This article delves into the application of UHD's brazed diamond grinding wheels in automotive parts processing by Henan UHD Superhard Tools Co., Ltd. It specifically analyzes how brazing technology enhances the wear - resistance and impact - resistance of grinding wheels, addressing industry pain points such as frequent chipping of grinding wheels during gray cast iron processing.
The brazing process in diamond grinding wheels is a complex yet crucial technology. The principle of brazing technology lies in the use of active filler metals. These filler metals can react with diamond and the substrate at high temperatures, forming a strong chemical bond at the interface. For example, in the brazing process, the active elements in the filler metal, such as titanium (Ti), can react with carbon in the diamond to form titanium carbide (TiC), which significantly improves the bonding strength between the diamond and the substrate. According to industry research, the interface bonding strength formed by brazing can reach up to 80 - 100 MPa, while the traditional bonding method is only about 20 - 30 MPa.
In terms of process operation, the brazing process involves precise temperature control and the selection of appropriate filler metals. The brazing temperature usually ranges from 800 - 1000°C. If the temperature is too low, the reaction between the filler metal and the diamond will be incomplete, resulting in poor bonding strength. If the temperature is too high, the diamond may be graphitized, reducing its performance. Compared with traditional bonding methods, brazed diamond grinding wheels have significant advantages in wear - resistance and impact - resistance. In a wear test, brazed grinding wheels can maintain their cutting performance for up to 50 - 60 hours, while traditional grinding wheels can only last for about 10 - 15 hours.
In a real automotive parts factory, the application of UHD's brazed diamond grinding wheels has brought remarkable improvements. For instance, in the processing of engine cylinder blocks, the use of brazed grinding wheels has increased the processing efficiency by 30 - 40%. At the same time, due to the improved wear - resistance and impact - resistance, the safety of the processing process has also been enhanced, reducing the frequency of accidents caused by grinding wheel breakage.
By fine - tuning processes such as brazing temperature control and diamond distribution density, the adaptability of grinding wheels to extreme conditions can be improved. For example, increasing the diamond distribution density can improve the grinding efficiency and wear - resistance of the grinding wheel in high - load processing environments. Adjusting the brazing temperature can optimize the interface bonding strength, making the grinding wheel more suitable for high - speed processing.
