grinder operators of safety and protection

Safety for production, production must be safe.

Every surface grinder operator must attach great importance to safety in production, have certain knowledge of safety production and strictly abide by safety operation rules. Pay attention to the following points during operation:

1) When working, they should wear work clothes according to the regulations, and female workers should wear working caps.

2) The grinding wheel must be installed and tightened correctly. The new grinding wheel should be gently tapped on the side of the grinding wheel with a wooden mallet to hear whether the sound of the grinding wheel is clear and crisp. If the sound is mute, the grinding wheel may have cracks, and it can only be used after passing the safety rotation test; otherwise, the grinding wheel shall be scrapped. Check that the circumferential speed of the grinding wheel does not exceed the safe circumferential speed of the grinding wheel. When the new grinding wheel is replaced, the grinding wheel must be balanced. After the first dressing, the grinding wheel balance should be balanced again.

3) The storage period of resin and rubber bonded grinding wheel is 1 year. If the storage period exceeds the storage period, it must be re inspected before use.

4) The grinding wheel of various surface grinder must be equipped with protective cover, and grinding without protective cover is not allowed. Before grinding, the grinding wheel should be idle for 5min. When starting the grinding wheel, people should not stand in front of the grinding wheel.

5) Before grinding, carefully check whether the workpiece clamping is correct. Surface grinding machine to check whether the magnetic table suction is reliable, in grinding narrow and high workpiece, the front and back of the workpiece should be placed stop iron.

6) Before driving, the position of reversing block must be adjusted and tightened. When the worktable is feeding automatically, the collision between the grinding wheel and the shoulder of the workpiece, chuck or chuck should be avoided.

7) When measuring the dimension without stopping the grinding wheel, the grinding wheel should be withdrawn quickly to prevent the grinding wheel from damaging the hand or measuring tool.

8) When machining the discontinuous surface, the feed rate should not be too large to prevent the workpiece from flying out to hurt people.

9) It is forbidden to use the end face of general grinding wheel to grind a wide plane; it is forbidden to grind curved workpiece on Centerless Grinder.

10) After the workpiece is processed, the grinding wheel must be retreated to a safe position before the workpiece can be loaded and unloaded. At the end of the work, the grinding wheel should be allowed to idle for 5 minutes before turning off the power supply of the grinding wheel.

11) All exposed rotating parts on the surface grinder shall be protected by a cover.

12) Attention must be focused during operation, and illegal operation such as leaving the machine tool is not allowed.

13) Pay attention to the safe use of electricity. In case of electrical failure, electricians should be asked to check and repair. Surface grinder operators should not open the electrical box and tamper with electrical equipment.

14) The working site shall be kept clean and tidy, and the production shall be civilized.

15) Pay attention to fire prevention in production workshop.
