Recycling technique for CVD diamond coated cutting tools

Due to the thinness of the films produced by Chemical Vapor Deposition (CVD ), a cutting operation should be discontinued if the diamond-coated tool sh ows even a small amount of abrasion or wear on the substrate surface. For t hat reason, a recycling technique for CVD diamond-coated cutting tools is b eing sought with keen interest. In this paper, we propose a new technique f or recycling CVD diamond cutting tools by completely removing the worn thin film from the tool and then applying a new film to the de-coated surface, rme then performed durability-cutting tests and compared the results of a r e-coated diamond tool with a newly coated diamond tool. The effectiveness o f this technique was authenticated by the cutting tests. (C) 2001 Elsevier Science B.V. All rights reserved.
