In this paper, the main raw materials are phenolic resin and glass fiber mesh how to affect the quality and stability of resin 4.5 inches grinding wheel is analyzed.
The quality and stability of resin wheel are mainly manifested in the following two aspects:
(1) Change of strength and cutting and grinding performance of resin depressed grinding disc in stocks during a certain period (under normal air temperature and humidity);
(2) The strength and cutting and grinding performance of resin low price grinding discs in each batch during the production cycle (e.g. in different seasons of a year).
The above two conditions can be expressed by the measured strength retention rate and the reduction rate of tangential grinding performance.
