Marble specification plate production process points
Marble specifications plate thickness of 20mm, marble specifications plate production process can be divided into first after the mill and the first mill thick cut two. The first is to cut after the first grinding, mainly for the processing of small size of the product specifications, the production process is as follows: Cut the hair board - cut off - rough grinding - fine grinding - refining - polishing - repair - inspection - Packaging storage .
1 cut the hair board
The board cut from the marble block is called a board. Cutting the hair board equipment diamond sawing machine and diamond cutting machine or cutting machine. Use of diamond frame saws for large blocks, diamond cutters and large cutters for small blocks.
2 cut off
The use of bridge cutting machine for cutting board processing.
3 coarse grinding
The purpose of coarse grinding is mainly to solve the flatness and thickness of the plate, most of the grinding allowance to be removed in the rough grinding stage, coarse grinding the first choice of grindstone should be based on the surface roughness of the wool board to choose. If the surface roughness or large thickness deviation, optional diamond grinding wheel leveling. When the wool surface roughness is small, the thickness deviation is small, the general use of grinding directly grinding. Rough grinding operation is generally a drive before the application of flat-foot test board surface roughness b to determine the good side of the surface as a precision machining c surface before grinding, polished surface, and then to the bottom surface to find the thickness of d grinding When the water should be continuous e to avoid grinding stone collide with the side of the semi-f side edge inspection g Grinding board should be the serial number flat, block by block test, the quality of qualified to be transferred to the next procedure.
4 fine grinding
The main use of fine grinding No. 2, No. 3, No. 4 millstone, according to the order of grinding. Each use of a millstone must wear away the scratches left by the previous process. By fine grinding, you can remove rough coarse grinding plate surface and deep lines and new grinding lines.
Grinding the use of No. 5 and No. 6 grindstone, polished gloss up to 60 degrees can be transferred to the next step for polishing.
Indicators. Polishing can be polished in the rock is the inherent pattern of stone, color gloss to maximize the final result, to achieve the best results, especially gloss must meet or exceed the standard provisions of the arm mill, semi-automatic polishing machine, bridge Mill, such as the use of resin mill must choose the right resin.
7 repair, inspection, packaging and storage
After polishing to Spain beige marble plate repair, inspection, after passing the packaging storage.
The second standard plate processing technology is the first mill after cutting, the production process is as follows: Cutting board - coarse grinding - fine grinding - fine grinding - polishing - cutting - repair - testing - packaging storage. The second process can make effective use of sheet metal.
