1, deep and shallow cavity layout dynamic pressure bearing: suitable for high-speed light-load machine tool spindle; such as M1432 cylindrical grinding, MGA6025 things grinding and so on. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
2, hole type torus to save deep and shallow cavity dynamic pressure bearing: suitable for medium speed medium load machine tool spindle; such as MG1432 cylindrical grinding, roll grinding, etc.
3. Pin-type internal reaction dynamic pressure bearing: suitable for machine tool spindle with large load and speed change.
4. Conical hydrostatic bearing: suitable for high-speed internal grinding head spindle system (such as 2110 inner grinding head), electric spindle, and inner channel grinding machine.
Application notes:
1. Replace the 2# spindle oil and coarse fine filter after one year of normal operation.
2, the normal use of the pump station to make up for the oil must be 3 layers of silk cloth filter to participate.
3. When the spindle pulley and the grinding wheel are loaded and unloaded, it must be carried out under the condition of the pump station operation. That is, the spindle is carried out under the condition that the static pressure oil floats. This does not damage the spindle and the dynamic pressure bearing.
4. Before the operation of the grinding wheel spindle, investigate whether the pressure of the pumping station and the static pressure of the grinding head can be within the standard scale.
5, the equipment is stopped; must first stop the grinding head motor; after the grinding wheel is stabilized; then turn off the pump station; otherwise simply damage the grinding head.
6. Change any parts on the pumping station; must first remove the high-pressure oil inlet hose joint; after replacing the parts; the oil circuit can be self-circulated for 15-20 minutes before the oil inlet pipe can be connected to the grinding head; this ensures The spindle oil entering the grinding head is an ultra-clean spindle oil that is finely filtered.
