Development Direction of Abrasive Belt Grinding

Abrasive belt manufacturers think that compared with the conventional processing methods, abrasive belt grinding is a kind of high quality, high efficiency and low consumption of new processing method. At the same time, for some long axis with poor rigidity or thin-walled sleeve parts, it is feasible to design and manufacture some abrasive belt grinding devices with simple structure, easy fabrication and convenient operation, installing on the general machine tools instead of grinding machine for efficient finishing.

At abroad, abrasive belt grinding technology is developing in the following directions:

A. It increases machine tool power constantly, and more than 200kw of abrasive belt grinding machine has emerged.

B. It improves the speed of abrasive belt, and is developing abrasive belt grinding machine with high speed more than 100m/s.

C. It increases the width of abrasive belt and improves the efficiency of processing, and the widest one has amounted to more than 4.9m.

D. It prolongs the life of abrasive belt and has increased from 2-4h to 8-12h.

E. With the dosage of grinding of abrasive belt grinding increasing, the grinding quantity per unit has already met the cutting amount per unit time of common metal-cutting machine tool. Thus, it has pushed abrasive belt grinding in a new stage and new trend of milling instead of grinding.

With the abrasive belt grinding technique widely used in the domestic construction machinery industry, and developing and perfecting of abrasive belt manufacturing process, there will be more abrasive belt grinding machines and devices. Predictably, abrasive belt grinding technique is sure to get the attention and further development they deserve in engineering machinery manufacturing industry.
