Stone polishing machine is a kind of processing machine, it is hard to avoid some wear and tear when it is used for a long time. Methods for removing sand marks from stone polishing machine are as follows:
a. When adjusting the press mill, do not press with force, need to adjust gently, so as to avoid the sand grains in the 180 belt are stressed, easy to drop grains and sand holes.
b. Before using the stone polishing machine, use a feeler gauge to adjust the cutting amount of each grinding.
c. Open the stone polishing machine to check whether there is damage or sand hole on the workpiece. Replace the belt with a new one. The service time of one sand belt is 2 hours and it should be replaced in time.
d. If there are sand marks after adjusting the stone polishing machine or replacing the abrasive belt, it should be adjusted and polished repeatedly.
e. If it is necessary to use coarse sand belt or sandblasting belt, stop recovering dust for about 4 hours.
f. Ensure that the stone polishing machine is often used, there is no ash blocking at the bottom, and the entrance door can not be adjusted at will, so as to reduce the sand cleaning effect.
Deburring, finishing and polishing of stone polishing machine are different processes. Deburring is to remove and finish the residue after forging, which is whether the surface of the object is smooth or not. Stone polishing machine is equivalent to finishing work, that is, polishing and brightening objects to improve the "face value". Powder metallurgy is an industrial technology that uses metal powder or metal powder as raw material to make metal materials, composite materials and typical products of various materials through molding and sintering. Powder metallurgy materials have wear resistance, heat resistance and other properties, and will be gradually replaced by some traditional metal materials as advanced composite materials for electronic industry and other fields. Stone polishing machine is often used for powder metallurgy materials, through mirror polishing, to achieve the effect of bright appearance.
