of the workbench basically did not supply oil. After adjusting the four needle-shaped roller valves arranged on the CNC machine bed to control the oil output of the four oil pipes, the fault disappears after the flow of the lubricating oil pipe is normal.
