The structure of grinding wheel is composed of a large number of unevenly distributed particles. Inherent imbalance can not be avoided, which will inevitably cause certain eccentric vibration. However, eccentricity of grinding wheel installation, uneven thickness of grinding wheel, unbalance of spindle and adsorption of coolant by grinding wheel will increase vibration even more. These vibrations not only affect the processing quality of the grinder, but also reduce the life of the grinder spindle and grinding wheel, increase the number of grinding wheel modifications and the consumption of the dressing diamonds.
It is well known that grinding wheel is a necessary tool for grinding machine. In order to grind a precise size and smooth surface, vibration during grinding must be prevented. A series of disc rotor dynamic balancing problems such as grinding wheel and grinding wheel can be solved by the dynamic balancing machine developed and manufactured by Huakezhi Creative Balancer.
The application of on-line dynamic balance correction of grinding wheel is an indispensable part of modern grinding process. When the internal and external environment vibration of grinding machine is good, the residual vibration of grinding wheel after on-line dynamic balance correction will be optimized by an order of magnitude compared with the traditional manual static balance effect. The comparison is made on the basis of Peak to Peak measurement. When the static balance is 3. μ At m the dynamic balance can reach 0.3 μ M. Combining the advantages of on-line dynamic balance correction, the grinding industry can obtain the following economic benefits.
1. It can greatly improve the true roundness, cylindricity and surface roughness of the grinded workpiece.
2. It can prolong the life of the work piece being ground, reduce the phenomenon of grinding burns and cracks, and control the low-frequency working noise.
3. Improve grinding precision, stability and batch consistency (CP value);
4. It can extend the service life of traditional grinding wheel and diamond grinding wheel dressing device.
5. It can ensure the service life of grinder spindle and bearing, extend the service interval of grinder and reduce the maintenance cost of grinder.
Unbalanced grinding wheel refers to the fact that the center of gravity of the grinding wheel does not coincide with the centre of rotation, i.e. the center of gravity of the grinding wheel deviates from the centre of rotation. To balance the grinding wheel, several balancing blocks are usually installed in the annular groove of the flange disc of the grinding wheel, and the position of the balancing blocks is adjusted so that the center of gravity and the centre of rotation of the grinding wheel coincide The suitable equipment for checking and correcting the dynamic balance of grinding wheel is ring belt balancer and vertical balancer.
Grinding machine is indispensable for precision machining. In order to meet the increasingly precise requirement of working accuracy and the continuous pursuit of high efficiency and low cost, the global grinding machine manufacturing industry has been working tirelessly to improve the geometric accuracy, rigidity and performance stability of machine tools.
