How to choose grinding pressure when grinding workpiece with surface grinder?

Hyde Grinding shares with you how to choose grinding pressure when grinding workpieces with a surface grinder. And the influence of too much or too little pressure on grinding workpiece?

In the grinding process, the contact area between the workpiece and the grinding disc is from small to large. If the grinding pressure is properly adjusted, higher efficiency and higher surface finish can be obtained.

On the surface grinder, grinding

The grinding pressure should not be too high. If the hardness of the grinding disc is high and the grinding pressure is too high, the abrasive particles will be crushed quickly and the cutting ability will be reduced. Especially when the hardness of the grinding disc is low.

When the grinding pressure is too high, abrasive particles will be embedded in the surface of the grinding disc, which greatly increases the cutting ability. However, the workpiece and grinding disc will be deformed due to the intensification of grinding action, which directly affects grinding.

The quality of grinding workpiece and the life of grinding disc itself. On the contrary, the grinding pressure must be too small. If the pressure is too small, the cutting ability will decrease and the production efficiency will decrease. In a certain range, the grinding pressure

Force is directly proportional to efficiency.

Grinding pressure-generally 0-5 kg +0.65438 per square centimeter. Generally, the pressure during rough grinding by hand is about 0/~ 2 kg per square centimeter/kloc-0, and the pressure during fine grinding is about 0. 1 ~ 0.5 kg per square centimeter.

For the Hyde plane

For grinding, the grinding pressure can be reduced because of the large friction when the grinder is turned on, and it can be adjusted to a constant value during grinding. At the end of grinding, the grinding pressure can be adjusted in order to obtain high-precision effect.

The intensity can be reduced a little. Practice shows that the surface smoothness of the workpiece will decrease with the increase of pressure within the range of pressure used. When the grinding pressure is in the range of 0.4-2kg/cm2, it is very effective to improve the surface smoothness of the workpiece. Generally speaking, for thin plane workpieces, the maximum allowable pressure is 3kg/cm2.

Grinding pressure refers to the pressure per unit area of the workpiece. The total pressure is the sum of the weight of the workpiece and the soil grinding disc and the external pressure. For example, the grinding pressure of a single piece can be obtained by roughly grinding the workpiece on a 38 16 disc grinder, and the number of processed pieces is 80. In fact, Shenzhen Hyde found that the pressure is greater than the calculated pressure, which is mainly caused by the large difference in workpiece size and the small contact area with the grinding disc.

The above is the selection method of grinding pressure when the surface grinder processes the workpiece. I hope it will help your work.
