Overview
The DMG Mori ULTRASONIC 65 2nd Generation is a large-format universal 5-axis machining center with integrated ultrasonic technology, designed for manufacturers machining medium-to-large advanced ceramic, glass, and composite components. With 735 x 650 x 560 mm (28.9 x 25.6 x 22 in) of travel and 1,000 kg (2,205 lb) table load capacity, this machine handles workpieces that exceed the ULTRASONIC 50 envelope.
The ultrasonic vibration system carries over from the rest of the ULTRASONIC lineup, superimposing longitudinal oscillation onto the rotating tool to reduce process forces by approximately 50% on hard and brittle materials. This enables productive 5-axis machining of zirconia, alumina, silicon carbide, glass, sapphire, and CFRP composites at feed rates and depths of cut that would fracture parts without ultrasonic assistance.
Spindle options reach up to 30,000 RPM with HSK-A63 interface, with torque up to 430 Nm (317 ft-lb) depending on the spindle configuration. The HSK-E50 ultrasonic actuator system is available for direct ultrasonic activation through the spindle interface. The wide spindle range allows shops to optimize for their specific material mix.
Maximum workpiece diameter reaches 840 mm (33.1 in) with a height of 500 mm (19.7 in). Tool magazine capacity extends to 180 pockets. The machine footprint covers approximately 12 square meters (129 ft2), and crane loading capacity reaches 1,500 kg (3,307 lb).
The CELOS platform with SIEMENS control runs ULTRASONIC-specific technology cycles for adaptive vibration parameter optimization. For manufacturers requiring both ultrasonic-assisted machining and conventional 5-axis milling on larger workpieces, the ULTRASONIC 65 provides a versatile platform that handles advanced ceramics and conventional titanium aerospace parts.

Strengths & Limitations
Strengths
- 1,000 kg table load capacity handles medium-to-large ceramic and composite components beyond the ULTRASONIC 50 range
- Up to 30,000 RPM spindle with HSK-A63 interface provides high surface speeds for finishing ceramics and glass
- 180-tool magazine supports complex multi-operation parts with both ultrasonic and conventional tooling
- Ultrasonic vibration reduces process forces by 50% for productive machining of hard-brittle materials
- 840 mm max workpiece diameter accommodates large ceramic and composite components for aerospace and energy
- Dual capability for both ultrasonic-assisted and conventional 5-axis milling on a single platform
- 12 m2 footprint is compact for the work envelope and capability level
Limitations
- Price premium over conventional 5-axis machines of similar size requires consistent hard-brittle material work to justify
- HSK-A63 and HSK-E50 ultrasonic tooling adds ongoing cost compared to standard tooling
- Heavier and more complex than the ULTRASONIC 50, potentially overbuilt for smaller workpieces
- Ultrasonic actuator system adds maintenance complexity beyond standard spindle maintenance
- Limited to SIEMENS control platform

Frequently Asked Questions
01
New ULTRASONIC 65 2nd Generation machines typically run $550,000 to $900,000 depending on spindle configuration, tool magazine size, and automation options.
02
The ULTRASONIC 65 offers 13% more X-travel (735 vs 650 mm), 25% more Y-travel (650 vs 520 mm), over 3x the table load (1,000 vs 300 kg), up to 30,000 RPM spindle (vs 20,000), and 180-tool capacity (vs 120). Choose the 65 when workpiece size or weight exceeds the ULTRASONIC 50 limits.
03
Yes. With ultrasonic deactivated, the machine functions as a high-performance 5-axis machining center with up to 30,000 RPM and HSK-A63 tooling. Shops regularly use the ULTRASONIC 65 for both ceramic/composite parts and conventional aluminum or titanium machining.
04
Up to 430 Nm (317 ft-lb) depending on the spindle configuration selected. This allows moderate roughing in metals alongside ultrasonic machining of ceramics.
