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.”

Spanish Lathe manufacturer CMZ has consolidated its presence in France following the acquisition of industrial premises in Haute-Savoie. After opening its subsidiary CMZ France 20 years ago in Isère, this new space will be used to provide direct technical support, delivery of parts and advice on applications for CNC lathes. 

Part of CMZ’s international expansion strategy, the new technology centre will have a team of aftersales technicians to provide assistance in the area, as well as sales engineers who will offer direct advice for all customers. The facility will also house an applications engineering service and stock spare parts available on short lead times.

The facility’s permanent showroom for customers will display the full range of CMZ products and host technical workshops demonstrating the capacities of the lathes.

Benoit Branchu, a professional with a long career in the industrial sector will be heading the project. Throughout his career, Branchu has held a variety of posts which have given him in-depth knowledge on the use and operation of lathes, as well as a solid vision of the machining world. He did not hesitate to take up the lead in this new adventure in which Branchu is supported by a team of aftersales technicians for direct assistance.

Haute-Savoie is a strategic market for CMZ because the Arve Valley is recognised as the epicentre of precision turning in France and worldwide. The company has been operating in the area for just over a year and with this move is seeking to strengthen its presence with a strong, solid sales structure.
