Positional adjusting mechanism for a cutting insert
First Claim
1. A tool for chip removing machining, comprising:
- a tool body including a seat for receiving a cutting insert;
a first hole formed in the tool body adjacent the seat, a support surface formed in the tool body adjacent and above the seat;
an insert-adjusting bushing mounted in the first hole and including a second hole therein, the bushing having a slotted upper end including at least a first bushing portion facing the seat and a second bushing portion facing the support surface;
the support surface arranged to abut the second bushing portion and urge the bushing in a direction laterally relative to an axis of the first hole to eliminate lateral play between the bushing and the first hole, thereby stabilizing the bushing; and
an adjusting screw mounted in the second hole for displacing the first portion of the stabilized bushing toward the insert seat.

Abstract
A positional adjusting mechanism for a cutting insert in a tool for chip removing machining, preferably a milling cutter. The positional adjusting mechanism includes a hole formed in the tool body adjacent to the cutting seat which receives the cutting insert. A slotted bushing is mounted in that hole. An adjusting screw is received in the bushing to expand an upper end of the bushing. In the mounted state of the bushing in its hole, contact occurs between an upper part of the bushing and a support surface of the tool body which urges the bushing laterally in its hole to eliminate lateral play and thus stabilizes the bushing.

15. A method of mounting an adjustable cutting insert of a tool for chip removing machining, comprising the steps of:
-
A) inserting a bushing into a first hole of a tool body such that a first bushing portion at an upper end of the bushing faces an insert seat of the tool body and a second bushing portion at the upper end of the bushing engages a support surface situated above and adjacent to the first hole such that the bushing is urged by such engagement in a direction extending laterally of an axis of the first hole to stabilize the bushing;
B) attaching a cutting insert to the insert seat; and
C) advancing an adjusting screw within a second hole formed in the stabilized bushing to wedge apart the first and second bushing portions, whereupon the first bushing portion laterally displaces the cutting insert.
