Precautions for the use of white corundum grinding wheel?
The grinding wheel is one of the widely used grinding tools. It is a bonded abrasive tool that bonds ordinary abrasives into a certain shape (mostly round with a through hole in the middle) and has a certain strength. White corundum grinding wheels and brown corundum grinding wheels are commonly used, which are dangerous in use. For your safety, today we mainly introduce the precautions for the use of white corundum grinding wheels. The precautions in use are listed below: The grinder is one of the most commonly used machinery and equipment in the machinery factory. Whether its installation is reasonable and whether it meets the safety requirements; whether it is used correctly 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 to them in actual use.
It is forbidden to install white corundum grinders in places facing the white corundum of nearby equipment and operators, or where people often pass by. Generally, a special grinder room should be set up in larger workshops. If it is really impossible to set up a dedicated grinder room due to the topography of the plant, a protective baffle with a height of not less than 1.8m should be installed on the front of the grinder, and the baffle must 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, so that the center of gravity of the grinding wheel does not coincide with the rotary axis. The harm caused by imbalance is mainly manifested in two aspects. On the one hand, when the grinding wheel rotates at a high speed, it will cause vibration, which is easy to cause polygonal vibration marks on the surface of the workpiece. The unbalanced acceleration of white corundum powder will accelerate the vibration of the spindle and the wear of the bearing, which is serious. Sometimes it will cause the grinding wheel to break and even cause an accident. Generally, a special grinding wheel room should be set up for the grinder.
It is strictly forbidden to stack flammable and explosive materials in the grinder room or near the grinder to avoid fire or explosion accidents, and other parts or objects should not be placed near the grinder.
Management issues: The grinder should have a dedicated person in charge. Anyone who does not want to grind objects on the grinder must obtain the permission of the full-time person in charge, and strictly abide by the safety operating procedures. It is strictly forbidden to use the grinder without the consent of the person in charge. . In addition, the replacement of the white corundum grinding wheel should also be handled by a dedicated person, and it is forbidden to replace or install the grinding wheel without permission.
Turn off the car: After the operator stops working, the car should be turned off immediately. It is forbidden for the grinder to run idly when no one is used or managed. Gradually, keep the medium and short wave turbine clean after use.
In daily use, many operators are always accustomed to operating directly on the grinding wheel. The reason is that the force can be used in this direction. In fact, this behavior is a behavior that should be particularly prohibited in the operation of the grinder. According to the operating regulations, when using the white corundum grinder to grind the workpiece, the operator should stand on the side of the grinding wheel and not operate on the front of the grinding wheel, so as to avoid the grinding wheel flying out or the grinding wheel breaking out and hurting people when the grinding wheel fails.
Forced operation problem: When using the grinder, some operators, especially young operators, use excessive force to achieve a fast grinding speed. This is an extremely unsafe operation behavior.
