Grinding wheel cutting disc refers to a thin sheet made of abrasive and separating agent resin for cutting popular steel, stainless steel metal and non-metallic materials. It mainly uses glass fiber and resin to strengthen the separation material, which has high tensile, impact and Because of its unique flexural strength, it is widely used in the production of popular steel, stainless steel and non-metallic materials.
Grinding wheel cutting discs use resin as a separating agent, blending glass fiber mesh and a variety of materials, which can complete the cutting of alloy steel, stainless steel and other strong materials. The function is very obvious, and the cutting accuracy is not chaotic, which can greatly improve the cutting efficiency, Frugal and productive.
The reasons for the occurrence of film on the cutting wheel of the grinding wheel may be as follows:
1. Out of the furnace or out of the kiln is too rapid or the temperature difference is too large.
Since the cutting blade should have a certain cooling time period to satisfy the average release of the stress at the end of the hardening and heat preservation, if the temperature of the furnace is too high or the temperature difference is too large, the cooling changes of the grinding wheel will not be synchronized, and the deformation of the grinding wheel will appear.
2. Relieve the problem of hardening humid atmosphere in the hardening furnace.
Whether all hardening furnaces are box-type furnaces or tunnel kilns, air intake and exhaust must be considered when planning the furnace. Since a small amount of exhaust gas may be released during the hardening process (primarily only ammonia and water vapor), if these exhaust gases cannot be squeezed out in real time, they will be re-adsorbed by the pores during the cooling process, which will cause the grinding wheel to odor and soften.
3. The hardening temperature is unstable.
It means that due to the double influence of the situation and the raw materials, when the temperature and humidity change greatly, the curing temperature will be supplied in real time. The high hardening temperature means that the hardening curve has been adjusted, but when the temperature drops and the weather is boring, the hardening stability is not lowered in real time, and it is also simply caused by the cutting film.
4. The time to harden the curve is short.
This mainly means that under certain conditions, the high temperature and dry time of the hardening curve is short, and the heating rate is too fast during the heating stage.
