Maintenance and maintenance of spindle components

The main shaft component is an important part of the CNC machine tool, which is mainly composed of the main shaft, bearing, spindle stop device, automatic clamping and chip removal device.

The lubrication, cooling and sealing of the spindle parts of CNC machine tools are important problems in the process of machine tool use and maintenance.

First of all, good lubrication and effect can reduce the working temperature and extend the service life of the bearing. Therefore, in operation and use should pay attention to: at low speed, use grease and oil for circulation lubrication; High speed oil mist and oil lubrication. However, when using grease lubrication, the sealing amount of the spindle bearing is usually 10% of the volume of the bearing space, and it is strictly prohibited to fill it at will, because too much grease will aggravate the heat of the spindle. Oil circulation lubrication, check the spindle lubricating constant temperature tank every day to see if the oil is sufficient. If the amount of oil is insufficient, add lubricating oil in time. At the same time, pay attention to check whether the temperature range of the lubricating oil is appropriate.

In order to ensure the good lubrication of the spindle, reduce friction and heat, while taking away the heat of the spindle assembly, the circulation lubrication system is usually used, and the oil temperature controller controls the oil temperature in the tank. The spindle bearing of the high-end CNC machine tool is lubricated by the high-grade grease reservoir, which can be used for 7 to 10 years each time the grease is added. The new lubrication and cooling method not only reduces the temperature rise of the bearing, but also reduces the temperature difference between the inner and outer rings of the bearing to ensure that the thermal deformation of the spindle is small.

There are two common methods of spindle lubrication. Oil and gas lubrication is similar to oil mist lubrication, but oil mist lubrication is a continuous supply of oil mist, and oil and gas lubrication is a regular quantitative oil mist into the bearing gap, which not only realizes oil mist lubrication, but also avoids excessive oil mist pollution to the surrounding air. Spray lubrication method is to spray a large flow of constant temperature oil (3 to 4 L/min per bearing) to the main shaft bearing for lubrication and cooling. Here, the large flow of injected oil must be forced out by the pump, rather than natural backflow. At the same time, a special large-capacity, high-precision constant temperature tank should be used, and the oil temperature change should be controlled at 0.5.

Secondly, the cooling of the spindle components is mainly to reduce the bearing heat and effectively control the heat source.

Third, the sealing of the spindle components should not only prevent dust, debris and cutting fluid from entering the spindle components, but also prevent oil leakage. The sealing of spindle components includes contact sealing and non-contact sealing. For the contact seal of the linoleum ring and the oil-resistant rubber seal ring, pay attention to check its aging and damage; For non-contact seals, in order to prevent leakage, it is important to ensure that the return oil can be discharged as soon as possible and the return oil hole is smooth.
