New and re-sharpened tools from Star SU feature Balinte Alcrona Pro, an ALCr-based coating developed by Oerlikon Balzers that is said to provide better heat and wear resistance than other aluminum-based coatings.
According to the company, lower thermal conductivity enables the coated tools to work well in low-temperature applications and enables faster hobbing speeds. The coating also is said to produce lower tool costs, longer tool life, faster cutting parameters and 100-percent dry cutting—all of which lead to production cost savings.
