DMG Mori ULTRASONIC 50

The DMG Mori ULTRASONIC 50 is a universal 5-axis machining center with integrated ultrasonic technology, bridging the gap between the precision-focused ULTRASONIC 20 linear and the larger ULTRASONIC 65/85 platforms. With 650 x 520 x 475 mm (25.6 x 20.5 x 18.7 in) of travel, this machine handles medium-sized advanced ceramic, glass, and composite components that exceed the ULTRASONIC 20 work envelope.

The ultrasonic vibration system superimposes longitudinal oscillation onto the rotating tool, reducing process forces by approximately 50% when machining hard and brittle materials. This enables productive machining of zirconia, alumina, silicon carbide, glass, sapphire, and CFRP composites with conventional diamond tools at feed rates that would cause fracture without ultrasonic assistance.

Spindle options include the speedMASTER at 15,000 RPM with 21 kW (28 hp) and 111 Nm (82 ft-lb) in the standard configuration, with a high-power option at 46 kW (62 hp) and 200 Nm (148 ft-lb), and a 20,000 RPM option at 35 kW (47 hp) and 130 Nm (96 ft-lb). The B-axis swivels from -35 to +110 degrees for full 5-axis access to complex part geometries.

Maximum workpiece diameter reaches 630 mm (24.8 in) with a height of 500 mm (19.7 in) and table load capacity of 300 kg (661 lb). The tool magazine holds 30 tools standard, expandable to 60 or 120 pockets for complex multi-operation parts.

The SIEMENS control runs ULTRASONIC-specific technology cycles that automatically adjust vibration amplitude and frequency based on the cutting conditions, tool type, and workpiece material. This adaptive control reduces the operator skill required for ultrasonic machining and ensures consistent results across production runs.

For manufacturers working with advanced ceramics and composites in the medical, aerospace, semiconductor, and optical industries, the ULTRASONIC 50 provides a versatile mid-size platform that handles both ultrasonic-assisted machining and conventional 5-axis milling on the same machine.
