Hybrid bearing structure type and Precautions

1, the depth of the cavity structure of hydrodynamic bearings: light load for high-speed machine tool spindles, such as M1432 cylindrical grinding, MGA6025 tool grinding.

2-hole torus throttle chamber depth Hybrid Bearing: Suitable for medium-speed machine tool spindle contained, such as MG1432 cylindrical grinding, MM7150 flat grinding, M1080 centerless grinding, roll grinding.

3, dowel pin type internal feedback hydrodynamic bearings: load and speed variations for a large range of machine tool spindles.

4, conical hydrostatic bearing: inner circle suitable for high speed grinding spindle system (such as the 2110 inner circle grinding), spindle, and the inner channel grinder.

Precautions

1, the normal use should be replaced after one year # 2 spindle oil and coarse and fine filter.

2, the normal use when the oil pump to add 3-layer silk cloth must be filtered to join.

3, the spindle pulley, wheel loading and unloading work must be in a state where the pumping station. That the spindle hydrostatic oil floating state. This does not damage the shaft and hydrodynamic bearings.

4, before work observation wheel spindle grinding hydrostatic pressure and pumping stations are within specifications.

5, equipment downtime, we must first stopped grinding motor until wheel completely stopped, then turn off the pump, or easy to damage the grinding head.

6, for any component on the pump, be sure to remove high-pressure inlet hose fittings, finished parts replacement after self-cycle oil for 15-20 minutes before the inlet pipe connected to the grinding head, thus ensuring enter the grinding spindle oil is filtered through the fine ultra-clean spindle oil. This can extend the life of the hybrid spindle.
