How much does the DMG Mori ULTRASONIC 55 MicroDrill cost?
Estimated price range
Our best estimate for a vertical machining centers (vmc) in this class — not a quote from DMG Mori. Configuration moves it a long way.
Overview
The DMG MORI ULTRASONIC 55 MicroDrill is listed as a machine for very small holes: a minimum hole diameter of 0.1 mm, a 32,000 min⁻¹ spindle and drilling force control below 1 N, on 550 × 550 × 510 mm (21.7 × 21.7 × 20.1 in) of travel. DMG MORI's current lineup does not include it, so it may be an older model, and the listed figures should be confirmed against the documents of the machine itself.
The three drilling figures belong together. A 0.1 mm tool breaks at loads a normal feed drive would never register, which is why force control below 1 N is listed alongside it. Even at 32,000 min⁻¹ a tool that small cuts at a low surface speed, so the process is slow per hole and depends on control more than on power. Internal coolant at up to 40 bar is listed, which helps clear chips from a hole that is deep relative to its diameter.
The work envelope is that of a small machining center. Workpieces up to 500 mm (19.7 in) in diameter and 400 mm (15.7 in) high are listed, with a table load of 600 kg (1,323 lb). The bed is listed as monolithic at 2,400 kg, mass that steadies a process in which the tool itself has almost no stiffness. The control is listed as Siemens SINUMERIK ONE.
No spindle power, torque, tool interface or magazine size appears in the listed figures, and neither does a positioning accuracy. For a machine bought to drill 0.1 mm holes, those are the first things to request.

Frequently Asked Questions
01
The listed minimum hole diameter is 0.1 mm, and the minimum tool diameter is listed as ø 0.1 mm. The spindle is listed at 32,000 min⁻¹ and internal coolant at up to 40 bar. The hole depth that can be reached at that diameter is not among the listed figures and depends on the tool and the material.
02
The listed figure is drilling force control below 1 N. A drill of 0.1 mm has almost no strength of its own, so the feed has to react to very small changes in load, for example when chips pack in the flutes or the drill breaks through. Holding the force under 1 N is what keeps such a tool from snapping.
03
Listed limits are 500 mm (19.7 in) in diameter, 400 mm (15.7 in) in height and a table load of 600 kg (1,323 lb). Travels are listed as 550 mm (21.7 in) in X and Y and 510 mm (20.1 in) in Z, so the X and Y travels are slightly larger than the maximum workpiece diameter.
04
It is not in DMG MORI's current lineup and may be an older model. The listed figures on this page, including the Siemens SINUMERIK ONE control and the 2,400 kg monolithic bed, should be checked against the documentation and configuration of the specific machine.
