The Grinding Rate and Specific Cost of Internal Plunge-Cut Diamond Grinding of Hardmetals with Periodic Electrical Discharge Actions

摘要

The authors have studied the influence of diamond wheel grain size on the grinding rate and specific cost of internal plunge-cut elastic-mode grinding of VK15 (WC-15Co). Periodic electric-discharge actions on the wheel working surface, with an optimal cyclicity, provide an 396% improvement of the grinding rate and an 305% reduction of specific cost in comparison to grinding performed with no such actions.
