  • Surface Hardening: Hard Turning or Grinding? | Gear

    1/10/2007· The grinding wheel is composed of many random irregular bonded abrasives, and therefore the machined surface has a random distribution of grinding marks In contrast, hard turning is performed by a geometrically defined cutting edge, and therefore the feed marks have a uniform spacing determined by the prescribed feed rate Surface profile measurement was carried out using a stylusIn fact, too much dust can cause the grinding wheel to wear too fast, so vacuum up excess dust Reduce the weight on the wheel or increase the surface area with more segments to reduce the weight per square centimetre Inspect your grinding discs regularly to make sure diamonds are exposed adequately and that it is not overheating Even the best discs will perform badly if used in the wrongGrinding United Diamond Tools
