Diamond belts are too soft. This problem generally occurs on sand belts made of animal glue, especially in the rainy season. Animal glue tends to absorb moisture and become soft and sticky. Therefore, semi-resin or full resin bonding should be used in the rainy season or wet areas. The abrasive belt produced by the agent. For the sand belt of animal glue, it is not advisable to open the sand belt packaging too early to avoid excessive moisture absorption. If possible, the animal glue can be dried or dried after being exposed to moisture, but the temperature should not be too high to avoid blistering or coking of the glue layer.Diamond abrasive belt

Abrasives are easy to blunt, but do not fall off. When grinding with abrasive belts, if the contact wheel is too soft, the abrasive on the sanding surface will not fall off but not sharp. If this happens, you should increase the grinding pressure or replace a harder contact wheel or a wider gear contact wheel or a small diameter contact wheel, or reduce the linear speed of the abrasive belt, etc., it can be solved The condition where the sand surface is not sharp.

It is easy to sand out, and the base is exposed. This is mainly because the abrasive grains are not firmly bonded, and the abrasive belt should be replaced. Or choose a softer contact wheel or a larger diameter contact wheel to increase the radius of curvature of the belt and reduce the grinding pressure, or choose a contact wheel with a narrower gear to increase the linear speed of the belt.

Abrasive layer clogging is mainly due to the wrong way of abrasive belt selection. If processing paint, you should use special coated abrasive belts. For example, when processing soft metal materials such as aluminum alloy, stainless steel, copper, etc., you should choose anti-lubricant, anti-coolant and water resistance. Abrasive belts are resistant to water and moisture. When grinding wood and its products, it is advisable to use black silicon carbide or brown corundum abrasives.
