As we all know, the [url= https://www.auroraabrasive.com/115-mm-go...r-cutting-disc/]4 1/2 super thin cutting disc [/url] is the most important type of grinding tool in the grinding process. The cutting piece is a porous body made by adding a binder to the abrasive, pressing, drying and roasting. Due to the abrasive. Different bonding agents and manufacturing processes, the characteristics of the grinding wheel are very different, so it has an important influence on the processing quality, productivity and economy of the grinding. The characteristics of the grinding wheel are mainly composed of abrasive, strength, bonding agent, hardness, organization, shape and size. Other factors determine.
The use of 4 1/2 super thin cutting disc is:
Due to the intense friction, the temperature in the grinding zone is very high. This causes stress and deformation of the workpiece and even burns the surface of the workpiece. Therefore, a large amount of coolant must be injected during grinding to reduce the grinding temperature. The coolant can also be used. Chip removal and lubrication.
The radial force during grinding is very large. This will cause the elastic retraction of the machine tool-grinding wheel-workpiece system, so that the actual depth of cut is less than the nominal depth of cut. Therefore, when the grinding is to be completed, the grinding should be performed without the knife to eliminate the error. After the abrasive grain is blunt, the grinding force also increases. The abrasive grain breaks or falls off, and the sharp edge is re-exposed. This characteristic is called self-sharpness. The self-sharpening makes the grinding work normally in a certain period of time. However, after a certain working time, manual dressing should be carried out to avoid vibration, noise and damage to the surface quality of the workpiece.
