Abstract
In a multiple spindle processing unit which can change processing locations of a work in accordance with a modification made to the work, the present invention is intended to facilitate changes of design corresponding to the modification made to the work and reduce the number of parts to be replaced. In a frame member which is guided and supported so as to be moved towards and away from a work, insertion holes are formed at a plurality of locations corresponding to processing locations of the work. In each of a plurality of tool main spindle assemblies, a main spindle having a front end portion where a chuck for mounting a tool is provided is coaxially journaled in a housing in the shape of a circular cylinder or a polygonal cylinder and is rotationally driven by a built-in motor. Each of the tool main spindle assemblies is mounted to the frame member with the housing inserted through the insertion hole. The tool main spindle assembly may be mounted to the frame member through a holding plate which is divided into a plurality of portions for securely sandwiching the housing or through a flange which is integrated with the housing and which protrudes radially.
