CNC lathes teach you how to troubleshoot CNC lathes
In the machinery industry, lathes are used a lot, and they generally handle large objects, so we also know that various problems may occur, so we need to investigate and then solve the corresponding faults, so as to meet the actual production Demand, improve work efficiency.
- 1. The CNC lathe manufacturer introduced that the workpiece size is accurate and the surface finish is poor. Troubleshoot the causes of the CNC lathe: the tool tip is damaged, not sharp, the machine tool resonates, the placement is not stable, the machine tool has crawling phenomena, and the processing technology is not good. Solution: The tool is not sharp after being worn or damaged, then re-sharpening the knife or choosing a better tool and re-setting the tool, the machine tool resonates or the placement is unstable, adjust the level, lay the foundation, fixed and stable, the cause of the machine crawling is dragging The guide rail of the board is badly worn, and the screw balls are worn or loose. The machine tool should be maintained.
- 2. The taper size phenomenon occurs in the workpiece. CNC lathe manufacturer introduced the reason for the failure: the level of the machine tool is not adjusted well, one high and one low, resulting in unstable placement, when turning the long axis, the contribution material is harder, the tool eats the knife deeper, resulting in the phenomenon of yielding, the tailstock thimble The spindle is not concentric.
Solution: Use a spirit level to adjust the level of the machine tool, lay a solid foundation, fix the machine tool to improve its toughness, choose a reasonable process and appropriate cutting feed to avoid the force of the tool, and adjust the tailstock. - 3. The CNC lathe manufacturer introduced that the driver phase lamp is normal, and the size of the processed workpiece is large and small. Troubleshoot the causes of CNC lathes: the machine tool pallet runs at a high speed for a long time, resulting in wear of the screw and bearing. The repeated positioning accuracy of the tool holder has a deviation during long-term use. The pallet can accurately return to the starting point of processing every time, but the size of the processed workpiece is still Variety. Solution: Use a dial indicator to lean against the bottom of the tool holder, and edit a fixed cycle program through the system at the same time, check the repeating positioning accuracy of the carriage, and adjust the screw clearance.
