The Importance of Dynamic Balance Correction for Grinding Wheel
The structure of a grinding wheel is composed of a large number of unevenly distributed particles, and inherent imbalance cannot be avoided, which will inevitably cause a certain degree of eccentric vibration. The eccentricity of the grinding wheel installation, uneven thickness of the grinding wheel, imbalance of the spindle, and adsorption of the cooling liquid by the grinding wheel will further increase the vibration. These vibrations not only affect the machining quality of the grinder, but also reduce the spindle life and wheel life of the grinder, increase the number of wheel corrections, and consume diamond dressing.
As is well known, grinding wheels are essential tools for grinding machines. In order to achieve accurate dimensions and smooth surfaces, it is necessary to prevent vibration during the grinding process. The grinding wheel dynamic balancing machine developed and produced by Huake Zhichuang can solve a series of disc-shaped rotor dynamic balancing problems such as grinding wheels and grinding wheels.
The application of online dynamic balance correction for grinding wheels is an indispensable and important project in modern grinding technology. When the internal and external environment of the grinding machine vibrates well, the residual vibration of the grinding wheel after online dynamic balance correction will be further optimized by an order of magnitude compared to the traditional manual static balance effect. When the static balance is 3 μ m, the dynamic balance can reach 0.3 μ m. Taking into account the advantages of online dynamic balance correction, grinding industry workers can obtain the following economic benefits.
1. Can significantly improve the roundness, cylindricity, and surface roughness of the ground workpiece;
2. Can extend the service life of the workpiece being ground, reduce the phenomenon of grinding burns and cracks, and control its low-frequency working noise;
3. Improve the precision, stability, and batch consistency (CP value) of grinding processing;
4. Can extend the lifespan of traditional grinding wheels and diamond grinding wheel dressing devices;
5. It can ensure the service life of the grinder spindle and bearings, extend the maintenance interval of the grinder, and reduce the maintenance cost of the grinder.
Wheel unbalance refers to the misalignment between the center of gravity of the grinding wheel and the center of rotation, which is caused by the deviation of the center of gravity of the grinding wheel from the center of rotation. To balance the grinding wheel, multiple balancing blocks are generally installed in the annular groove of the grinding wheel flange, and the position of the balancing blocks is adjusted to make the center of gravity of the grinding wheel coincide with the center of rotation, thus achieving wheel balance; The equipment suitable for detecting and correcting the dynamic balance of grinding wheels includes belt balancing machines and vertical balancing machines.
Grinding machine is an essential working machine for precision machining. In order to meet the increasingly precise work accuracy requirements and the continuous pursuit of high efficiency and low cost goals, the global grinding machine manufacturing industry is tirelessly committed to improving the geometric accuracy, rigidity, and performance stability of machine tools.
