Three-step mirror polishing is polishing power tools in order with the use of composite louvered discs, synthetic grinding discs, wool strips polishing discs and other three kinds of polishing materials for mirror polishing, grinding process for the composite louvered mechanical mirror polishing is in the metal material after the grinding process (coarse grinding, fine grinding) and polishing process (WENDT three-step polishing) to achieve a smooth, bright like mirror-like surface.
I. Polishing process
The purpose of grinding is to obtain a flat and smooth grinding surface. At this time, there are still very fine and uniform grinding marks on the grinding surface. Grinding is divided into two kinds of coarse grinding and fine grinding.
1. rough grinding rough grinding is the rough surface and irregular shape correction molding.
2. fine grinding after rough grinding the metal surface still has a very deep abrasion marks, need to be eliminated in the fine grinding, in preparation for polishing.
Second, the surface polishing process
Polishing process is to obtain a bright mirror-like surface processing. Most of the use of polishing wheels to repeatedly polish the surface of the part after a very small unevenness, generalized to the plated surface modification.
Polishing is the last process on the plated surface or on the surface of the part, the purpose of which is to eliminate the fine abrasive marks that remain on the surface after the buffing process. Ideal polished surface should be flat, bright, no marks, no relief, no pits, no metal disturbance layer like mirror state of the surface. After grinding and polishing after the grinding surface changes.
Three-step mirror polishing is polishing power tools in order with the use of composite louvered discs, synthetic grinding discs, wool strip polishing discs and other three kinds of polishing materials for mirror polishing, grinding process for the composite louvered discs, synthetic grinding discs, surface polishing process for the wool strip polishing discs.
Step 1: Composite louvered disk
The structure of the composite louvered disc combines surface polishing materials and coated abrasives to remove rough surfaces and irregular shapes, and to realize rough grinding and preliminary fine grinding.
Step 2: Synthetic Discs
Highly concentrated abrasives are distributed on a strong non-woven base material to remove stainless steel surface calendars or burrs, enabling fine grinding in preparation for polishing.
Step 3: Wool strip polishing disk
Wool strip discs are flexible and easily cooled by accelerated air flow and are suitable for use with polishing waxes or pastes to achieve a mirror-like finish as the final step in the metal surface finishing process.
