The effective rake angle of a tooling system is determined by the insert geometry and the inclination of the insert in the toolholder. I \s (inclination angle) The angle is tilted around the corner cutting edge (S) parallel to the main cutting edge. Y (rake angle) This is the angle at right angles to the main cutting edge, measured with a smooth insert without chip breaker groove. In order to obtain the effective rake angle of the tooling system, the rake angle of the insert must also be taken into consideration. Walter Capto boring operations with turning toolholders for external machining Walter CaptoTM tools for external machining can also be used for internal machining of large diameters. This often takes place on mill-turn centers or automatic lathes. I Dmin Minimum internal machining diameter. Toolholder parallel to rotation axis. Dmin2 Minimum internal machining diameter. Toolholder 90° at an angle in relation to the rotation axis. X A 453 Technical information Turning WALTER Valenite Usage information Walter Turn turning tools effective rake angle
