  • Between Centers And Centerless Grinding In One Setup

    15/11/2001· It's basically a centerless grinder that can perform between center OD grinding. In order to achieve a "2-in-1" process, a workhead and tailstock are installed at either end of the centerless grinder workrest blade. The workhead is equipped with a driver and programmable rotational speed. Both workhead and tailstock centers are retractable and adjustable to the workpiece length and diameter. AОнлайн-запрос

  • How It Works – Centerless Grinding | Today’s Machining

    For grinding round bar stock, a “through grinding” process is used. A bar of material, typically twelve feet long, feeds into the grinding machine between a grinding wheel and a regulating wheel. A carbide-tipped strip of steel, the work blade, supports the bar and holds it at the correct height, above the centerline of the grinding and regulating wheels. This is critical to the roundnessОнлайн-запрос
