Linear motored CNC universal ups output
10%
Offering an output increase of at least 10%, when compared with previous machines, universal lathes with a linear motor powered X-axis include the fastest turret in the market.
DMG (UK) has introduced the CTX 320 and 420 linear universal CNC lathes that offer a production output of at least 10% higher than conventional CNC machines The increase results from using a dynamic linear drive in the turret carriage X-axis and the high speed Siemens 840D Powerline CNC with ShopTurn

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.
ShopTurn is a Windows-based, shop floor programming system that includes extensive 3D functions.
It controls the fastest turret in the market, a fast tailstock as well as direct measuring systems in all axes.
The linear drive in the X-axis produces high rapid traverse speeds and accelerations/decelerations.

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.
Contact-free power transfer makes for a wear-free construction of the drive train - a benefit particularly in tough, multi-shift operation.
The Siemens 840D CNC Powerline stands for a performance increase of over 100% in the CNC and PLC areas.
The ShopTurn user interface and 3D functions allows complex workpieces with face and shell machining operations to be generated very quickly, using interactive, context-sensitive operator guidance and integrated 3D simulation.
These functions can be used without any DIN/ISO knowledge on the part of the operator.
Additionally, ShopTurn makes machine set-up easier through intuitive tool management for the turret and practice-orientated support for workpiece introduction and measurement.
The performance of the integrated spindle drive, offering impressive acceleration/deceleration capabilities, is no less impressive.
It takes only 1 sec to go from zero to 5000 rpm, and again, to return to zero.
Main spindle torque is 270Nm (at 100% duty cycle) for the CTX 420 - some 12.5% higher than its predecessor.
DMG offers the CTX 320/320 in a number of configurations.
These begin with a 12-station turret for static tools and a tailstock.
There is a version with 12 driven tooling stations in the turret, also a version with driven tools in a Y-axis and machines with a counter-spindle, driven tooling and an optional Y-axis can also be supplied.
Swing diameters on the CTX 320 and 420 linear are 400mm and 680mm respectively.
X-axis travels are 450mm and 635mm.
A hydraulically powered moving tailstock is an option, with 0.5m/min traverse speed or a NC tailstock has a traverse up to 20m/min.
A fast indexing turret has an indexing time, station-to-station, of 0.15 sec.
In all, the CTX linear series offer idle time reductions of up to 40%.
Other details include: CTX 320 linear and 420 linear, respectively: drive outputs are 16 and 25kW; rapid traverse in X, Y and Z are 60, 10 and 45m/min; bar diameters are 50mm and 65mm; chuck diameters (Y-axis/counter spindle) are 210mm (160mm) and 260mm (185mm); longitudinal travel is 450mm and 635mm and Y-axis (optional) is +/-32mm and +/-40mm.
