Vitrified Bond Roll Grinding Wheel

Vitrified Bond Roll Grinding Wheel is mainly used on the roll grinder. Roll grinder is an indispensable production equipment in modern industry, such as metallurgical industry, paper industry and other industries. The precision and surface quality of rolls, in addition to the working precision of roll grinder, it also needs to rely on the choice of vitrified bond roll grinding wheel.

How to choose a right vitrified bond roll grinding wheel?

1, Selection of abrasives:

The abrasive of vitrified bond roll grinding wheel is mainly divided into corundum series and carbide series, and the choice of abrasives is based on the material of roller. Generally, corundum grinding wheel is selected for hardened or non-hardened steel rollers, then silicon carbide grinding wheel is selected for chilled cast iron rolls, rubber rolls, copper rolls and granite rolls.

2, Selection of grain size:

Generally speaking, coarse grained (24~60) grinding wheel is selected for coarse grinding; fine grained (60~100) grinding wheel is selected for fine grinding; the grinding wheel with particle size of 150 can be used in precision grinding; micro powder (W63~W14) grinding wheel is generally used in ultra-fine grinding or mirror surface grinding.

3, Selection of hardness:

The harder the surface of roller is, the softer the grinding wheel should be selected.

(1) If the wear speed of grinding wheel is too high, it means that the hardness of grinding wheel is too low. The following improvement measures can be taken:

A. Improving the linear speed of the grinding wheel.

B. Improving the longitudinal feed speed of the support plates, that is, increase the longitudinal feed rate of each support plate to 2/3~3/4 of the width of the grinding wheel.

C. Slow down the roller.

If no obvious grinding effect has been obtained after taking the above measures, it means that the grinding wheel is too soft and is not suitable, so a harder grinding wheel should be selected.

(2) If the grinding wheel is blocked when grinding the roller, the passivated sand particles are not easy to fall off, the wear debris are easy to stick to the grinding wheels, and grinding burning appears on the surface of the grinding wheel, then it means that the grinding wheel is too hard, and the following measures can be taken to improve it:

A. Reduce the grinding wheel's linear speed.

B. Increase roller speed.

If no obvious grinding effect has been obtained after taking the above measures, it means that the grinding wheel is too hard, so a softer grinding wheel should be selected.
