Studies on High-efficiency and High-precision Machining of Difficult-to-cut Materials by PVD Coated Tools (1st Report)

High-speed Milling of SUS304 with Coated End Mills Deposited by UBM Sputtering Process

Abstract

The UBM(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. Long tool life and good surface quality are obtained with these UBM-type coated tools than standard commercially available coated tools in high-speed side milling without coolant.
