A grinding wheel is a tool commonly used for grinding, cutting and polishing. The following are the production steps and process of grinding wheel:
1. Raw material preparation: The main raw materials for the production of grinding wheels are sand grains, binders and fillers. Sand particles are generally high hardness and durable mineral powders such as alumina and silicon carbide. Binders are generally resins, ceramics, etc. Fillers are used to adjust the hardness and density of the grinding wheel.
2. Mixing raw materials: Mix raw materials such as sand grains, binders, fillers and so on according to a certain proportion to form the basic material of the grinding wheel.
3. Pressing: Put the uniformly mixed base material into a pressing machine for pressing. High pressure is required to ensure the density and hardness of the grinding wheel sheet during pressing.
4. Preheating: Through high temperature preheating treatment, the structure of the grinding wheel is stronger and more durable.
5. Forming: Cut the pressed and preheated grinding wheel sheet into the required size and shape with a cutting machine. And the surface treatment is carried out to make the grinding wheel smoother when used.
6. Drying: Dry the formed grinding wheel in an oven to remove moisture.
7. Finished product inspection: The final quality inspection of the grinding wheel, including the detection of parameters such as hardness and density. Only the grinding wheel discs that pass the inspection can be sold and used.
8. Packing: Pack the quality-checked discs with appropriate packaging materials to protect them from damage during transportation and storage.
