ABSTRACT:
A method and apparatus for achieving accurate axial tool adjustment in an automatic turret-type screw machine which avoids the necessity of loosening the barrel tightening screws on the tool mount for axial tool adjustment and provides micrometer adjustment for the tool as well as a gauge for reset of the tool in replacement after breakage or re-grinding. A rough-adjustment tool back-stop is provided which subsequently moves with the micrometer adjustment. A tool locking collet arrangement is provided which can be moved with the back-up screw against spring tension to assure solid tool clamping while permitting micrometer controlled axial motion for initial set-up and tool replacement.
