Taiwan CNC vertical latheMainly used for large parts, the spindle is vertical. The worktable adopts dynamic pressure guide rail, and the spindle adopts double-row cylindrical roller bearings in the radial direction. The worktable has large bearing capacity and high rotation accuracy. The vertical tool holder is equipped with a pentagonal tool holder, the side tool holder is equipped with a square tool holder and two tool holders, all tool holders are hydraulically balanced.
When using Taiwan CNC vertical lathe, we usually also pay attention to the maintenance and maintenance of the CNC vertical lathe, so that the vertical lathe can be used for a long time without affecting the processing and production efficiency. The following vertical lathe manufacturers will analyze some Taiwan vertical lathe for you. Maintenance of lathe control system maintenance.
Taiwan CNC vertical latheThere will be noise when it stops, and the main power supply of the workshop will trip at the same time
First, check the inspection of the power system by the workshop electrician. The position of the tripped automatic air circuit breaker is corroded due to the humidity in the switch box. In addition, there is only a small part of the three-phase contacts. Secondly, the capacity of the workshop power transformer is small and overloaded.
Taiwan CNC vertical latheOne of the thyristors has been burned out. Check the drive circuit to see if the B- phase trigger pulse is short, which is only a 1/4 of the normal trigger pulse amplitude, further confirming that the amplifier tube T3 in the B- phase trigger circuit is not working properly.
Taiwan CNC vertical latheThe results of phase loss in the rectified state of the thyristor and phase loss in the inverter state are different, but if it is during parking and deceleration, that is, in the case of the inverter, the thyristor with the higher trigger potential will also turn on, and the previous thyristor will withstand back pressure and turn off. At this time, there will be problems when the thyristor is turned off, and it will be in a positive blocking state for a long time.
If the voltage supply system in the workshop is normal and does not fluctuate much, the thyristor may not burn out. The AC power grid voltage fluctuates greatly, the workshop transformer capacity is small, overload operation, the B- phase positive group trigger pulse amplitude is small, and the workshop power main switch box is damaged to cause this fault.
