THE BLOCKED REASON OF THE GINDING WHEEL ITSELF

In the process of using the grinding wheel, it often encounters the problem of blockage. There are two types of reasons affecting the blockage of the grinding wheel, one is the reason of the grinding wheel itself, and the other is the grinding conditions of the grinding wheel. Today we will talk about the main reasons for the blockage of the grinding wheel itself.

Abrasive type: different abrasive and workpiece material chemical affinity is different, grinding temperature is different, grinding force is different, in order to reduce the degree of blockage, different workpiece materials, should choose different types of abrasive.

Abrasive particle size: under the premise of the same size of the organization and grinding wheel, the finer the abrasive, the more grain number, the more uniform the arrangement, the more number of pores, the smaller the volume of single pores, under the same grinding parameters, the fine sand wheel is easy to plug.

3. Grinding wheel hardness

The grinding wheel with high hardness has serious scratching and extrusion on the workpiece before the dull abrasive particles fall off, and the abrasive chips are easy to fill the pores of the grinding wheel. The grinding process is accompanied by a large amount of friction heat, which provides the fuse for the adhesive plugging.

4. Grinding wheel structure

The grinding wheel structure reflects the proportion relationship between abrasive, binder and porosity. The denser the structure, the smaller the porosity ratio, the smaller the cutting edge spacing, and the more easily the grinding wheel is blocked.
