Abstract
A double surface machining system for machining both side surfaces of a workpiece comprises, in an operational state, a pair of upper and lower spindle heads to be vertically positioned and driven, respectively, a pair of upper and lower spindles provided for the upper and lower spindle heads, respectively, in parallel to each other, to be rotatable about horizontal axes thereof, the upper and lower spindles having front ends to which tools are mounted, respectively, a pair of upper and lower workpiece supports for supporting the workpiece therebetween, which are vertically positioned and driven on one side of the upper and lower spindle heads as viewed from a workpiece feed direction, respectively, and another pair of upper and lower workpiece supports for supporting the workpiece therebetween, which are vertically positioned and driven on another one side of the upper and lower spindle heads as viewed from a workpiece feed direction, respectively. According to this structure, both the side surfaces of the workpiece are subjected to machining working simultaneously by the tools mounted to the respective spindles with being supported by the paired workpiece supports on both the sides of the spindle heads.
