Our best estimate for a 5-axis machining center in this class — not a quote from DMG Mori. Configuration moves it a long way.

Overview

The DMG MORI ULTRASONIC 65 puts ultrasonic machining on a monoBLOCK frame: 735 mm (28.9 in) of X travel, 650 mm (25.6 in) of Y and 560 mm (22 in) of Z, with a workpiece limit of 840 mm (33.1 in) in diameter, 500 mm (19.7 in) in height and 1,000 kg (2,204.6 lb).

DMG MORI describes the monoBLOCK concept as stability from one casting, with a one-piece column, FEM optimization of all components and clamping of the swivelling rotary table. The clamp counts in positioned work: with the table locked at an angle, a roughing cut pushes against the clamp and not against the drive. The machine stands on a three-point support, which the manufacturer says makes it quick and easy to set up.

Workpiece weight is the figure to read closely. The technical data limits the workpiece to 1,000 kg (2,204.6 lb) at up to 840 mm (33.1 in) in diameter. The diameter is larger than the 735 mm X travel because the rotary table presents each side of the part to the spindle; height is the tighter limit at 500 mm (19.7 in). DMG MORI lists several table solutions, one for 5-axis machining and one for complete machining with milling and turning, so establish which table a quotation includes and what it is rated for.

The ultrasonic function uses an HSK-A63 / HSK-E50 actuator system with automatic frequency detection, amplitude regulation and automatic feed adjustment. DMG MORI states up to 50% reduced process forces, which it links to higher feeds, better surface finishes and longer tool life. The spindle range goes up to 30,000 rpm, and the tool magazines are integrated into the machine. Comprehensive cooling measures, a high-performance coolant unit and multi-sensor compensation are standard; an optional precision package is listed with 15 % higher precision.

The ULTRASONIC 85 is the next size up, with 935 mm (36.8 in), 850 mm (33.5 in) and 650 mm (25.6 in) of travel.

Strengths & Limitations

Strengths

Workpieces up to 1,000 kg (2,204.6 lb) and 840 mm (33.1 in) in diameter
monoBLOCK construction from one casting with a one-piece column and clamping of the swivelling rotary table
Comprehensive cooling measures, a high-performance coolant unit and multi-sensor compensation as standard
Table solutions for 5-axis machining or for complete machining with milling and turning
Ultrasonic actuator system for HSK-A63 / HSK-E50 with up to 50% reduced process forces
Spindle range with up to 30,000 rpm

Limitations

Maximum workpiece height is 500 mm (19.7 in), well under the 840 mm (33.1 in) diameter limit
The 15 % precision gain belongs to an optional precision package
The Highlights state no standard spindle speed or power for this model, only that the range goes up to 30,000 rpm
The capacity of the standard tool magazine has to be taken from the quotation

Best For

Heavy parts for ultrasonic machining, up to 1,000 kg (2,204.6 lb) Wide, low workpieces within 840 mm (33.1 in) diameter and 500 mm (19.7 in) height Positioned roughing with the swivelling rotary table clamped Combined milling and turning with the mill-turn table solution

Frequently Asked Questions

01 How heavy a workpiece can the ULTRASONIC 65 carry?

The technical data gives a maximum workpiece weight of 1,000 kg (2,204.6 lb), for a part up to 840 mm (33.1 in) in diameter and 500 mm (19.7 in) high. DMG MORI lists more than one table solution, so have the load rating of the table on your quotation confirmed in writing and include the fixture in the total.

02 What are the travels of the ULTRASONIC 65?

735 mm (28.9 in) in X, 650 mm (25.6 in) in Y and 560 mm (22 in) in Z. The 840 mm (33.1 in) maximum workpiece diameter is greater than the X travel because the rotary table turns the part, so the far side is machined after indexing.

03 What does the monoBLOCK concept mean on this machine?

DMG MORI's Highlights describe it as stability from one casting. The listed elements are a one-piece column with large, stable slideways, FEM optimization of all components, and clamping of the swivelling rotary table. The machine rests on a three-point support for setup.

04 Which ultrasonic tool interfaces does the ULTRASONIC 65 support?

Technology integration is through an HSK-A63 / HSK-E50 actuator system. The system detects and adapts the frequency automatically, regulates the amplitude and adjusts the feed automatically. DMG MORI states up to 50% reduced process forces with it.

05 How does the ULTRASONIC 65 compare with the ULTRASONIC 85?

The ULTRASONIC 85 is larger in every axis: 935 mm (36.8 in) in X, 850 mm (33.5 in) in Y and 650 mm (25.6 in) in Z, against 735 mm (28.9 in), 650 mm (25.6 in) and 560 mm (22 in) on this machine. Choose by part size, and by whether the 1,000 kg (2,204.6 lb) limit here is enough.
