Video: Linear Motor Micromachining Center
The AZ150 “nano precision” vertical machining center from Sodick uses a 120,000 rpm air-turbine spindle. Linear motor drives are controlled with 3-nanometer resolution, the company says—enabling the machine to produce parts with finishes down to 0.6 RMS.
The machine achieves machining accuracies of 100 nanometers or smaller—in some applications down to 5 nanometers. Axis travels are 6 x 6 x 4 inches, with a maximum work weight of 11 pounds. The spindle uses HSK-E32 shrink-fit toolholders.
Though it won’t replace high speed machining, Boeing sees “low speed machining” as a viable supplement to higher-rpm machines. Using new tools and techniques, a shop’s lower-rpm machining centers can realize much more of their potential productivity in milling aluminum aircraft parts.
Hand-scraping the mating surfaces of a CNC machine tool’s motion system offers myriad advantages.
Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
