The cutting discs belong to the grinding wheel and is made of abrasive and binder resin. For cutting thin sheets of ordinary steel, stainless steel and non-metallic materials. Divided into resin cutting disc, diamond cutting disc.
The cutting disc is broken and cannot be used. This phenomenon occurs when the operation is not standardized during production. So we need to understand the factors that lead to this phenomenon. In the future production process, special attention can be paid to reduce the occurrence of this phenomenon. What are the factors?
1. The cutting disc is an inferior product, and it does not reach the line speed of the cutting table.
2. In addition, the hole diameter of the cutting disc and the shaft of the cutting discs are not equipped, and there is a large stress during assembly.
3. When the tissue of the cutting disc is uneven. With the cutting process torque force, thermal stress, chatter and other factors. Stress can build up where the tissue is weak, leading to rupture.
4. When the hardness of the cutting piece is too high. Radial torque forces on the cutting disc are increased. Since the thickness of the cutting disc is usually less than 4mm, it will cause the cutting disc to break.
5. When the cutting disc resin lacks toughness. Since the grinding wheel is always under negative pressure during the cutting process, lateral stress is inevitably generated. Disc rupture occurs when the cutting disc cannot resist the lateral force.
The above five factors will lead to the phenomenon of rupture of the cutting disc. It can be seen that the details are not handled well, which will lead to this phenomenon. Once broken, it will be unusable and wasteful. You can refer to the above factors in subsequent production to reduce the phenomenon of broken.
