Abstract

The present invention relates to a mechanism for enhanced, bi-directional fine adjustment of cutting insert cartridges in machine tools. A cutting insert cartridge for chip removing machining tools has an axial adjustment system threadedly engaged with a cartridge body and a tool body. The axial adjustment system includes a differential screw in threaded engagement with the tool body either directly, for example by threaded engagement with a threaded openingin the tool body, or indirectly, for example by threaded engagement with a cross dowel fastener slidably positioned in an opening in the tool body. Actuation portion positioned axially between threaded end portions of the differential screw has an engagement feature on an outer surface to be driven, e.g., with a tool or by hand, to rotate the differential screw and adjust the axial position of the cartridge. The spaced apart relationship improves access to the actuation portion and engagement feature for rotation of the differential screw. Chip removing machining tools with such cartridges, methods of adjusting the position of the cartridge and cutting insert adjustment differential screws are also disclosed.

Description

technical field [0001] The present disclosure relates to chip removal machining tools for cutting workpieces. More specifically, the present disclosure relates to a mechanism for bi-directionally adjusting the position of a cutting insert cartridge relative to the body of a chip removal machining tool using a differential adjustment screw having opposed threaded ends at a first The ends interact with the threaded formation and at the second end with the threaded portion of the cartridge, and an actuation portion having an engagement feature on the outer surface is interposed between the threaded ends. The present disclosure relates to toolholders and adjustment mechanisms, as well as chip removal tool and toolholder combinations, and differential adjustment screws themselves. Background technique [0002] In the following discussion, reference is made to certain structures and / or methods. However, the following references should not be construed as an admission that these ...
