Studies on High-efficiency and High-precision Machining of Difficult-to-cut Materials by PVD Coated Tools (2nd Report)

Cutting Temperature of TiCN-Coated End Mills Deposited by UBMS Method

Abstract

The UBMS (UnBalanced Magnetron sputtering) method is applied to the coated end mills and some kinds of such tools are used in high-speed milling of SUS304. This coating film is designed to improve lubricating ability rather than heat resistance. Lower cutting temperature is measured with these UBMS-type TiCN-coated tools than the ordinary AIP-coated tools in high-speed side milling without coolant.
