CNC lathes offer stability and power

Price-competitive, two-axis slant bed CNC lathes feature a special one-piece, thermally balanced bed that promotes powerful and stable operation.
The Taiwan Takisawa EX Series of two-axis slant bed CNC lathes now available from Ward CNC of Sheffield, UK, boast a level of high-performance that is unrivalled for machines in this class. Coupled with the use of a special one-piece, thermally balanced bed that promotes powerful and stable operation, the machines' four-track super rigid precision linear guideways and high-speed servo turret all combine with the Fanuc 21iT CNC to provide users with an exceptional 'Japanese quality at Taiwanese prices' package. With swings over the bed of 350mm and 400mm, the EX-106 and EX-108 models have crosslide travels of 280mm and 320mm, respectively, and between centres distances of 455mm and 645mm.

Standard turning diameters are 190mm and 216mm, respectively, and with 152mm and 203mm chucks the machines have respective maximum turning diameters and lengths of 240mm and 320mm, and 350mm and 530mm.

Bar capacities are 43mm for the EX-106 and 52mm for the EX-108, and spindle speeds range from 50-5,000 rev/min (5.5/7.5kW motor) and 60-4,000 rev/min (7.5/11kW) for the two models which both have 12-tool turrets.

Auto tool setting arm, parts catcher, swarf conveyor and programmable quill tailstock are standard; collet chucks and bar feed systems can be provided as options to further widen the machines' cost-effective production capabilities.

Precise CNC lathes intended for 'entry level'

To bring efficient and precise turning to the 'entry-level' user, CNC lathe control system offers visual user-interface and 3D-realtime simulation.
Both the NEF 600 - an EMO 2005 world premiere - and the established NEF 400, make efficient and precise turning possible for the entry-level user, with the highest technology and the latest high-tech components. The user can take advantage of a high level of flexibility, maximum precision and dynamics in the production process. Numerous options allow customised configurations of the machine, to reach maximum productivity in manufacturing.

For decades, the NEF brand has represented lathe-technology at the highest level, ease-of-use and an excellent cost/performance ratio.

With such a successful history, expectations were high when Gildemeister developed the fourth generation of this entry-level machine, which is a high-tech and affordable alternative to low-cost Asian suppliers.

The result is as impressive as it is convincing: both the NEF 400 and the larger NEF 600, which will be presented for the first time at the EMO in Hannover, offer a large number or high-tech components and an overall performance that is unprecedented in the sector of universal turning, making it especially unique.

The impressive innovations of this machine are apparent in the pivoting DMG SlimLinePanel with a stainless steel design, a 15in TFT-screen, high-tech CNCs from Fanuc or Siemens, both with visual user-interface and 3D-realtime simulation, as well as rotational speeds of 4,000 rev/min.

with a drive power of up to 24kW and 720Nm torque.

Another feature unique in this class is the 30 deg slanted bed with four-track design for optimal chip disposal and excellent accessibility.

In addition, the NEF machines feature a large work area combined with a traversable steady-rest and a fast 8x-turret, for high productivity and flexibility.

Chuck workpieces with diameters up to 350mm.

(NEF 400) or 600mm.

(NEF 600), and shaft workpieces with lengths up to 650 or 1200mm can be machined in the shortest possible time.

All this is achieved with the highest level of precision and with excellent surface quality, ensured by digital drive technology for the main spindle and sturdy linear guide-ways.

Additional features of this pioneering machine series are the tailstock with hydraulic quill, low space requirements of the fully enclosed machine in Space Green design (Metallic optional), advanced state-of-the-art central lubrication and integrated safety technology (Safety Integrated/Dual Check Safety).
