LEMAN concrete cutting wheels Development Status

To solve these problems, scientists and technicians have been studied from various aspects, including the performance of low-temperature ceramic vitrified diamond grinding cement mass memory and the key factors affecting the development. Therefore, the study of high-strength, low-temperature, low thermal expansion depressed center cutting wheel coefficient and excellent performance of low-temperature ceramic adhesive is home to pottery wheel materials research. 
Tanaka T, EsakiS, Nishida K, etc. by selectively increasing the number of holes in the wheel and size, you can make self-sharpening wheel materials set times can be further improved. Jackson MJ, Barlow N, Mills B super hard materials by controlling the pore structure inside the pottery wheel, so that the production of grinding wheels with high bond strength, good grinding efficiency and cooling performance when grinding. 
Vitrified started on Toughening studies, such as binding agents for glass ceramics processing phase, adding an appropriate amount of suitable binders whiskers. They found that the addition of boric acid binding agent in silicon whiskers, one can suppress the generation of prevent at 100 ° C ~ 200 ° C when leaving the wheel due to the rapid expansion of the volume of cracks; hand whisker whisker itself can serve to enhance the effect to improve the tensile strength of the binding agent. 
Because when vitrified diamond abrasive combination of factors such as difficulty coefficient is relatively large, vitrified bond diamond wheels development and production has been hampered. I overcome the technical challenges of vitrified diamond, first in the domestic production of vitrified diamond grinding wheel with gems, and develop a variety of wheel size, has been favored gem processing field. In recent years, research and development of grinding PCD / PCBN cutting tools vitrified diamond grinding wheel, grinding PDC vitrified diamond grinding wheel series cutting disc for inox vitrified diamond grinding wheel in the market has a good reputation.
