The reason for the sudden brushing marks on the work piece surface when machining the work piece by the cylindrical grinder

Dec 28, 2019

1. Mainly due to the coarse-grained grinding wheel abrasive particles fall off, sandwiched between the grinding wheel and the work piece formed 1, the marks left over from rough grinding are not worn away during fine grinding.

2. There are wear particles in the coolant.

3. The toughness of the material is too large.

4. The abrasive particles of the coarse-grained grinding wheel fall off when it is just trimmed.

5. The grinding wheel is too soft.

6. The grinding wheel is not trimmed, and there are protruding abrasive particles, which are broken or fall off during grinding.


When the work piece is machined by a cylindrical grinder, there are fine brushing marks on the work piece surface.

The main reason is that the fine-grained grinding wheel is broken or shedding between the grinding wheel and the work piece.

1. The grinding wheel is too soft.

2. The abrasive toughness of the grinding wheel and the material toughness of the work piece do not match properly.

3, the coolant is not clean, which causes the crushed particles or detached fine abrasive particles in the coolant to be embedded and squeezed between the grinding wheel and the work piece.
