In multi-spindle head-replacing type machine tool comprising a machining unit disposed on a base for advancing and retreating movements between an original position and a machining position, a first annular guide rail including a movable rail integral with the machining unit and a stationary rail to surround the machining unit which is located in the original position, a second annular guide rail disposed concentrically with and at a place axially offset from the first guide rail, a plurality of multi-spindle heads travellably carried on each of the first and second guide rails, first and second index mechanisms releasably connected respectively to the multi-spindle heads on the first and second guide rails for driving such multi-spindle heads for angular displacement, and an elevator mechanism disposed sideways from the first and second guide rails at a place offset from the movable rail for providing replacement of the multi-spindle heads between the first and second guide rails, a part of the stationary rail of the first guide rail and a part of the second guide rail are divided as lift rails in a circular arc at a place corresponding to the elevator mechanism, respectively, and the elevator mechanism comprises an elevator connected to each of the lift rails of the first and second guide rails, and lift-drive means connected to the elevator which is to be raised and lowered between the first and second guide rails.

Multi-spindle head-replacing machine tool

A replaceable gang head machine tool comprising a working unit having a driving motor mounted on a slide table adapted to be driven forwardly and rearwardly and an annular rail disposed on the machine base and carrying a plurality of gang heads adapted for being driven by an index table to selectively place a gang head in an operative position. A stockyard extends longitudinally adjacent the machine base and has a longitudinally extending runway guidably supporting a carrying truck for movement therealong and a plurality of replacement gang heads are disposed on the stockyard along the length thereof so that the replacement gang heads can replace the heads disposed on the annular rail by the carrying truck.
