Ultrasonics and milling make hard
machining easy
For micro, precision machining of carbide, glass and ceramics, a linear motor ultrasonics system combines hard machining of advanced materials and conventional HSC-milling on a single machine
Micro, precision machining of carbide, glass and ceramics is now in demand in a range of sectors Tool and mould making, electrode manufacturing, medical and optical technology, watch making, the sensor and semiconductor industries and aerospace are typical customers for this technology And it is to meet their specific needs that DMG has introduced its new Ultrasonic 20 linear

Dies milled dry at high speeds
The new DMC 65 V vertical machining centre applies high-speed cutting, dry machining and universal application in die making and series production with high dynamics and precision.
CNC miller-drillers cut 20% off machining times
With the highly productive DMU 50 / 70 eVolution, DMG has added a new dimension to universal milling and drilling machines designed to save up to 20% on machining times.
The Ultrasonic 20 linear combines hard machining of advanced materials and conventional HSC-milling on a single machine and offers exceptional performance.
Its wide-ranging capability allows this new addition to be used to machine materials that could not previously be considered.
For example glass materials such as germanium, mono- and poly-crystalline silicone present no problem to this machine; nor do carbon fibre, carbide, sapphire, ruby, mother of pearl or agate, the list is considerable.

Gildemeister lathe programme covers all
The lathe programme run by the GILDEMEISTER group has now become so extensive that there really is no machining job any more that these machines cannot do.
Conventional lathe has digital drives
The world innovation - the NEF 320 K - a conventional lathe with navigator system rounds off successful NEF product line.
Linear drives provide 1.4G acceleration in X, Y and Z, a positioning accuracy of +/-2.5 micron/0.0001in., and a repeat accuracy of as little as +/-1micron/0.00004in.
Excellent surface quality Ra < 0.2micron - is assured.
The option to expand the machine for three to five axes working, with a torque motor in the C-axis and servo motors with free-float transmission in A, brings unrivalled flexibility.
The Ultrasonic 20 linear benefits from exceptionally fast tool exchange thanks to the new Ultrasonic Aktor system based on a modified HSK fitting.
This allows the use of both ultrasonic and conventional tools on the same water-cooled, 40,000 rev/min USB spindle.
The 16-station automatic tool changer - optionally 32 - can accommodate milling tools from 0.1 to 16mm and grinding tools from 0.1 to 30mm in diameter.
The cast mineral monobloc base provides excellent vibration absorption and stability.
On the standard machine the Y-portal is made from aluminium but as an option it can be of carbon fibre for even higher rigidity, lower weight, reduced thermal expansion and acceleration up to 2G.
A further option is a three-chamber coolant system with slurry tank.
Major beneficiaries of this technology are expected to be tool and mould makers.
For example on the Ultrasonic 20 linear embossing tools can be made from carbide in a single process without the need for die-sinking.
Equally, threaded bores of H6 quality can be introduced into carbide moulds opening up an entirely new range of possibilities.
