Non-standard bearing manufacturing smelting purity requirements and matters needing attention

Non-standard bearing manufacturing source of smelting purity requirements and matters needing attention: bearing | last updated: - 2020 09 - 16 a special non-standard bearing steel smelting strictly the purity requirements of steel purity refers to contain nonmetallic inclusion in steel, the higher the purity, the less the non-metallic inclusions in steel. Non-standard bearings harmful oxide and silicate inclusions in steel is non-standard bearing early fatigue spalling, significantly reduced the main cause of non-standard bearing life. Especially brittle inclusion most harmful, because in the process of peeling off easily from the metal substrate, the serious influence of non-standard bearing parts surface quality after finishing. Therefore, in order to improve the service life and reliability of non-standard bearings, must reduce non-standard bearing the content of inclusions in steel. The use of non-standard bearing note 1. Normal use after one year should replace 2 # spindle oil and coarse fine filter. 2. Normal using pump station to make up for the oil must be 3 layer filter for silk cloth. 3. When spindle pulley, wheel loading and unloading must be under the conditions of pumping station operation. The spindle under the conditions of static pressure oil float. So don't damage the spindle and dynamic pressure bearing. 4. Grinding wheel spindle survey 'before the pump pressure and the grinding head can static pressure in a standard size. 5. Equipment mainly; Must be stopped first grinding head motor; After waiting for grinding wheel stopped; To turn off the pump station; Or simple grinding head injury. 6. In the pump station of any components. Must first removing the high pressure oil inlet hose connection; After replacing the parts; Rear oil loop of 15 ∽ 20 minutes into the tubing can be connected to grinding head; Thus ensure the into the grinding head spindle oil is super clean spindle oil through fine filtering. Doing so can extend the use of dynamic pressure spindle longevity.
