The choice of silicon carbide sandpaper and material have no relationship,, regardless of the material and hard to go through rough grinding, fine grinding, polishing, etching process. Generally choose No. 100 200 400 No. No. 600 800 No. 1000 No. can, if the lack of one or two, little relationship, spring steel is hard should better grinding, because the soft material is easier to form the scratches.
Silicon carbide sandpaper is divided into dry sandpaper and water sandpaper, we generally choose water sandpaper, inverse can choose according to their own situation.
Sandpaper the brand is very important, choose when looking at the thickness of is divided into dry sandpaper and water sandpaper, we generally choose water sandpaper, inverse can choose according to their own situation.
The brand of silicon carbide sandpaper is very important, choose when looking at the thickness of sandpaper, must not be too thin.There is a strong degree of sand, the distribution is uniform.
Water silicon carbide sandpaper is washed in water for polishing, is generally used in the machine.The abrasive sandpaper is composed of particles, natural corundum alumina and iron oxide and sandpaper, gray green.General steel materials for fine grinding can be used for 280, 320, 400, 500, 600 of the five grain sandpaper. Grinding depends on whether you're buffed the scratch is not fine, the fine polishing required less time sample in the subsequent etching process more able to show the actual organization.
Specifications of silicon carbide sandpaper: label M40 (or W40 said maximum size is 40 m, M28 (W28) said the abrasive particle size for a maximum of 28 m. General steel materials with 280, M40, M28, M20 four grain sandpaper fine grinding can be; or code available for 0, 01, 02, 03 four sandpaper polishing. Generally from coarse to fine polished four sandpaper, before pushing, lifting, back, then push forward three basic movements. The specimen is then gently pressure in the sand paper to. The last line of sandpaper size should be between 10 ~ 20 m, water sand paper burnish, water sandpaper abrasive grains are silicon carbide, plastic or non water soluble binder to different mechanical polishing can use water sandpaper to polish and wax disc polishing.
