What environmental issues should be paid attention to when polishing
Everyone has a responsibility to protect the environment. In the grinding and polishing industry, it is important to be environment friendly.

At present, what are the environmental problems of grinding and polishing machines?
1. Many accessories on the grinding and polishing machine not recycle, such as: grinding wheels, grinding fluid, ceramic rings, etc., which contain precious mineral resources. Grinding wheels generally contain copper, iron, aluminum, diamond, etc .; grinding fluids contain certain rare earth materials such as cerium dioxide or silicon dioxide; ceramic rings are made of ceramics. Because these things can only be eliminated after they are used up, they cannot be reused, caused waste.
2. Trace active acidic liquids in liquids such as polishing liquids. It is easy to volatilize during the grinding process and pollute the atmosphere. Although it is very small, it also exists.
3. During the grinding the workpiece process, the particles and grinding fluid generated during the grinding of the disc and the workpiece are mixed together to produce contaminated garbage. At present, this garbage is directly discharged, and there is no environment-friendly discharge location and method.

How to solve the non-environmental factors?
1. For metal solid parts such as grinding wheels, new processing technology should be developed to strive for waste utilization and avoid mineral resources waste.
2. The process of polishing fluid flowing from the bottle into the grinding disc is automatically sealed, or a purification device is added to purify the emitted gas in the sealed device without polluting the air. The other is to update the formula of the polishing liquid to replace a small amount of unstable gas with a harmless liquid.
3. Government support. Arrange a reasonable sewage discharge place or provide advanced sewage treatment equipment.
