Glass fiber mesh abrasive cloth belt  by weaving, the use of a coating material for surface processing a lattice braid. Item Unit Technical performance indicators / (standard mesh) mesh center distance MM 4 ~ 6 mass per unit area G/M2 ≥ 160% ≤ 5 Alkali fracture strain fracture strength retention (warp and weft)% ≥ 50 Alkali breaking strength retention value N/50MM ≥ 750 Alkali-wave fiber network across the fabric (gel content)% ≥ 8 alkali-type wave webs every cloth (gel content)% ≥ 20 emery cloth (paper) shabu (zhi) emery cloth (paper) abrasive cloth or paper with an adhesive to adhere the abrasive cloth or paper substrate on the page like coated abrasives. Emery cloth and sandpaper is coated abrasives in history, the largest amount of a kind widely used in various hand-sanding operations. Emery cloth (paper) standard specifications for the 230 × 280 mm, dry grinding, water, gold equal to the main species. ① dry sanding cloth: also known as sand paper to fabric as matrix to gelatin as a binder for abrasive corundum is made mostly for rust and polishing metal materials, but also for sanding wood. ② dry sanding paper: also known as wood sandpaper, paper as base to gelatin as a binder for glass sand or emery and other natural abrasives made of, used for sanding wood. ③ waterproof sandpaper: the paper as the substrate, to varnish as a binder to corundum or silicon carbide abrasive made of green, used for metal polishing and paint putty sanding. ④ emery paper: paper as the matrix, as a binder resin, made with silicon carbide for abrasive, used for metallographic grinding and polishing. Variety of emery cloth (paper) its use can be made of different size requirements of different products to the abrasive grit that their thickness.

A large area of ​​the abrasive cloth belt  . Maximum wheel width is only 1000mm, 2500mm above the belt can be done . Now known to the widest belt wide belt grinding machine used 4900mm. Actual use common processing belt grinding width of 50 ~ 2000mm, Thickness 0.4 ~ 150mm. Their productivity up 1000m2 / h. This wide belt grinding can be widely used in steel, stainless steel , silicon steel , aluminum, copper, particleboard, plywood , MDF , leather, insulation boards, ceramic plates , and aerospace equipment, ships and nuclear physics research device use a variety of high-precision low- roughness surface processing such large plates . Such as intermittent engine gearbox section plane can also be used for precision machining forming a wide belt grinding , and to ensure than conventional milling, planing surface machining a better seal.
Metal strip or wire continuous polishing process . Because of the wide belt grinding of development, so that thin strip across the width have the same grinding conditions , and will not localized excessive force , resulting in stress and deformation , so the cold rolled steel, copper , aluminum and other alloy strip and other surfaces are suitable for continuous use abrasive polishing . The processing width of 600 ~ 2100mm, Thickness 0.1 ~ 2.2mm, the surface roughness Ra3.2 ~ 0.1mm, the strip running speed is 3 ~ 80m/min. Planetary belt grinding of stainless steel or other materials, polishing roll the wire provides a very efficient and economical processing methods. Known polishing wire diameter 0.8 ~ 20mm. Continuous speed 6 ~ 150m/min.
Large aspect ratio of the workpiece , the cylindrical polishing . Modern industry in a variety of large, large aspect ratio of the shaft and the cylindrical workpiece Tube inner peripheral surface of the workpiece processing and utilization of belt grinding is very convenient. Generally available in large standard equipment to add a belt grinding device can be realized . Large quantities may be using a dedicated belt grinder. Such as a large generator rotor , rollers , paper and other parts of the outer cylinder and cylinder , oil pipelines , pressure vessels and other parts of the inner circle surface processing.
Complex shaped workpieces polishing . Workpiece surface profile grinding , difficult. However, the use of a flexible belt can easily process a variety of complex surfaces , the inner radius of curvature of only 3mm fillet , belt can be polished . Plates such as aircraft engines , turbine blades, vanes navigation , condenser lamp bowls , mirrors, cutlery , handle , plumbing appliances , etc. are available for efficient high-quality abrasive polishing process .
