Resin cutting sheets, also known as resin cutting sheets, are mainly resin abrasives made of chemical synthetic fiber fabrics, which have relatively high tensile, impact and flexural strength, and have high line speed when used. Resin 6 inch es cutting disc are often mounted on electric and pneumatic sanders for repairing various metal surfaces, cleaning welds, solder joints, descaling, grinding burrs, flashing edges, repairing surface defects, and workpiece grooving and Cut off the work. The use of resin cutting sheets is efficient and safe, and is suitable for chemical, shipbuilding, machinery, automotive, construction and other industrial sectors.
The manufacture of resin dicing sheets is a highly technical industrial product. The problems in the various processes of compounding, molding, hardening and processing will affect the quality of the products:
1. Mixing process: The key of mixing is uniformity. The molding material should reach: the distribution of each component is uniform and keep loose, but it is not suitable for obvious powder leakage. It must ensure uniform distribution and good molding performance.
2, molding process: At present, most of the domestic rotating material distribution mechanism, but due to the limitations of the rotating material distribution mechanism, the employees of some manufacturing enterprises have no way to operate, the distribution of mixed materials is uneven, row tolerance and static balance Very bad.
3, resin cutting sheet hardening process: This is the most critical production process, there are two factors that easily cause quality problems, one is the temperature difference between the curing oven or the firing kiln is too large; the second is improper way of loading the furnace. The temperature difference of the hardening furnace is too large, so that the hardening of the resin cutting sheet deviates from the set hardening specification, so that the curing quality of the cutting sheet is not fully guaranteed.
4. Processing steps: Resin cutting sheets, especially large diameters and high thicknesses, or cutting sheets with strict dimensional tolerances are processed after hardening to ensure the geometrical dimensions and shape tolerances of the cutting sheets.
5, resin cutting sheet production formula, process parameters, raw hard sets.
Small size cutting piece, can be installed in electric angle grinder, large size cutting piece, can be installed in profile cutting machine. A cutting type thickened explosion-proof resin cutting piece, which is not easy to crack and burst when used, has high strength, can be used for grinding and polishing various workpieces, and can be used for cutting workpieces or materials, and cutting the sheet body in thickness It consists of 3~10 layers of elastic layer, each layer is 5~6mm thick. The layer is an abrasive layer between layers. The reinforcing ribs are distributed along the radial direction. The outer diameter of the wheel body is Φ200~Φ400mm and the thickness is 15~60mm. The pore diameter is Φ25~32mm; the elastic layer is glass fiber or nylon fiber filament sheet, the overall stability and strength are improved, the noise is reduced, the dust is reduced, the safety feeling is enhanced, the wear resistance is greatly improved, the cost is low, and the structure is simple. Therefore, it has broad application prospects.
