TOOL HAVING ULTRA-FINE CUTTING BLADE AND PROCESSING TOOL HAVING ULTRA-FINE CUTTING BLADE

摘要

PROBLEM TO BE SOLVED: To provide a preferable processed surface in which a heat generated during processing is cooled by a cooling liquid retained in a streak groove and having little thermal damage. ;SOLUTION: A tool has a processing acting surface 12 formed by providing a large number of fine streak grooves 11 on a surface of a tip selected from a diamond, CBN, WC, a cemented carbide, a high speed steel, ceramics of other hard materials. A tool having an ultra fine cutting blade 1 is constituted by forming an ultra-fine cutting blade on a position divided by the streak grooves 11. Further, the tool is provided with a basement rotatably disposed and at least one tool having an ultra-fine cutting blade 1. The basement constitutes a holder and retains the tool having an ultra-fine cutting blade 1.;COPYRIGHT: (C)1999,JPO
