Abrasive belt grinding features:

Because the sand belt of electrostatic sanding can ensure the uniform arrangement of the abrasive grains on the abrasive belt, the sharp end is outward, and a large amount of abrasive grains can simultaneously cut during processing; the longer circumference of the abrasive belt allows the abrasive to be well cooled; The belt is easy to adapt to different shapes of work, so the advantages of belt grinding are significant

1 High grinding efficiency:

The high efficiency of abrasive belt grinding is manifested in its high resection rate, grinding ratio (ratio of workpiece weight to abrasive wear weight) and machine power utilization. The known cutting belt grinding rate has reached 700mm3/mm·s for steel, even exceeding turning or milling. The grinding ratio of the belt is much higher than that of the grinding wheel, up to 300:1, even 400:1, and the grinding wheel is only 30:1. The power utilization rate of the belt grinding machine has reached 80% in the early stage of abrasive belt grinding. It is ahead of other machine tools, but today it is as high as 96%. In comparison, the grinding wheel grinding machine is only 52%, the milling machine is 57%, and the lathe is 65. %, so abrasive belt grinding is still a good energy-saving processing technology.

2 Process flexibility and adaptability:

Abrasive belt grinding is very convenient for grinding flat, inner and outer circles and complex surfaces. Designing a belt grinding head device as a functional component can be mounted on a lathe for rear grinding, or it can be mounted on a planer, and can also be designed into various special grinding machines. The size, length and width of the belt are also available in a variety of sizes, and are available in rolls, rings and many other forms.

3 Wide range of applications:

Abrasive belt grinding covers almost all engineering materials and surfaces of complex shapes. Today, belt grinding has been successfully applied to the grinding of difficult-to-grind materials such as various heat-resistant steels and titanium. Alloys, hardened steel, stainless steel, various difficult-to-machine cast irons and non-ferrous metals; non-metallic materials such as ceramics, marble, glass, etc.; special materials such as monocrystalline silicon, sapphire, ruby, etc.; complex profiles such as blades, cycloidal gears, etc. .

4 Good grinding quality:

The dimensional accuracy, shape accuracy and surface roughness of the surface of the workpiece ground by the abrasive belt are comparable to those of the same type of grinding wheel, while the quality indexes such as the chilling degree and residual stress of the surface layer are obviously improved, such as grinding with a belt. In the outer circle, the dimensional accuracy after finishing grinding can reach ±0.003～±O.O05mm, and the surface roughness RaO.2～0.63μm; the composite process combined with abrasive belt grinding and special processing can further improve the processing precision and surface. The quality, such as abrasive belt grinding and ultrasonic vibration combined with polishing the surface of the disk coating, the roughness can reach 0.O1μm; the degree of chilling and residual stress of the belt grinding is only 1/10 of the grinding of the grinding wheel.
