CUTTING TOOL HAVING A BIDIRECTIONAL ADJUSTMENT MECHANISM

摘要

A cutting tool having cutting inserts (40) retained in cartridges (18). The location of each cartridge (18) is adjustable by a bidirectional adjustment mechanism having an adjustment screw (54) directed in the direction of adjustment. The adjustment screw(54) has a head(62) and a flexible flange(64) with an annular recess (60) therebetween. A protuberance (72) projecting from the cartridge (18) engages the annular recess (60) with an interference fit thereby coupling the adjustment screw(54) to the cartridge (18). As the adjustment screw (54) is screw rotated about its axis of screw rotation (8) it moves along the axis of screw rotation (8) taking the cartridge (18) with it. Screw rotation of the adjustment screw (54) in opposite senses results in the adjustment of the position of the cartridge (18) in opposite directions. Due to the fact that the protuberance (72) is firmly located in the annular recess (60) of the adjustment screw(54) play or backlash is eliminated.
