磨削是目前半精加工和精加工的主要加工方法之一，砂轮则是磨削加工中重要磨具，砂轮一般安装在平面磨床、外圆磨床和内圆磨床上使用，也可安装在砂轮机磨刀机，万能磨刀机上刃磨刀具。

The fibre reinforced resin bond grinding wheel for cutting off is widely used. The traditional presses used for manufacture this type of grinding wheel in most factories at present have problems, such as laboriousness for workers, low efficiency of production, and dependance of products quality on operators' skillnes. This paper introduced a new type of press for shaping grinding wheel with six stations designed by the authors, considering the shortcoming of presses in use and the operating characteristics in manufacture of this type of grinding wheel.
