  • Cutting: abrasive belt grinding

    introduction: The grinding of the workpiece surface is made using a high-speed ring abrasive belt。It is generally carried out on the abrasive belt grinder。figure1 Abrasive belt grinding method It is a method of grinding the outer circle and plane of the belt。The sand belt surrounds the pressure wheel and tension wheel with certain elasticity﹐Continuous cutting motion is driven by rotary press wheel﹐The workpiece is placed on the conveyor belt or work table for feed movement。When the workpiece touches the sand belt or passes through the grinding zone under the press wheel﹐A layer of material that has been removed from the surface by an abrasive strip。The cutting speed of abrasive belt grinding is generally20~30meter/seconds﹐Grinding pressure is2
