Grinding is widely used and is one of the first methods for fine machining of machine parts. Tool grinders are also commonly used for grinding wheels.
However, because the speed of the tool grinding wheel is high, the grinding wheel is relatively hard, brittle, and cannot withstand heavy impacts. Occasionally improper operation can cause very serious results when the wheel is broken.
Therefore, the safety and technical work of tool grinding machines are particularly important. Must adopt reliable safety protection equipment, and must focus and ensure the operation.
In addition, the fine sand and metal chips splashed on the workpiece of the grinding wheel during the grinding will hurt the workers' eyes. If workers inhale this dust in large quantities, it will be harmful to the body and should adopt appropriate protective measures.
Safety technology of tool grinding machine processing
should pay attention to the following safety technical issues when grinding.
1. Before starting the machine, you should carefully inspect the machine tool. Including the operating mechanism, electrical equipment, and magnetic chucks.
2. After checking, smooth it again, and then test run it before use. Pay attention to the clamping and clamping when installing the workpiece. During the grinding process, the loosening of the workpiece will cause serious results such as flying out of the workpiece or hurting the grinding wheel.
3. When turning on the machine, use the manual adjustment method to make the grinding wheel close to the workpiece slowly, and the feeding amount at the beginning should small. Do not use excessive force to avoid bumping the grinding wheel.
4. When you need to use the stopper to control the reciprocating motion of the table, adjust it accurately according to the grinding length of the workpiece, and tighten the stopper firmly.
5. When replacing the grinding wheel, you must first check the appearance to see if there is any trauma, and then hit it with a wooden hammer or stick. The sound is crisp and no cracks are required.
6. When installing the grinding wheel, it must be assembled in accordance with the prescribed methods and requirements. After the static balance debugging, we should install and test the device. Only after all are normal, and can use it.
7. Workers should wear protective glasses during work. They should balance the grinding wheel to avoid a collision. Workpiece measurements, adjustments, or scrubbing of the machine are performed after shutdown.
8. When using a magnetic suction cup, wipe the disk surface, the workpiece clean, tight, and stuck firmly. If necessary, you can add an iron stop to prevent the workpiece from shifting or flying out.
9. Attention should be paid to the installation of the wheel guard or the machine baffle, and the station should pass the front side of the high-speed rotating wheel.
