Nowadays, industrial development is much faster, and the mechanical products are processed, such as the processing of some equipment casings, the cutting of steel, etc. At this time, the most used is the 14 inches cutting disc. The grinding wheel cutting piece requires the material to be hard, wear-resistant and cut. Fast speed, long-lasting use, the most used is the resin grinding wheel cutting sheet. But when cutting different materials, you need to use different cutting pieces. Now the experts introduce the technique of selecting the grinding wheel cutting piece. Selecting the grinding wheel cutting piece is the first thing to observe. The good uniformity appearance and no crack shape are the basic appearances of the high quality grinding wheel piece; the lower the static unbalance value of any grinding wheel piece, the better the production difficulty; of course, the cutting and polishing The general rule is that the amount of iron to be removed is small, the wear is low, the grinding wheel is too hard, the amount of iron to be removed is too large, the material is too poor, the quality of the inner quality is as little as possible, the maximum amount of iron is removed, and the hand feels good; Cutting carbon steel, stainless steel profiles (non-solid) require the use of a higher hardness of the grinding wheel will greatly improve the life. Due to the rapid development of the processing industry, many steel and industrial products need to be reprocessed, which has led to the development of the cutting sheet industry, which has high requirements on the performance, material, use time, sharpness and adhesion of the cutting sheet. And after research and innovation, the new grinding wheel ultra-thin performance is better. Through data analysis and research, experts talk about the grinding wheel ultra-thin installation requirements. The research shows that before installing the high quality cutting disc supplier, it is necessary to check the marking of the cutting piece. The grinding wheel with unclear or no marking must be re-tested by the rotation. Otherwise, it is easy to be confused. It is necessary to understand the working line speed of the ultra-thin cutting piece. If a cutting piece with a working line speed of 50 m/s is attached to a machine with a working line speed of 80 m/s, it is easy to break. Before installation, tap the cutting piece with a wooden hammer. If a crisp sound is heard, Ultra-thin cutting blades are qualified, otherwise, there may be cracks in the grinding wheel. This grinding wheel cannot be used.
