The CTX 2500|700 universal turning machine has been unveiled by DMG Mori. Designed for machining components up to 366 mm in diameter from billet, or 76 mm from bar, and to a maximum length of 705 mm, the machine is the first in the company’s range that allows users to turn grooves up to 12 mm wide in CK45 steel and drill holes to 80 mm diameter.
DMG Mori’s CTX 2500|700 combines the rigid machine bed and box guideway configuration of the NLX 2500|700, of which more than 10,000 have been sold, with the VDI turret and Siemens 840D Solutionline control from the CTX beta 800. DMG Mori’s proprietary app-based control and operation interface, CELOS, is included.

Precision and surface quality derive from the thermo-stability of the lathe, which has a spiral oil jacket around the spindle to control temperature and coolant recirculation through the cast bed. A linear scale with a standard resolution of 0.01 µm is fitted in the X axis for positional feedback. Furthermore, rapid traverse of 30 m/min in the linear axes ensures short idle times, while a Y axis may be specified for turn-milling work.
The TurnMaster 4000 rpm main spindle with 26 kW of power and 525 Nm torque (or optional 3500 rpm, 30 kW, 1194 Nm version) is opposed by an 11 kW, 7000 rpm, 70 Nm (or 32 kW, 5000 rpm, 360 Nm) counter spindle. A 6000 rpm, 32 Nm cooled-disc turret with VDI 40 interface is offered as standard, while an 85 Nm TorqueDrive and a 12,000 rpm SpeedDrive are available.

The LNS Group says that it is implementing e-Connect solutions to integrate its products, particularly barfeeds, into customer ERP and MES systems. “This will allow LNS customers to get full machining transparency at a glance, including the workload of each machine, cycle times and expected production completion,” explains Carlos Muniz, global product manager barfeed at the LNS Group.

LNS has been pushing innovation in the field of connectivity for more than 10 years. Together with major machine manufacturers, the connection between the peripheral and the machine tool was developed. A second major innovation was the connection between the LNS product and the humans controlling it. Monitoring production remotely from mobile devices saves time by knowing when the machining process will stop for a changeover, thus anticipating downtime in production planning. Thanks to e-mail or GSM notifications, overall production processes are more efficient. Additionally, the connection to internal or external technical support ensures downtime reduction.
While the e-Connect solutions to the machine and people are essential, another major step is the integration into customer ERP, MES and quality control operations.
“Until now, such systems and the machines were not efficiently connected, missing transparency,” says Muniz. “LNS is developing software drivers that will gather relevant information from the peripheral and, through middleware, feed it to applications or systems such as ERP, MES or quality control. These solutions are tailor-made for each customer software platform. The real-time monitoring of all processes will help clients to save time and resources.”

The next-generation Y-axis, sub-spindle Doosan Puma 2600SY Mk II turning centre series is now available from Mills CNC. Although the new machines are equipped with a 10” chuck, unlike Puma 2600SY Mk I models, they have a larger 81 mm bar diameter capacity. The machines are also supplied with built-in type spindles (as opposed to belt-driven spindles), which generate less vibration during cutting operations.

Further innovations include six strategically positioned heat sensors that automatically monitor and compensate for any thermal displacement during machining operations. In addition, the spindles feature a reconfigured bearing structure comprising two angular-contact bearings and two taper roller bearings to improve C-axis positional accuracy and spindle runout (less than 6 µm).
The Puma 2600SY Mk II uses high-performance NTN material (as opposed to Turcite) on its box-guideway axes, a move that is said to result in improved and more responsive movement, and reduced wear. Other performance improvements include a revised design of milling turret that incorporates a Curvic coupling piston structure delivering up to 12% additional clamping force; improved durability of the Y-axis carriageway; and a spindle air-purge function that helps prevent chip and coolant ingress.
The machine was exhibited for the first time in the UK at the recent Mills CNC open house, which took place in October.
