In the process of metal polishing, sand paper manufacturers must possess high quality metal polishing materials, such as oil stone, abrasive paper, lapping compound and other auxiliary polishing materials if we want to get high quality polishing effect. At the same time, it also depends on the surface condition of polishing tools. So, what needs to pay attention for metal polishing material sand paper when polishing? Let’s continue to read.

Some notes for sand paper polishing materials:

A. when we need switch to a different type of sand paper, the polishing direction should transform to 45 °~90 °. So the stripe of shadow left by the previous sand paper polishing can be distinguished. Before changing different types of sandpaper, we must take alcohol or other cleaning fluid to carefully wipe the polishing surface with 100% pure cotton, because a tiny grains of sand on the surface will also destroy the whole polishing work. And when we change from sand paper polishing to diamond lapping compound polishing, the cleaning process is equally important. What’s more, all particles and kerosene must be completely clean before polishing.

B. In order to avoid the scratch and burn the surface of workpieces, we must be especially careful in the process of polishing with #1200 and #1500 sand paper polishing materials. Therefore, it is necessary to load a light load and take two-step polishing method for polishing on the surface. Different sand paper should be along two different directions for twice polishing, and the two directions should keep rotated about 45 °~90 ° every time.

C. We need to use a soft stick or bamboo stick when using sand paper for polishing. When polishing the round surface or spherical surface, the use of soft stick can better meet with round the radian of plane and spherical surface. And if it is a hard wood like cherry wood, it is more applicable to the level surface polishing. Dressing the end of the wood to keep consistent with the surface shape of steel products, you can avoid the acute angle of wood or bamboo exposed to the surface of steel products and cause deep scratches.
