ABSTRACT:
In a vertical type of double disc surface grinding machine, an object of this invention is to enable simple adjustment of a parallelism between a grinding surface of a lower grinding wheel and a work end face clamped by a clamping jig of a rotary table, even when a grinding wheel spindle axis is disordered. The vertical type of double disc surface grinding machine is equipped with a pair of grinding wheels2&3opposing each other in vertical direction and fixed to a pair of vertical grinding wheels4&5and a rotary table15holding a work W and supplying it to a grinding position A1located between the grinding wheels2&3, and provided on the rotary table15with a work clamping jig17including a rotary shaft63which clamps the work W at a specified position and makes it spin itself. The table15and a bed14supporting its drive mechanism are supported by plural supporting legs12adjustable in their heights, so that front-to-back and right-to-left inclination angles can be adjusted in relation to horizontal level, and the supporting legs12are installed on a slide bed11slidable in horizontal direction.
