Operators must receive training on this equipment before starting work, including safety operation, equipment calibration, quality identification, work discipline, etc; The specific content and implementation are the responsibility of the production workshop and team. After passing the training, the equipment, preparation work, and site requirements can only be officially operated with the recommendation of the team leader and the approval of the workshop supervisor.
1、 Pre startup inspection:
1. Is the power switch in good contact.
2. Are there any foreign objects, bolts, belts, or loose connections on the machine tool; Whether the feeding, guiding, and polishing wheels are rotating normally, and whether all components are clean.
3. Whether the selection of polishing wheels and the spacing between each wheel match the specifications and shape of the material to be processed.
4. Inspect the processed materials for any deformation, severe scratches, or other issues.
5. Is there any disorderly stacking or placement in the work area, and are there any safety hazards.
6. Protective measures, such as opening the exhaust fan, wearing a mask, and not allowing people to stand in the direction of the discharge outlet.
2、 Power on operation
Firstly, start the feeding wheel and adjust the speed from slow to fast to the green area on the tachometer. After running steadily for 3-5 minutes, adjust the speed to slow (2-4 grids from the left) and observe whether the material maintains a linear motion between each wheel. Adjust the tightness of the contact between each wheel and the material appropriately. Rotate the polishing wheel by hand, check the tightness of the contact between each position on the circumference and the material, and adjust it to a lighter contact state. After all the wheels are calibrated, start the polishing wheel and run it for 3-5 minutes. After the bed runs smoothly, wax the polishing wheel and start the material feeding process.
Attention: During the processing, it is necessary to constantly observe whether there are any deformation, burns, scratches, brightness and other issues during the polishing process of the material. When problems are discovered, the machine should be stopped in a timely manner for corresponding calibration. When the problem cannot be identified clearly or cannot be solved by calibration, it should be reported to the workshop and other departments in a timely manner for processing and solutions.
3、 Requirements after shutdown:
1. All power switches must be turned off.
2. Clean the dust on the machine tool and various components; Clean up the site hygiene; The materials are neatly arranged.
4、 Track adjustment
Due to the different specifications and shapes of the materials, it is necessary to adjust the wheelbase.
1. Adjustment of feeding wheel and guide wheel. Each adjustment should be made on the same side, keeping the other wheel stationary as much as possible, in order to ensure that each adjustment of each set of wheels can be on the same straight line. Each adjustment should be loosened gradually until the appropriate tightness is reached. The polishing wheel should be in the closed state at this time.
2. The adjustment of the polishing wheel should be based on the size and shape of the material before each adjustment. If it does not match or has been deformed, the polishing wheel must be ground to match the size and shape of the material before adjustment (only waste materials are allowed during grinding). The adjustment of the polishing wheel is affected by changes in the external dimensions, and both wheels must be adjusted. Adjust first and then tighten until mild contact is reached.
Caution: Do not change the straight direction of material travel. The polishing process requires frequent waxing of the polishing wheel to avoid reducing the polishing effect due to surface roughness.
