· In this paper the preparation of honing stones by use of electrical discharge machining (EDM) is presented. The aim is to ensure an automatic, systematic and reproducible process of resetting the bond of honing stones. Different tool electrode materials were analysed systematically for two different bond specifications of the honing stones.

أكمل القراءة· This positioning of the dresser wheel axis at a 90-degree angle is the XING dressing technique. "For diamond wheel dressing, the dressing wheel still wears as much as or more than the grinding wheel, but now the dressing wheel is always a perfect radius," Mr. Drechsler says. "So that eliminates one of the huge variables in that process.".
