With the development of industry, the increasing precision of cutting tools has made CNC tool grinders one of the most commonly used machine equipment in tool factories. Whether its installation is reasonable and meets safety requirements; Is its usage method correct and in compliance with safety operating procedures. These issues are directly related to the personal safety of every employee, so they must be given sufficient attention in practical use
The location of the positioning problem grinder equipment installation is the first issue we need to consider during the installation process. Only by selecting a reasonable and suitable location can we proceed with other work. Grinding equipment is prohibited from being installed directly in front of nearby equipment and operators, or in places where people often pass by,
The imbalance of the grinding wheel is mainly caused by inaccurate manufacturing and installation of the grinding wheel, resulting in the center of gravity of the grinding wheel not coinciding with the axis of rotation. The hazards caused by imbalance mainly manifest in two aspects. On the one hand, when the grinding wheel rotates at high speed, it causes vibration, which can easily lead to the formation of polygonal vibration marks on the surface of the workpiece; On the other hand, imbalance accelerates the vibration of the spindle and the wear of the bearings, which can cause serious damage to the grinding wheel and even lead to accidents. Therefore, for sand office buildings with a diameter greater than or equal to 200mm, static balancing should be carried out first after installing the chuck. If the grinding wheel is found to be unbalanced after shaping or during work, static balancing should be repeated.
Matching problem mainly refers to the installation and matching problem between the chuck and the grinding wheel. According to the standard requirements, the diameter of the grinding wheel chuck shall not be less than one-third of the diameter of the installed sand office building, and it is stipulated that when the grinding wheel wears to a diameter 10mm larger than the chuck diameter, a new grinding wheel should be replaced. This creates a matching problem between the chuck and the grinding wheel, otherwise there may be a situation where the "big horse pulling the small car" causes waste of equipment and materials; The practice of 'small horses pulling large carts' does not meet safety requirements and can easily lead to personal accidents. Therefore, the reasonable matching of chuck and grinding wheel can save equipment and cut materials on the one hand; On the other hand, it also meets the requirements for safe operation. In addition, a soft pad with a diameter greater than 2mm and a thickness of 1mm~2mm should be installed between the grinding wheel and the chuck.
