Methods/steps

1

1. Before starting the machine, check the conditions around the machine. Nothing can be placed on the machine, and the workpieces should be placed neatly. And oil the guide rail once.

2. Before starting the machine, check whether the oil level in the oil tank is normal, whether the water level in the cooling water tank is normal, whether the clearance between the grinding wheel and the guide wheel and the supporting blade is normal, and whether there is any work or sundries in the machine tool.

3. Check whether the switch is reliable before starting, and confirm whether the safety protection such as protective cover is effective. ?

4. Turn on the power supply, start the hydraulic switch, and observe whether the hydraulic gauge pressure of the machine tool is normal. Whether the cooling fan, grinding wheel and water pump motor are connected in reverse, if so, it is necessary to adjust the incoming sequence of the live wire. Then check whether there is oil flowing through each oil mirror and each oil pipe;

5. Before starting the grinding wheel, the guide wheel must be wiped clean and the oil cup filled with oil; It is forbidden to touch the grinding wheel and guide wheel in operation by hand.

6. Before starting the machine, the operator must be trained according to the operation instructions to understand the operation process of each job.

7, untrained and inexperienced workers are not allowed to operate the machine, so as not to cause danger.

8. Please select the grinding wheel abrasive suitable for the material requirements of the workpiece to be processed. When machining the workpiece, check the consistency of the workpiece size, and the difference should not be greater than the grinding amount, otherwise it will cause danger.

9. Because the grinding wheel is relatively heavy, many people are needed to assist in installing or replacing the grinding wheel, and gloves are needed to prevent it from being scratched by the sharp water chestnut of the grinding wheel. Check the new grinding wheel carefully for damage and cracks. The damaged grinding wheel cannot be used, otherwise it will cause the danger of damage. A good grinding wheel should be idling for half an hour before it can be used.

10. Check the oil mirror of the hydraulic system. After the oil gauge is stable, recycle it for more than three minutes before starting the grinding wheel and guide wheel.

1 1. After the grinding wheel and guide wheel operate normally, turn on the water pump and adjust the appropriate water volume;

12, debugging and grinding 1-3 workpiece. Firstly, check the size and appearance of the workpiece, and put the debugging products into the debugging box;

13. When turning off the water pump motor, switch it to the off position to stop the water supply.

14, grinding wheel and guide wheel, idling continuously for more than 5 minutes, so as to spin dry water and avoid imbalance of grinding wheel when starting. After spinning dry water, switch the power supply of grinding wheel and guide wheel to OFF position;

15, after the grinding wheel and guide wheel stop, the oil pressure switch can be turned off. Don't stop the hydraulic motor first, so as to avoid oil leakage and wear the bearing bush and spindle. )

16, it is forbidden to take things above the grinding wheel and guide wheel during the operation of the machine, so as to avoid danger caused by falling objects.

17, spindle oil (10# spindle oil) and guide rail oil (68#) produced by regular manufacturers or recommended by equipment manufacturers must be selected to avoid using inferior oil to affect equipment.

Matters needing attention

You need to wear gloves to avoid being scratched by the sharp water chestnut of the grinding wheel.
