Vitrified diamond grinding wheels have the advantages of high hardness, strong wear resistance, good stability, etc., which can effectively improve processing accuracy and surface quality. Its unique vitrified bond structure makes the grinding wheel have strong anti-deformation ability at high temperature, which is suitable for high-speed grinding and processing of difficult-to-process materials. It is widely used in the precision processing of hard and brittle materials such as PCD CBN, cemented carbide, metal ceramics, etc.
Recently, we have received negative feedback regarding Moresuperhard vitrified bond peripheral grinding wheels.Customers report that the grinding wheel is consumed too quickly. In the past, it was necessary to re-cut after grinding two pieces. Now, it is necessary to re-cut after grinding less than one piece. According to the analysis of Moresuperhard' engineers, the customer used a ceramic diamond grinding wheel manufactured at low room temperature. When the temperature was too low, the temperature sensor of the grinding wheel sintering furnace would be insensitive, resulting in insufficient sintering strength of the grinding wheel and the grinding wheel being too soft.
1.Effect of temperature and humidity changes on raw materials During the production process of ceramic diamond grinding wheels, raw materials such as diamonds and binders need to strictly control humidity and temperature. Excessive humidity may cause raw materials to absorb moisture, affecting the bonding strength and hardness of the grinding wheel; while excessive temperature may cause volatilization or unstable quality of certain materials, thus affecting the overall performance of the grinding wheel.
2.Effect of humidity on binders
Ceramic binders are usually made of raw materials such as clay, quartz, and feldspar through high-temperature sintering, and these materials are sensitive to humidity. Excessive humidity may make the binder composition unstable, affect the molding accuracy and sintering quality during the sintering process, and cause uneven structure and hardness of the grinding wheel.
The impact of low temperature environment on the production of vitrified diamond grinding wheels: Low temperature weather may cause the bonding performance of certain binders and diamonds to decline, affecting the bonding strength and wear resistance of the grinding wheel. Especially in low temperature environments, the sintering process of vitrified diamond grinding wheels may take longer or uneven sintering may occur, thus affecting the overall quality of the grinding wheel.
Vitrified diamond grinding wheels have certain requirements for the storage environment, especially temperature and humidity changes. If the storage environment is unstable, the grinding wheel may be affected by moisture, temperature changes or other factors, resulting in degradation of the performance of the bond or diamond. Therefore, using the grinding wheel as soon as possible can reduce the negative impact of the environment on its performance. The diamond abrasive grains in the vitrified bond diamond grinding wheel are firmly fixed by the vitrified binder. If the grinding wheel is stored for a long time, the binder may become more brittle or loose due to changes in the environment, resulting in the shedding of diamond abrasive grains or the degradation of wear performance. Using it as soon as possible can minimize the shedding of diamonds and maintain the grinding efficiency and effect of the grinding wheel.
