Grinding-----Surface finishing, Surface treatment on prototype. (1)

- Jun 06, 2018 -

During the whole process of hand-slab processing, most of the hand-made plates undergo surface treatment through appropriate processing methods (CNC or 3D printing). The purpose of the surface treatment is to satisfy corrosion resistance, abrasion resistance, decorativeness or other SP requirements. The product features a full range of functions and there are dozens of processing techniques for the prototyping processing. As a large-scale hand-saw factory, RMT PRODUCTS CO., LTD can provide most of the surface processing requirements for manual processing, and has a standardized production process. Next, it introduces the surface treatment technologies commonly used in manual processing.


1. Grinding Grinding is one of the most commonly used surface treatment technologies. Generally, rough objects (such as high-hardness sandpaper, etc.) are used to change the physical properties of the material surface by friction and remove defects on the workpiece surface, processing line, and ADH surface. In order to improve the flatness of the workpiece and reduce the roughness, the workpiece surface is smooth and smooth.

2. Polishing Polishing is the use of flexible polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece on the basis of grinding, polishing can not improve the dimensional accuracy or geometric accuracy of the workpiece, but in order to obtain a smooth surface or mirror. Gloss, sometimes eliminating gloss (extinction). The surface roughness of the workpiece after polishing is generally Ra0.63-0.01 micron.
