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.
What does "jerk" refer to, and where does it fit into machine performance?
Accuracy is not just inherent to the machine—it also depends on how the machine is used. Try these techniques to let a new or existing CNC machining center achieve its potential precision.
The recipe for best results is simple: Start with a rigid machine, add a high pressure through-the-spindle coolant system, then combine these with the right drill geometry plus the right speeds and feeds.
