1.Working principle of abrasive brush

The brush wire used by the abrasive brush is evenly dispersed with silicon carbide grit with sharp cutting edges. No matter how the shape of the brush wire changes during use, it can ensure that the edge of the grit rests tightly on the surface of the workpiece; When the surface moves, the brush wire will arbitrarily bend with the uneven surface of the workpiece. The sharp edges of the sand particles will be used to polish the workpiece surface in all directions. With the increase of the number of brushes, the volume of the sand particles will gradually decrease, and the grinding marks will gradually decrease. , Until the brushed workpiece keeps the surface uneven, while showing the satin mercerizing effect.

2.Use abrasive brushes correctly

A. Cooling water should be added at high speed during grinding and polishing to prevent the brush wire from deforming due to the high temperature caused by the high-speed friction of the brush wire.

B. With the working order of the number of grinding brushes from coarse to fine, the working pressure of the grinding head should also be from large to small.

C. Jumping numbers should be reasonable. Too much reduction of intermediate links will affect the grinding effect, but may increase production costs.

D. Use coarse-grained abrasive brushes as much as possible to reduce the wear of the abrasive brush wires and prolong the service life of the abrasive brushes.

3.Selection principle of grinding brush

Generally speaking, the 36 # and 46 # abrasive brushes are used to remove surface loose objects and sharp particles on the brick surface (that is, deburring); 60 #, (70 #) 80 # are used for rough grinding; 120 #, 180 #, 240 # Can be rough-polished; 320 #, 500 # are fine polished to make the brick surface achieve silk satin gloss effect. If it is the first time to use the abrasive brush, it should be tested for various models and selected according to the type and the grinding effect to be achieved.

4.Selection example of grinding brush

A. After the bricks come out of the kiln, they are processed directly with abrasive brushes.

Effect: matte surface with uneven surface (leather feel), good antifouling performance, gloss can be controlled at 6 ~ 15 degrees

Brush arrangement:

B. After rough polishing by the polishing machine, the brick is processed by the abrasive brush.

Effect: The surface is flat and has a delicate matte effect. The antifouling performance is determined by the texture of the brick surface, and the gloss can be controlled at 8-20 degrees.

Brush arrangement:

Remarks: The above is the usual method, but according to the size of the brick, the rough surface of the brick before processing, the speed of the polishing machine, the number of the same number of grinding brushes is selected; The maximum number of meshes can reach 1000 #.
