Aluminum alloy sawing process

Aluminum plates will inevitably produce fission edges during the production process. In order to provide users with medium and thick aluminum plates with precise sizes aluminum alloy thick plates must be sawed.
Pay attention to the following points when sawing:
1. The aluminum plates to be sawed must be sawed at room temperature, and the saw blades must be lubricated with sufficient emulsion or lubricating oil when sawing.
2. Before chopping, check the process records. Unqualified aluminum plates should be picked out when chopping.
3. When chopping, the debris on the plate surface should be removed in time to avoid marks. The sequence number should be written on each plate, and sawing markings should be drawn on the side to ensure that the defective parts are removed. 4. When sawing in piles
, special clamps should be used to clamp to prevent the aluminum plates from moving. When sawing quenched and stretched plates, the dead zone near the jaws should be cut symmetrically, and about 200 mm or more outside the shallow mouth should be sawed on each side. 5. The equipment operator
is responsible for sawing and cutting the fixed length, and the designated person is responsible for re-sizing. After confirmation, sawing can begin. The sawing speed can be appropriately selected according to the alloy and thickness. Generally, it is 0.5 meters per minute or 1 meter per minute.
6. For aluminum plates that need to be trimmed before quenching or stretching due to edge defects, if the width margin allows, a margin for the second sawing should be left.
7. If the size cannot be guaranteed due to dark cracks on the edge of the aluminum plate, it should be handled in accordance with the relevant regulations for unqualified products.
8. Cut the sample according to the sampling regulations and mark it well.

9. The actual size and appearance quality of the saw edge of the aluminum plate after sawing should meet the requirements of the internal quality control standards. The production personnel are responsible for marking the alloy grade, batch number, status, specifications, etc. on the material stack.
10. The scraper and inlet should be fully unobstructed. No other materials are allowed to be stored except for the scraps. Waste scraps should be removed in time during production.
11. When sawing, the sawing feed should be properly controlled to ensure that the sawing surface is smooth, without burrs, and the sawing knife marks do not exceed 0.5 mm.
12. After sawing, the emulsion, scraps and other debris on the aluminum plate should be wiped clean. 13. It is strictly forbidden to saw the bite part before stretching and the quenched aluminum plate that has not been stretched and has high stress.
14. In order to ensure the accuracy of the equipment and the quality of the product, it is forbidden to use saw blades and wood squares that do not meet the specified requirements.
15. When the saw blade sticks to aluminum, loses teeth or other problems occur, the machine must be stopped and handled in time to ensure that the sawing machine is in good working condition.
16. After sawing, the saw head should be parked at the highest position at either end of the beam frame.
