With the new CTX 450 and CTX 550, DMG Mori presented at EMO last month the two larger sister models of the CTX 350 introduced previously at Open House Pfronten 2023. The CTX 450 and CTX 550 feature a main and counter spindle, as well as a Y axis with 130 mm of travel, to facilitate the complete six-sided machining of complex workpieces. A turning diameter of 480 mm and a turning length of 800 mm, or 1225 mm for the CTX 550, offer maximum flexibility for customers.

The CTX 450 and CTX 550 reflect DMG Mori’s four pillars of process integration, automation, digital transformation and green transformation. It is possible to automate this six-sided complete machining in various ways – for example with the Robo2Go or the Matris systems. App-based control with a 24″ multi-touch screen simplifies digitisation on the shop floor, while modern drives such as the synchronous spindle motors ensure energy-efficient operation.

The CTX 450 has a main spindle offering 4000 rpm and 360 Nm. The main spindle of the larger model achieves 770 Nm at 3250 rpm. In addition, the counter spindle has a speed of 5500 rpm and a torque of 192 Nm (CTX 550: 4000 rpm and 360 Nm). The turnMASTER spindle concept with three (ISM80) or four bearings (ISM102) ensures precision, supported by a large bar capacity (80 or 102 mm).

Positioning accuracy in the C axis is 0.001°. Among the options is a direct-drive turret with speed of up to 10,000 rpm and torque of 42 Nm.

WFL Millturn Technologies presented two turning-boring-milling machines at EMO 2023 in Hanover last month: the M50 MILLTURN/3000 mm and the M80X MILLTURN/4500 mm. WFL machines are available in the UK from Kyal Machine Tools.

Visitors could experience the M80X live with a demonstration of gear shaft machining, including measurement of the gear teeth. Both machines feature a new design and come with the Sinumerik ONE control.

The M80X MILLTURN with 4500 mm machining length and 1000 mm turning diameter features a grinding attachment and a vibration-damped Silent Tools Plus boring bar. Visitors could see the machine’s capabilities for themselves with a live machining demonstration involving a gear shaft measuring 800 mm in diameter and 1824 mm in length. During the demonstration, the machine produced gear teeth using WFL FLANC cycles.

On the M50 MILLTURN/3000 mm, WFL provided live machining of a power generation shaft, as well as turbine blades and fir tree, impeller and generator shaft profiles. The demonstration workpiece had a diameter of 600 mm and a length of 2355 mm.

WFL turning-boring-milling machines now feature Sinumerik ONE from Siemens with its new user interface. The new machine control is modern and user-friendly, while the integrated SIMATIC S7-1500F PLC enables PLC cycle times that are up to 10 times faster than its predecessor. Boasting a selection of innovative functions, Sinumerik ONE optimises machining speed, contour accuracy and machining quality. According to WFL Millturn, Sinumerik ONE makes machine tools more productive and therefore faster, more flexible and more efficient.
