Title: METHOD FOR MACHINING OF BALL TRACKS OF INNER RACES OF CONSTANT VELOCITY JOINTS
Abstract:
The present specification relates to a method for machining of ball tracks of an inner race of a constant velocity joint comprising the steps of providing a power skiving tool (1) having a plurality of cutting members and a first axis of rotation (Rt1), and a work piece (20) comprising an outer envelope surface (21) extending along an axis of rotation (Rwp), such that said first axis of rotation of said power skiving tool is arranged at a first distance from said axis of rotation of the work piece and oriented at a first angle (α) relative one another, applying a first rotational speed to said power skiving tool and a second rotational speed to said work piece and a relative movement between said work piece and said power skiving tool such that said cutting members engage said outer envelope surface to machine the ball tracks (22). The present specification also relates to a cutting insert and a power skiving cutting tool.
