How to use resin cutting sheet

The resin cutting piece as a sharpening tool must pay attention to the operation specification when it is used, otherwise, it will be prone to accidents. So what can be considered as its standard method of use? 1. When using the thin abrasive cutting disc for metal, first observe the safety rules of GB2494 abrasives; 2. The cutting piece is only allowed to be used for single piece installation. It is strictly forbidden to install two or more pieces at the same time; 3. The speed of use of the cutting piece shall not exceed the working line speed specified by the trademark of the cutting piece. When using a pneumatic grinding machine, the air pressure shall be prevented from being unstable, resulting in the cutting piece exceeding the maximum speed; 4. The storage time of the resin cutting piece is one year. If the time exceeds the time, the rotary inspection should be carried out again. 5. When using the cutting piece, it is necessary to make a sudden push. If the force is too strong, it will easily stop. If the jam occurs, the cutting piece should be caught. If the jam occurs, the cutting piece should be lifted immediately to prevent the cutting piece from burning out or being broken. The grinding wheel is a fixed abrasive which is fixed by a bonding agent into a certain shape (mostly circular, with a through a hole in the center) and has a certain strength. It is generally composed of abrasive, bonding agent and pores. It is called the three elements of the fixed abrasive. The grinding wheel is the largest amount in the grinding tool. It is the most widely used one. It can be rotated at high speed during use. It can be used for the outer circle of metal or non-metal workpiece. Inner circle, plane and various types. Rough grinding, semi-finishing, and fine grinding, and slotting and cutting. Matters needing attention during the use of the grinding wheel: 1. When using the flat grinding wheel, be sure to first idling for 2~3 minutes before use, and it is forbidden to use it. 2. The bolt-fastened grinding wheel should ensure the flatness of the grinding wheel when it is used, and there is no attachment between the grinding wheel and the middle plate of the grinding wheel to avoid cracking during the use of the grinding wheel. The causes and hazards of the grinding wheel forming a wave-shaped grinding surface during use: Due to the uneven mixing of the grinding wheel during the mixing process, the internal structure of the standard cut off wheel for metal is uneven, and the bonding agent is not well adhered. Due to the inconsistency of the grinding wheel in the grinding process, the corrugated grinding surface is formed, which directly affects the verticality of the grinding workpiece and Flatness.
