Overview
The DMG Mori ULTRASONIC 85 2nd Generation is the largest machine in the ULTRASONIC lineup, designed for manufacturers machining the biggest advanced ceramic, glass, and composite components that require ultrasonic-assisted 5-axis machining. With 935 x 850 x 650 mm (36.8 x 33.5 x 25.6 in) of travel and 1,500 kg (3,307 lb) table load capacity, this machine handles large workpieces that exceed the ULTRASONIC 65 envelope.
The ultrasonic vibration system reduces process forces by approximately 50% when machining hard and brittle materials, enabling productive 5-axis machining of zirconia, alumina, silicon carbide, glass, sapphire, and CFRP composites at feed rates that would cause fracture without ultrasonic assistance. The HSK-A63 interface with ultrasonic actuator integrates vibration directly into the toolholder.
Spindle speeds reach up to 30,000 RPM, providing the surface speeds needed for high-quality finishes on ceramic and glass components. Maximum workpiece diameter reaches 1,040 mm (40.9 in) with a height of 590 mm (23.2 in), accommodating large ceramic turbine shrouds, armor panels, and optical components.
Tool magazine capacity extends to 180 pockets, matching the ULTRASONIC 65. The machine footprint covers approximately 12 square meters (129 ft2), the same as the ULTRASONIC 65 despite the larger work envelope, making it a space-efficient upgrade for shops that need more travel and load capacity.
The SIEMENS control with CELOS platform runs ULTRASONIC-specific technology cycles for adaptive vibration parameter optimization. The machine also functions as a high-performance conventional 5-axis machining center when ultrasonic is deactivated, providing versatility for shops with mixed material requirements.
For manufacturers at the cutting edge of advanced ceramics and composite materials, the ULTRASONIC 85 provides the largest dedicated ultrasonic 5-axis platform available. The combination of 1,500 kg table load, 1,040 mm workpiece diameter, and 30,000 RPM spindle with ultrasonic capability makes this the machine for large-part applications in aerospace CMC, defense ceramic armor, and industrial ceramic wear parts.

Strengths & Limitations
Strengths
- 1,500 kg table load capacity handles the largest ceramic and composite components in the ULTRASONIC lineup
- 1,040 mm max workpiece diameter accommodates large ceramic turbine shrouds, armor panels, and optical components
- Up to 30,000 RPM spindle with HSK-A63 ultrasonic actuator provides high surface speeds on hard-brittle materials
- 935 x 850 x 650 mm travel offers the largest work envelope in the ULTRASONIC series
- 180-tool magazine supports complex multi-operation parts with diverse tooling requirements
- Same 12 m2 footprint as the ULTRASONIC 65 despite 27% more X-travel and 50% more table load
- Dual capability for ultrasonic-assisted and conventional 5-axis milling on a single platform
Limitations
- Highest price in the ULTRASONIC lineup requires consistent large-part ceramic and composite work to justify
- HSK-A63 ultrasonic tooling represents ongoing specialized tooling cost
- Larger and heavier than the ULTRASONIC 65, more machine than needed for smaller workpieces
- Ultrasonic actuator system adds maintenance complexity and cost
- Limited to SIEMENS control, no HEIDENHAIN option available

Frequently Asked Questions
01
New ULTRASONIC 85 2nd Generation machines typically run $650,000 to $1,050,000 depending on spindle configuration, tool magazine options, and automation.
02
The ULTRASONIC 85 offers 27% more X-travel (935 vs 735 mm), 31% more Y-travel (850 vs 650 mm), 16% more Z-travel (650 vs 560 mm), and 50% more table load (1,500 vs 1,000 kg), all within the same 12 m2 footprint. Maximum workpiece diameter increases from 840 to 1,040 mm.
03
For shops that machine both advanced ceramics and conventional metals, yes. With ultrasonic deactivated, the ULTRASONIC 85 functions as a capable 5-axis machining center with 30,000 RPM and HSK-A63 tooling. However, shops doing purely conventional metalcutting would get better value from a dedicated 5-axis platform.
04
Maximum workpiece diameter is 1,040 mm (40.9 in) with a height of 590 mm (23.2 in) and weight up to 1,500 kg. This covers most large-format ceramic components including turbine shrouds, armor panels, and industrial wear components.
