Precautions for installing diamond grinding wheels

The use of grinding wheels has certain risks. Diamond Grinding Wheel The hardness of the diamond abrasive determines the main characteristics of the diamond grinding wheel, which can efficiently grind hard alloys, glass, ceramics and other difficult-to-machine materials, and the grinding tools have the longest service life. Grinder is one of the most commonly used machinery and equipment in machinery factories. Whether its installation is reasonable and whether it meets the safety requirements; whether its use method is correct and whether it meets the safety operation regulations. These problems are directly related to the personal safety of every employee, so we must pay enough attention in actual use.

When installing, first check the safety quality of the grinding wheel, tap the side of the grinding wheel with a velvet hammer (or a pen), and the sound is crisp and no problem. The diamond grinding wheel uses diamond abrasive as raw material, and uses metal powder, resin powder, ceramics and electroplated metal as binders respectively. The circular bonded abrasive tool with a through hole in the center is called diamond grinding wheel (alloy grinding wheel). Diamond Grinding Wheel The hardness of the diamond abrasive determines the main characteristics of the diamond grinding wheel, which can efficiently grind hard alloys, glass, ceramics and other difficult-to-machine materials, and the grinding tools have the longest service life.

Positioning problem: where to install the grinder is the first question to be considered during the installation process. Only when a reasonable and suitable position is selected, we can carry out other work. Grinders are not allowed to be installed in places that face nearby equipment and operators or where people often pass by. Generally, larger workshops should set up a dedicated grinder room. If it is indeed impossible to set up a special grinding machine room due to the limitation of the terrain of the workshop, a protective baffle with a height of not less than 1.8m should be installed on the front of the grinding machine, and the baffle should be firm and effective.

Balance problem: The unbalance of the grinding wheel is mainly caused by the inaccurate manufacture and installation of the grinding wheel, which makes the center of gravity of the grinding wheel and the rotary axis not coincident. The harm caused by unbalance is mainly manifested in two aspects. On the one hand, when the grinding wheel rotates at a high speed, vibration is caused, which is easy to cause polygonal vibration marks on the surface of the workpiece; on the other hand, the unbalance accelerates the vibration of the spindle and the wear of the bearing, which seriously It will cause the rupture of the grinding wheel and even cause an accident. Therefore, it is required that the sand office building with a straightness greater than or equal to 200mm should be statically balanced after the chuck is installed. After the grinding wheel is reshaped or unbalanced during work, the static balance should be repeated.
