METHOD OF GROOVING SUPERALLOYS AND CUTTING INSERT THEREFOR |
摘要 |
<p>A method of grooving a work-piece of superalloy uses a grooving cutting insert at least partially covered with a Cubic Boron Nitride (CBN) layer and having one or more interior ducts formed therein which open out to the insert's rake face at one or more corresponding openings. One or more coolant fluid streams, conveyed via these interior ducts at a pressure of no less than 200 bars, are directed upwardly and outwardly toward an interaction area between a cutting edge of the cutting insert and the work-piece, to thereby limit lengths of work-piece chips created during the grooving operation. The openings of the cutting insert's interior ducts may be located between 0.5-3.0 mm from the insert's cutting edge.</p> |
