|Title||Cutting disc machine polishing castings pouring riser operating procedures|
|Description||1. The machine is responsible for the fixed-machine system. Non-machine operators are not allowed to operate without the consent of the workshop leader. 2. Before going to work, the operator should carefully check all parts of the cutting machine: the flat cutting disc on sale should be free from damage, no serious gap, and the clamp should be secure, the belt should be tight, the protective cover should be installed in place, the bracket and the cutting disc The distance between the blades should be adjusted to the proper position, the exhaust fan (dust) should be operated normally, and the spindle bearings should be lubricated and refueled to ensure normal, reliable and safe production. 3. Before starting the cutting machine, check that there is no foreign matter on the belt, on the main shaft, between the bracket and the cutting disc, and idle for 5 minutes. The casting can be polished without any abnormality. 4. When grinding, you must wear gloves, masks, glasses and other labor protection articles, and the cuffs and corners of the clothes should be fastened to prevent the fan from floating and to ensure the safety during operation. 5. When grinding, the castings should be stabilized on the bracket plate. When the casting starts to be sanded, the pouring nozzle due to the gas cutting is not flat, and the lighter force is applied. After the surface is smoothed, the gravity can be added. However, the gravitational force should also be moderate to prevent the danger of the disk being broken due to excessive force. 6. In the grinding, it is necessary to prevent the pushing casting from being too heavy, resulting in excessive load and burning electricity. Motivation, and should often be used to touch the motor casing and the main shaft bearing housing and the cutting disc. When hot burning occurs, stop and rest to prevent the motor from being burnt and the bearing dead. 7. The amount of pouring riser after grinding shall be carried out according to the production process of the product to ensure that the quality of the casting meets the requirements. 8. On the same day (class) cutting disc grinding gate production is finished, and the cleaning and cleaning work of the equipment and production site is done well. Precautions: 1. The storage period of the resin cutting disc is one year, which is subject to the manufacturer's instructions. 2. There must be a flexible material cushion (such as asbestos, rubber sheet, cardboard, felt, leather, etc.) between the cutting disc and the flange. The thickness is 1-2 mm, and the diameter should be larger than the outer diameter of the flange. 3 mm, it is forbidden to force the cutting disc without padding.|
