Adjustable lead angle chamfering toolholder |
摘要 |
An adjustable lead angle toolholder is disclosed for selectively cutting a workpiece at 30 DEG , 45 DEG , or 60 DEG angles. The toolholder may have a rotatable, cylindrical endmill body that includes a radially-oriented wall or a stationary, square shank having a planar wall on its distal end. The toolholder further includes a cutting insert having at least one linear cutting edge, and a mounting assembly for pivotally mounting the insert onto the wall of the endmill body such that a lead angle of the linear cutting edge is adjustable with respect to the outer periphery of the toolholder body. The mounting assembly includes a plate-shaped insert holder, and a fastener for pivotally connecting the insert holder to the wall of the toolholder body. A locking screw secures the plate-shaped insert holder at a selected pivoted position on the wall of the toolholder body. The invention allows a single toolholder to cut or chamfer a workpiece at different angles.
