1. Torch collision. For non-contact seals, it is necessary to ensure that the return oil can be drained as soon as possible and the oil return holes are unobstructed; for contact seals, pay attention to check its aging and damage. Therefore it is widely used.
2. Destructive plasma arc due to damage to consumables.
3. Cooling of spindle components
The main purpose of cooling the main shaft components is to reduce the bearing fever and effectively control the heat source.
4. Do not use the manual torch as a hammer. Therefore, it is necessary to select an appropriate capacity when adding lubricating grease.
5. Do not apply grease to the torch. The recirculating lubrication system is lubricated with hydraulic pump for strong oil supply, and the oil temperature controller is used to control the oil temperature of the oil tank.
6. Lubrication of spindle components
The lubrication of the spindle components is to reduce the operating temperature of the bearing and prolong the service life.
7. Destructive plasma arc caused by dirt.
8. Destructive plasma arc caused by loose parts.
The recirculating lubrication system can not only ensure good lubrication effect, reduce friction and fever, but also take away the heat of the spindle assembly. Generally speaking, grease and oil circulation lubrication is used at low speed; oil mist and oil-air lubrication are used at high speed.
In order to prevent the occurrence of the above problems, it is necessary to pay attention to the use of the CNC cutting machine.
(1) Do not overuse the O-ring lubricant. But it is worth noting that too much oil can easily aggravate the spindle fever.
(2) Do not spray anti-splash chemicals while the protective sleeve is still on the torch.
9. Sealing of spindle components
The seals of the spindle components are non-contact and contact seals.
