Be careful during the operation of the diamond grinding wheel. Usually, people often encounter the following major problems during the operation of the diamond grinding wheel. Therefore, I will summarize the following for you, hoping to help more people understand how to operate the diamond. Grinding wheels and what to pay attention to during the operation of the diamond grinding wheel.

1. Side grinding:
In the daily use of the long life grinding wheel, it is also necessary to classify the grinding wheel. However, in the daily use process, many operators do not use the type of grinding wheel to randomly grind the side of the grinding wheel. In order to give full play to the role of the diamond, it is necessary to try to Increase the holding force of the bonding agent on the diamond and increase the bonding strength of the grinding wheel.

The single-layer high-temperature brazing super-abrasive grinding wheel can overcome the shortcomings of the electroplated grinding wheel, and can realize the chemical metallurgical combination between the diamond, the bonding agent and the metal matrix, and has a high bonding strength, and only needs to maintain the thickness of the bonding layer in the grinding. 20% to 30% of the height of the grain can firmly hold the abrasive grains in high-load high-speed and high-efficiency grinding, so that the abrasive height of the brazing wheel can reach 70% to 80%, thus increasing the chip space. The grinding wheel is not easy to block, and the use of abrasive is more sufficient.

This is a violation of the rules of operation for serious violations of safe operating procedures. According to the regulations, the long life grinding wheel with the circumferential surface as the working surface should not be ground. The radial strength of the grinding wheel is large, and the axial strength is very small. When the operator is too strong, the grinding wheel will be broken and even hurt, in practice. This behavior should be prohibited during use.

2. Positive operation:
In daily use, many operators are always used to operate on the grinding wheel. Sintered metal bond grinding wheels are mostly made of bronze and other metals as a bonding agent. They are manufactured by high-temperature sintering method, which has high bonding strength, good formability, and high-temperature resistance. It has good thermal conductivity and wear resistance, long service life and can withstand large loads. The reason is that it can be used in this direction. In fact, this behavior is a special prohibition in the operation of the grinding wheel. According to the operating procedure, when grinding the workpiece with China long life grinding wheel, the operator should stand on the side of the diamond grinding wheel and not operate on the front side of the grinding wheel, so as to avoid the grinding wheel flying out or the grinding wheel breaking out and hurting when the grinding wheel fails.

3. Forced operation:
In the use of China long life grinding wheels, some operators, in recent years, with the rapid development of high-speed grinding and ultra-precision grinding technology, the long life grinding wheel is put forward higher requirements, the grinding wheel of ceramic and resin bond cannot meet the production Needed, the metal bond grinding wheel is obtained in the production of metal bond diamond grinding wheel due to its high bonding strength, good formability, long service life and other significant characteristics. There are two types of sintering and electroplating. Especially for young operators, the speed of grinding is too fast and the force is too strong. This is a very unsafe operation. The flatness of any grinding wheel has a certain strength, which is likely to cause the grinding wheel to break, or even fly out and hurt people. It is also a prohibited behavior.
