Resin grinding wheel is a grinding wheel made of resin. Such as phenolic, epoxy, polyurethane, polyvinyl alcohol, etc. The resin abrasive wheel has high strength, and can add reinforcing fiber mesh and steel bars to the abrasive wheel. Such as cutting discs, grinding discs. Most of our resin wheels are not waterproof and cannot be ground with abrasive fluids. Of course, there are also some resin grinding wheels that need to be ground with grinding fluid. Such as epoxy and resin grinding wheels, the grinding smoothness is good, and the workpiece is not easy to burn. Resin grinding wheels are used in cutting discs, double face, heavy duty grinding wheels, polishing wheels, etc. The strength of resin bond abrasive wheel is lower than that of metal bond and vitrified bond.
The resin abrasive wheel has high hardness, high strength, strong grinding ability, and is widely used. When we use resin grinding wheels, the phenomenon of abrasive wheel imbalance often occurs. How did this phenomenon come about, and what are the consequences?
The resin grinding wheel has a certain elasticity, which is beneficial to improve the roughness of the workpiece surface. Mainly used for fine grinding, semi-fine grinding, knife grinding, polishing and other processes. The reason why the resin abrasive wheel is unbalanced during use is that the center of gravity of the grinding wheel does not coincide with the axis of rotation. The reason for this is a manufacturing and installation defect of the abrasive wheel. For example, the density of the abrasive wheel is not uniform. Geometry or concentricity error of inner and outer holes, non-parallel end faces, eccentricity of abrasive wheel installation, etc. When the unbalanced abrasive wheel rotates at high speed, it will generate centrifugal force that forces the grinding wheel to deviate from the axis, causing the abrasive wheel to vibrate. The consequences not only affect the grinding quality, but also accelerate the wear of the abrasive wheel spindle bearings.
Resin grinding wheels are mainly used for grinding high and hard alloys, non-metallic materials, cutting hard and brittle carbides, non-metallic minerals, etc. Such as cemented carbide, ceramics, agate, optical glass, semiconductor materials and wear-resistant cast iron, stone, etc. Resin abrasive wheel has a good polishing effect, welcome to inquire.
