Experimental Study on the Cutting Temperature with Micro-Texturing Self-Lubricated Tools

Micro-texturing self-lubricated cutting tools named MTR-1 and MTR-3 were designed and made based on micro-texturing lubricating idea and laser micro-texturing technology. Dry cutting tests on 45 # hardened steel were carried out with these self-lubricated cutting tools and conventional cemented carbide tools named MT0. The cutting temperatures and the morphology of chips were measured. The results indicated that the cutting temperatures with the micro-texturing self-lubricated cutting tools were reduced compared with that of MT0 cemented carbide tools, and the chip coiling was improved.
