During the operation and use of diamond grinding wheels, it is necessary to pay extra attention. Usually, people often encounter the following major problems during the operation of diamond grinding wheels. Therefore, I would like to summarize the following for you, hoping to help more people understand how to operate diamond grinding wheels and what precautions need to be taken during the operation of diamond grinding wheels.

1. Side grinding:

In the daily use of grinding wheels, it is also necessary to classify them. However, many operators do not distinguish the type of grinding wheel and casually use the side surface of the grinding wheel for grinding. In order to fully play the role of diamond, it is necessary to increase the holding force of the binder on the diamond and improve the bonding strength of the grinding wheel. Single layer high-temperature brazed superhard abrasive grinding wheel can overcome the defects of electroplated grinding wheel, achieve chemical metallurgical bonding between diamond, binder, and metal matrix, and have high bonding strength. Only by maintaining the thickness of the bonding layer at 20% to 30% of the abrasive height, can the abrasive particles be firmly held in high load, high-speed, and efficient grinding. The exposed height of the abrasive particles of the brazed grinding wheel can reach 70% to 80%, thus increasing the chip holding space, Grinding wheels are not easily clogged, and the use of abrasives becomes more comprehensive.

This is a serious violation of safety operation regulations. According to regulations, using a circular surface as the working surface of a grinding wheel is not suitable for grinding on the side surface. This type of grinding wheel has a large radial strength and a small axial strength. When the operator applies too much force, it can cause the grinding wheel to break and even injure people. This behavior should be stopped in actual use.

2. Front operation:

In daily use, many operators are accustomed to operating directly against the grinding wheel. Sintered metal bonded grinding wheels are mostly made of metals such as bronze as binders using high-temperature sintering method. They have high bonding strength, good formability, high temperature resistance, good thermal conductivity and wear resistance, long service life, and can accept large loads. The reason is that force can be applied in this direction, which is actually a behavior that should be particularly stopped during grinding wheel operation. According to the operating procedures, when using a grinding wheel to grind workpieces, the operator should stand next to the diamond grinding wheel and not operate on the front of the grinding wheel to avoid injury caused by the grinding wheel flying out or breaking when the grinding wheel malfunctions.

3. Force operation:

In the application of grinding wheels, some operators have put forward higher requirements for grinding wheels in recent years with the rapid development of high-speed grinding and ultra fine grinding skills. Ceramic and resin bonded grinding wheels can no longer meet the production needs. Metal bonded grinding wheels have high bonding strength and good formability There are two main types of metal bonded diamond grinding wheels in production, namely sintering and electroplating, based on their distinct characteristics such as long service life. Especially for young operators, it is extremely unsafe to use excessive force to achieve fast grinding speed. Any flat body of a grinding wheel has a certain strength, which is likely to cause the grinding wheel to break or even fly out and injure people. This is also a behavior that should be stopped.
