  • Preparation and performance of resin-bonded

    2020-1-1  Grinding performance was also tested by mounting the wheels in a lathe tool (WAZA520X-NC, Lapmaster SFT). A piezoelectric dynamometer (9527B, Kistler) was used to monitor grinding forces. After continuous grinding for 6 h, both the workpiece and grinding wheel were cleaned, dried, and weighed to determine the grinding ratios.
