AI Description
BetaCapabilities
The DMG Mori Ultrasonic 20 is a compact, high-precision 3-axis CNC milling machine ideal for detailed metalwork. With a 40,000 rpm spindle, 0.001mm accuracy, and 30 m/min feed rate, it excels at producing small to medium-sized components with tight tolerances. The modest 200×200×190mm travel makes it perfect for intricate parts rather than large workpieces.
Industries & Uses
This machine serves jewelers, medical device manufacturers, aerospace suppliers, toolmakers, and precision engineering shops. It's commonly used for prototyping, small-batch production, and custom metal components where accuracy matters. Startups and job shops appreciate its compact footprint and proven reliability—it fits into smaller workshops while delivering professional-grade results.
What to Check When Buying
When evaluating this unit, prioritize the spindle condition despite the recent 2023 overhaul; verify documentation of that service. Check the Siemens 840D control system for responsiveness and any error messages. Inspect the table and guide rails for play or scoring, and run test cuts to confirm the stated 0.001mm accuracy. At 4,979 operating hours, wear is moderate but expected—ask about regular maintenance schedules and any repairs beyond the spindle work. Request a pre-purchase inspection to verify thermal stability and coolant system function.
