Milling Titanium Faster on Light-Duty Machines

hen bidding large titanium jobs with a lot of stock removal, you’d better get everything right, from the bidding numbers to the actual machining rates. Otherwise you may either lose the
TEM owner Dave King (seated), Ingersoll’s Dave Gradie and TEM shop supervisor Mike Brown put their heads together on plant-wide retooling of light-frame 40-taper mills with Ingersoll’s new high-feed Hi Quad face mill. On difficult titanium, TEM is running five times faster than is possible with conventional tools. Mike is confident it will work as well on difficult stainless steel and save TEM upwards of $500,000 a year.
bid or end up waving goodbye to a bundle of bucks when the parts actually run. TEM Inc., a progressive 40-man shop in Buxton, ME, sure has gotten it right with a fleet of 34 light-duty CNC mills running 16/5 machining titanium. TEM rough mills an airframe forging literally five times faster than is possible with conventional cutters—on a light-frame CNC with a 20-hp (14.9-kW) spindle. The key is high-feed milling with a 3" (76-mm) Hi-Quad-F mill from Ingersoll Cutting Tools (Rockford, IL), featuring an improved PVD surface coating on the inserts. TEM completes the parts in just five hours, compared with 26 hours with conventional mills or 10 hours with competing high-feed cutters.
Unlike a lot of Maine-coast job shops, TEM serves a national client base which includes stainless steel work for oil and gas companies. So the company has been all too familiar with milling high- temp metals for years and has had decent success with some older Ingersoll high-feed mills in those applications.
