In the use and maintenance process of the laser pipe cutting machine, great attention is paid to the lubrication, cooling and sealing of the spindle components, and carefully do this work. The following is the maintenance skills of the main shaft parts of the laser pipe cutting machine:
Sealing of spindle components: the sealing of spindle components is non-contact sealing and contact sealing. The purpose is not only to prevent the entry of dust, debris and cutting fluid, but also to prevent the leakage of lubricating oil. The non-contact seal should ensure that the oil return can be discharged as soon as possible and the oil return hole is smooth; Check contact seals for aging and damage.
Cooling of the spindle components: The main purpose of cooling the spindle components is to reduce the bearing heat and effectively control the heat source. The lubrication cycle lubrication system of the spindle components can not only ensure good lubrication effect, reduce friction heat, but also take away the heat of the spindle assembly. Therefore, it is widely used. The circulating lubrication system is lubricated by hydraulic pump, and the oil temperature controller is used to control the oil temperature in the tank.
The lubrication of spindle components is to reduce the operating temperature of bearings and extend their service life. Generally speaking, low speed grease and oil circulation lubrication is used; High speed oil mist and oil lubrication. However, it is worth noting that too much grease can easily exacerbate the heating of the spindle. Therefore, the appropriate capacity should be selected when adding grease.
