Selection of particle size and hardness of resin grinding wheel in resin grinding wheel factory
The resin grinding wheel factory believes that the particle size selection of the resin grinding wheel mainly depends on the surface roughness and grinding efficiency of the workpiece to be ground:
The particle size refers to the particle size of the abrasive, and its size is expressed by the particle size number. When grinding with a coarse-grained resin grinding wheel, the production efficiency is high, but the surface of the ground workpiece is rough; when grinding with a fine-grained resin grinding wheel, the surface roughness of the ground workpiece is better, but the productivity is low.
On the premise of meeting the roughness requirements, the resin grinding wheel factory should try to use the coarse-grained resin grinding wheel to ensure high grinding efficiency. Generally, a coarse-grained resin grinding wheel is used for rough grinding, and a fine-grained resin grinding wheel is used for fine grinding. When the contact area between the resin grinding wheel and the workpiece is large, the resin grinding wheel with a coarser particle size should be selected.
The hardness selection of resin grinding wheel mainly depends on the workpiece material to be ground, grinding efficiency and surface quality:
The hardness of the resin grinding wheel factory refers to the difficulty of the resin grinding wheel falling off the abrasive grains under the action of external force. In order to meet the grinding requirements of different workpiece materials, the resin grinding wheel is divided into different hardness levels when manufacturing.
The resin grinding wheel factory recommends that the selection of the hardness of the resin grinding wheel should be appropriate, and it should also be comprehensively considered according to the size of the contact area between the resin grinding wheel and the workpiece, the shape of the workpiece, the grinding method, the cooling method, and the type of binder of the resin grinding wheel.
