An Extremely Wide Application Range of Abrasive Belt

The superior grinding performance and flexible process characteristics of the abrasive belt determine that it has an extremely wide range of applications. From daily life to industrial production, abrasive belt grinding is used in almost all fields. The variety of application forms and the wide range are unmatched by any other processing method. The feature displays as below:

1. Abrasive belt grinding can grind almost all engineering materials

In addition to the materials that can be processed by grinding wheel grinding, it can also process non-ferrous metals such as copper and aluminum, and non-metallic soft materials such as wood, leather, and plastic. In particular, the "cold" grinding effect of abrasive belt grinding makes it more unique when processing heat-resistant and difficult-to-grind materials.

2. Abrasive belt grinding can process workpieces of various shapes with high surface quality and precision requirements

Abrasive belt grinding can not only process common plane, inner and outer surface workpieces, but also process large or special-shaped parts with high surface quality and precision requirements with extremely high efficiency.

For example: Polishing and grinding of large-area plates. The maximum width of the grinding wheel is only 1000mm, and the abrasive belt can be more than 2500mm.

The widest known abrasive belt grinder currently uses a abrasive belt width of 4900mm. In actual use, the common processing width of abrasive belt grinding is 50~2000mm, and the processing thickness is 0.4~150mm. Its productivity is as high as 1000m2/h. This wide abrasive belt grinding can be widely used for steel, stainless steel, silicon steel, aluminum, copper, particleboard, plywood, medium density fiberboard, leather, insulating board, ceramic board, as well as aerospace equipment, ships and nuclear physics research devices used for surface processing of various high-precision, low-roughness large plates, etc.

The precision machining of intermittent planes such as the section of the engine gearbox body can also be formed by grinding with a wide abrasive belt at one time, and it can ensure better sealing than the surface processed by traditional milling and planing.

3. Continuous polishing of metal abrasive belt or wire

Due to the development of wide abrasive belt grinding, the thin strip has the same grinding conditions on the entire width, so that the local stress will not be too large, resulting in stress deformation, so cold-rolled steel strip, copper, aluminum strip and the surface of alloy strip etc. are suitable for continuous polishing with abrasive belt. The processing width is 600~2100mm, the processing thickness is 0.1~2.2mm, the surface roughness value is Ra3.2~0.1mm, and the strip running speed is 3~80m/min.

Planetary belt grinding provides a very efficient and economical method of polishing coiled wire rods of stainless steel or other materials. The known wire polishing diameter is 0.8~20mm, and the continuous running speed is 6~150m/min.

4. The inner and outer circles of workpieces with a large aspect ratio of the abrasive belt are polished

In modern industry, it is very convenient to use abrasive belt grinding to process the outer circle of shaft workpieces with large aspect ratio and the inner circle surface of pipe workpieces. Generally, it can be achieved by adding an abrasive belt grinding device to a large standard equipment. For large batches, a special abrasive belt grinder can be used. Such as the outer circle of large generator rotors, rolls, paper dryers and other workpieces and the inner surface of cylinders, oil pipelines, pressure vessels and other workpieces.

Polishing of complex shaped workpieces. Forming and grinding of curved workpieces is difficult. However, the flexibility of the abrasive belt can easily process various complex curved surfaces, and the inner fillet with a radius of curvature of only 3mm can also be polished by the abrasive belt.
