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.
