From SETCO Precision Spindles
"I can't be giving ya Warp 9 speed much longer, Mr. Spock. These engines are beginning to show signs of stress!" The chief engineer for the Starship Enterprise-Star Trek's Scotty-might have been as wary about today's ever increasing spindle speeds. These critical elements of the high-speed machining system are under duress from industries like aerospace, where shorter manufacturing lead times are preferred on large aluminum parts that formerly took a long time to machine. Imagine a machining center topping off at 6,000 rpm yesterday...and 100,000 rpm today! And with no loss in quality and reliability.
Wherever in-between lies the truth, the fact is that precision cutting tools are digging into metal at faster speeds than ever before, five to 10 times more than conventional machining, according to some experts. This puts the onus on spindles, along with their motors and bearings, to provide the necessary torque, rigidity, and accuracy.
