Abstract
The profile turning tool is used for rough-turning and dressing circumferential and flat surfaces, in particular of workpieces made of light metals. It consists of a holder (10) with a receiver (16) for a diamond cutting head (18) as well as a claw (20), which is embodied as a chip breaker, engages a longitudinal groove (26) in the holder (10) and braces the cutting head (18) by means of a tightening screw (22). The groove (26) is located directly behind the cutting head (18). In longitudinal section, its base has an arcuate, concave shape and represents a pivot bearing for the claw (20) that has a correspondingly shaped underside and is guided on the lateral walls of the groove (26). The tightening screw (22) extends in front of the center of the arc with play through a hole in the claw (20).
Claims12
A profiled turning tool for rough-turning and dressing circumferential and flat surfaces on workpieces made of light metals, comprising of a rod-shaped holder (10) with a receiver (16) for a cutting element (18) with a rounded cutting head, whose cutting edge (42) is made of diamonds or cubical boron nitride and extends over a circumferential angle of more than 90°, and of a claw (20), engaging a longitudinal groove (26) in the holder (10) and having a front end (32) in form of a chip breaker, which claw clamps the cutting element (18) to the holder (10) by means of a tightening screw (22) being screwed into the holder (10), characterized in that the center longitudinal axis of the cutting head (18) extends in the longitudinal direction through the groove (26), whose base has a concave form in cross section and forms a pivot bearing for the claw (20), which is convexly shaped on its underside in the engagement area and is guided on the lateral walls of the groove (26), and that ahead of the center of the convexity, the tightening screw (22) extends with play through a hole (28) in the claw (20).
