Key operating points of internal grinding machine

Operation points of internal grinding machine

1. Check whether the oil level in the oil tank and oil tank meets the hydraulic indicators<2. Check if the oil grade and material quality comply with the instructions in the user manual<3. Each operating handle (handwheel) should be placed in the closed or unloaded position, and the grinding wheel holder (grinding head) should be in the reverse position. The moving parts should not collide with each other<4. Check whether the motor of the oil pump is running normally, and then check whether the pressure of the oil circuit, auxiliary oil circuit, and lubricating oil circuit meets the requirements of the user manual. (For machine tools with unloading function requirements, the pressure of the main oil circuit should be adjusted to a lower level, and the unloading operation handle should be turned to the stop position, and then the pressure should be checked.)
5. The machine tool should open the air release valve, exhaust the air in the oil cylinder and system, and then close the air release valve
