The problem of increasing the efficiency of manual grinding of high-quality and artistic glass by increasing the wear resistance of the bond and decreasing the relative consumption of diamonds is considered. It has been established that in diamond wheels for grinding high-quality and artistic glass, it is advisable to use binders with tungsten carbide powder and cobalt powder. Adding tungsten carbide powder to the binder in an amount of 10% leads to a decrease in the relative consumption of diamonds by 15 - 20%, and the addition of 10% cobalt powder to the binder leads to a decrease in the relative consumption of diamonds by 45 - 50%. In this case, the roughness of the treated surface does not deteriorate. Currently, new circles are successfully working at 35 enterprises in the Czech Republic and Slovakia.
