Maintenance skills of spindle drive system of precision punch

    1. The precision punch manufacturer is familiar with the structure, performance and main parameters of the main drive system of the CNC machine tool to prevent the application of super performance.

    2. After the NC blade clamping device is applied for a long time, the gap between the hydraulic cylinder and the support rod will increase, resulting in less offset of the support rod, insufficient tension and expansion of the butterfly spring, which directly affects the clamping of the NC blade. Therefore, the offset of the piston rod of the hydraulic cylinder must be adjusted quickly.

    3. When the main drive system cannot work normally, it shall be shut down quickly to deal with common faults.

    4. Check the lubricating temperature control oil tank of the main shaft every day to ensure that the remaining oil is sufficient and normal in operation. Prevent all kinds of residues from entering the grease tank and ensure that the hydraulic oil is clean.

    5. For the balancing system that balances the net weight of the headstock by the hydraulic drive system, it is necessary to regularly query the vacuum pressure gauge of the hydraulic drive system of the high-precision high-speed punch. When the oil pressure is lower than the index value, it is necessary to quickly carry out oil replenishment.

    6. The operator shall carefully check the ambient temperature of the spindle box, check the oil tank of the spindle lubrication temperature control machine, adjust the temperature range, and make the remaining oil abundant.

    7. For the main transmission system with gear type electromagnetic brake, the clutch must be changed at a speed ratio of less than 1-2r / min.

    8. Pay attention to ensure that the taper hole of the spindle and the cutter bar are clean to prevent the impact on the mechanical equipment of the spindle.

    9. Clean the grease pool once a quarter, and remove and replace the oil filter of the hydraulic oil pump.

    10. Often check the working pressure of air compression and adjust it to the standard value. Sufficient pressure can completely remove the cutting and dust in the spindle taper hole.

    11. The main drive system of hydraulic press fork shifting shall be used to change speed after the main shaft of precision high-speed punch machine stops.

    12. The lubricating grease in the oil tank of the main shaft lubricating and temperature control machine shall be removed and replaced once a quarter, and the filter shall be cleaned.

    13. Using the spindle system software of the pulley, it is necessary to regularly query and adjust the tightening and loosening level of the spindle drive belt to prevent the loss of rotation caused by belt slip.

    14. Frequently check the tightness of the shaft end and various places of the main shaft to prevent leakage of lubricating grease.
