Understand the process and precautions for starting the grinding wheel of the cylindrical grinder each time.
1. Before starting the grinding wheel each time, the hydraulic on-off valve should be placed in the stop position, the adjustment handle should be placed in the low-speed position, and the grinding wheel seat feed handle should be placed in the reverse position to avoid accidents.
2. Before starting the grinding wheel, the lubrication pump of the external cylindrical grinder or the oil pump of the static pressure oil supply system should be started first, and the grinding wheel can only be started after the lubrication of the grinding wheel spindle is normal.
3. At the beginning of grinding, the feed rate should be small and the cutting speed should be slow to prevent the grinding wheel from breaking due to cold brittleness, especially in winter when the temperature is low.
4. Before starting grinding, the distance between the grinding wheel and the workpiece should be adjusted to avoid collision between the grinding wheel and the workpiece when the grinding wheel seat is close. When the grinding wheel is close to the workpiece, it is not allowed to move the feed or use a large knife. Pay attention to the protruding corners of the workpiece to avoid collision.
5. When the temperature of the grinding wheel spindle of the external cylindrical grinder exceeds 60 ℃, the equipment must be turned off and the temperature should be restored to normal before resuming operation.
6. After work, the cooling pump should be turned off, and the grinding wheel should run idle for a few minutes to shake off the coolant before turning off the grinding wheel.
7. Before use, check if the oil injector for the guide rail of the cylindrical grinder is working properly.
8. When correcting the grinding wheel, the grinding wheel seat should be introduced before carrying out the grinding wheel correction work.
9. Before starting the grinding wheel of the cylindrical grinder, the reversing handle must be placed in the position where the grinding wheel moves away from the workpiece to avoid accidents.
