It is mainly suitable for small and medium-sized fine machining and irregular parts processing. Widely used in all kinds of welding, polishing, grinding, and workpiece deburring, plasma cutting, etc. . Widely used in food processing, building materials, metallurgy, industrial, chemical, dust removal, material recovery and air filtration in electric power, mechanical manufacturing, foundry and other industries. The dust-removing and sanding worktable is one of the advanced pulse-jet filter-type dust-removing equipment in the domestic production technology, with simple operation, low noise, long service life and good environmental protection, very suitable for wood products, iron products, abrasives factory, building materials factory and chemical products and other parts of the grinding and manufacturing. Its operating principle is mainly to rely on the centrifugal fan suction effect, so that the table after the generation of negative pressure capture dust.
