With 960 m² of efficiency and precision, Okuma Europe says it will transform EMO 2025 (Hanover, Germany, 22-26 September) into a showroom with live machining demonstrations that include European and world premieres.

Okuma customers will already be familiar with the LB4000 EX III horizontal lathe, but they will now have the opportunity to experience its full configuration versatility for the first time at EMO 2025. During the trade fair, the machine will be exhibited with milling tools, an additional Y axis and an optional sub-spindle. The latter enables automatic workpiece transfer and complete machining within one machine.

Among the 13 machines that Okuma will present at EMO are several enhanced classics, each demonstrating its advantages in any production environment. These include the Multus U3000 multi-tasking machine, which can perform complex machining operations with precision. This is made possible by flexible five-axis machining on the main and sub-spindles, a large workspace, and a tool magazine that accommodates up to 120 tools. A second turret also reduces cycle times and increases productivity.

Various processes will be demonstrated live on the machine at the booth, including friction stir welding. This technology enables the seamless joining of components, increasing flexibility and productivity by eliminating the need for external processes.

Efficient automation is also a key factor in the success of one of Okuma’s best sellers. The company says its LB3000 EX III is considered one of the most advanced horizontal lathes for the precise machining of individual parts and small to medium-sized batches. The machine’s built-in Armroid automation solution, with an extended gripping range, boosts its productivity even further.

Nakamura-Tome Precision Industry has introduced a new CNC multi-tasking lathe named NTY³-150V. The machine is the fourth model in the V series, following the WY-150V introduced in October 2024, and is specifically designed for high-speed performance. It features several new technologies as standard, including ChronoCut software, which reduces idle time during machining for a productivity boost of up to 30%.

The NTY³-150V is a three-turret machine capable of mounting tools on up to 72 stations. By pre-setting tools for two or three workpieces beforehand, there is no need to change tool set-ups when processing different workpieces. Moreover, adjusting the left-right time balance and utilising the lower turret for centre support – along with the flexibility of machining processes that can be designed – adds to the appeal of three-turret machines.

Nakamura-Tome’s NTY³-150V is the first in its class to offer a spindle capable of handling 80 mm diameter bar capacity, with the option of equipping a motor of up to 28/15 kW. Additionally, the milling motor features a standard output of 7.5/3.7 kW, with maximum rotation speed increased to 10,000 rpm. This capability enables the high-speed machining of large-diameter workpieces while maintaining both high rigidity and precision.

Notably, when one turret is retracted in the Z-axis, the other turret can advance beyond its Z-axis reference point, ensuring a larger travel in this direction. Thanks to the crossover travel capability, each turret can move into the opposite side’s machining area. This enhances flexibility by making it easier to use the upper turret for long workpieces or operations involving long tools.

For machining parts from bar up to 20 mm in diameter (optionally 25 mm), a third generation of the Cincom L20-LFV series of sliding-head lathes with a considerably uprated specification has been launched by Citizen Machinery UK. Now offered in five variants, VIII, IX, X, XII and XIIB5, the L20-LFV is a best-selling model with platen tooling as well as front and rear tool posts. All stations feature driven and static positions on the top three models, which also have additional Y-axis movement of the sub-spindle.

Simultaneous five-axis control for performing complex machining cycles is supported on the top two models, one of which has a B-axis tool post with optional ATC (automatic tool change) for tools up to 30 mm in diameter. Chip-to-chip time is 4 seconds. Cutters are driven by a 2.2 kW motor at up to 12,000 rpm, so even small diameter mills are capable of productive metal removal rates.

The Japanese manufacturer says it was the first to offer B-axis ATC on a sliding-head lathe to extend the machine’s versatility when executing angled cross-working or end-facing operations. The magazine accommodates 12 tools, while a 13th is fixed in the upper position on the live tool unit.

Another feature contributing to the lathe’s versatility is the ability to switch over quickly between Swiss-type operation and non-guide bush turning for more economical production of shorter components. This mode results in less bar wastage due to the shorter remnants.

The machine incorporates Citizen Machinery’s Eco II suite of energy-saving features, designed to optimise power consumption, reduce compressed air usage, minimise CO2 emissions and promote environmentally friendly manufacturing practices.

Whether for food, beverages, pharmaceuticals, chemicals or water, anywhere liquids are processed will typically see a separator or a decanter at the heart of production. At GEA Westfalia Separator Group’s largest production site in Oelde, Germany, where 1900 people are employed, 120 centrifugal separators are produced every month with the help of 15 machine tools supplied by DMG Mori. These include turn-mill centres and five-axis machining centres and with a high degree of process integration.

One of the latest machines to be installed is a CTX gamma 3000 TC multi-tasking, twin-spindle, B-axis CNC lathe with MATRIS robotic loading and unloading, which supplies spindles to the drives production department in Oelde.

Various spindles undergo production, requiring combinations of turning, gear milling, deep-hole drilling, grinding and in-process measuring. The previous production route involved separate milling machines, turning centres and a cylindrical grinding machine, so work-in-progress and inter-machine handling were inherent in the process. The CTX gamma 3000 TC integrates all of the processes, including grinding, into one work area. Throughput times are considerably shorter and the original machines are free to perform other production tasks.

“The biggest advantage is the fully automated production of entire batches,” says Dennis Hartmann, head of industrial engineering in the Separators Business Unit. “The MATRIS system is designed to be served via four component pallets that are wheeled by pallet truck in and out of the loading area. The robot takes the raw parts and aligns them so that they can be clamped correctly in the chuck and steady rest. The finished parts are then placed back on the pallet.”
