Titanium Calls for a Tight Hold on the Tool
Haimer’s SafeLock System provides pull-out protection for tools in high performance cutting such as the machining of titanium.
Meeting the challenge of machining titanium effectively is the focus of many machine tool builders and cutting tool manufacturers. A common theme is “no missing links.” That is, a shop needs the right machine, cutting tool, programmed tool path, workholding setup and coolant delivery system to master titanium machining. Brendt Holden, president of Haimer USA (Villa Park, Illinois) would agree, except he’d add one more critical link to this chain of required elements—the right toolholder. Haimer USA’s parent company in Germany has developed a system specifically designed to address one of the problems encountered when applying high-performance cutting to titanium and other tough alloys. This system, called SafeLock, is designed to prevent a cutting tool from loosening and being pulled out of its holder. This situation could potentially scrap a very expensive aerospace part.
Choose cutters, depths and tool paths with attention to particular steps in the process, and you can machine titanium more efficiently than you might suspect. Boeing offers practical tips.
Achieving acceptable tool life and hole quality in a material such as CFRP demands a drill designed with composites in mind.
In carbon fiber reinforced plastic (CFRP), the material removal mechanism is shattering instead of shearing. This makes it different from other machining applications.
