The flap disc is called an elastic grinding disc. It is made of plastic or fiber mesh cover and sandpaper sheets, and is suitable for angle grinders. There are generally 36 pages, 56 pages, 72 pages, and 90 pages. The particle size is generally between 40#-320#. The materials include brown aluminum oxide, zirconia fused alumina, silicon carbide, etc. It can be used for shipbuilding, automobiles, aviation, machinery, instruments, bridges, construction industries, and furniture. Various types of metal and non-metallic materials are rusted, painted, deburred, and welded.
The flap disc is composed of multiple sandpaper sheets glued to a tray in a fan-shaped stacking arrangement. The bonding angle between each sandpaper and the plane of the tray is 10°-30°. The arrangement of sandpaper in this utility model can make the sandpaper wheel achieve the best cutting angle when grinding and polishing the workpiece, ensuring that the substrate and grinding of the sandpaper wheel are consumed synchronously, significantly improving the overall wear resistance and grinding efficiency of the plane sandpaper wheel, and extending the service life of the sandpaper wheel. Grinding the surface of metal materials and non-metallic materials.
Features of flap disc:
The abrasive cloth can be imported or made domestically. The base material includes mesh cloth, nylon, plastic, steel paper, etc. The abrasive cloth is arranged in small pieces and evenly distributed in a fan shape to ensure the best grinding effect. The particle size is 36#-600#, with 60# and 80# being the most common. The outer diameter is 4"-7" and is installed on the angle grinder. It is used for grinding and repairing welds and burrs on the positive edge. It can be used interchangeably with the cymbal grinding wheel. It has the advantages of good elasticity, high efficiency, good heat dissipation and low noise. It is characterized by strong elasticity, high tensile bending strength and good grinding effect. It has fast grinding speed, good effect and low noise during grinding. It is suitable for major metal parts factories and machinery factories.
Scope of application of flap disc:
Flap disc is suitable for grinding and polishing of stainless steel, metal, metallurgy, automobile, wood, marble and other industries. Zirconia fused alumina (ZA) is particularly suitable for the processing of stainless steel and can replace resin-bonded grinding wheels. It has strong elasticity, high tensile and bending strength, good self-sharpening, high grinding rate and low noise. It is suitable for grinding welds and stamping flash inside the box.
The polishing flap wheel uses aluminum oxide as abrasive, and the base material is a cloth base made into gauze through an assembly line, and then the gauze is stacked and fully bonded with resin. The upper and lower grooves of the chuck are opened to fix the sand blade between the upper and lower chucks. The two ends of the inner side of the sand blade are respectively provided with an L-shaped buckle groove and a fastening ring. The fastening ring is fixedly connected with the buckle groove, and the fastening ring is cured and bonded with the buckle groove by glue to form a flap wheel.
Uses of flap wheels:
1. It can be made into grinding wheels with various characteristics, shapes and sizes, and has the widest range of uses.
2. It can be ground under a variety of grinding fluid conditions, and can also be used for dry grinding.
3. It can be made into grinding wheels with different pore sizes, such as large pores. Loose tissue grinding wheel. Used for slow feed grinding or grinding rubber products, etc.
4. The use speed of the flap wheel is generally below 35m/s, but it can also be made into high-speed grinding wheels of 50, 60, 80m/s or even 120m/s.
5. Suitable for forming grinding such as thread grinding, gear grinding, sample grinding, etc.
The flap wheel is generally used in various automatic, electric and manual grinding machines and polishing machines for grinding and polishing. The working surface is hard and wear-resistant, with strong elasticity, and has the characteristics of sharp cutting, high processing efficiency, no burns to the workpiece, stable physical and chemical properties, high safety, and simple and convenient continuous operation. It can save more time than manual grinding and is the best mass grinding product for surface treatment.
