Okuma plans numerous premieres at EMO 2025

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.

EMAG VL lathes in the Penn production chain

The increasing complexity of requirements in metal processing and international cost pressure pose particular challenges for manufacturing companies in high-wage countries. Austrian company Penn GmbH has established itself as an internationally active metal processor through a high level of vertical integration and consistent automation. Vertical turning machines from EMAG’s VL series, which have been in use at Penn for over a decade and have now grown to 43 spindles, play a key role in the production chain.

A milestone in the company’s history was the investment in a Hatebur forging plant at the Stratzdorf site in 2007, which produces rotationally symmetrical forgings at a rate of up to 70 components per minute. This corresponds to an annual volume of up to 10 million forged parts.

Such a high production volume requires equally efficient machining technology. This is where the machines from EMAG come into play, as managing director Gernot Penn explains: “The majority of our forged parts are then machined in-house. We use our connected EMAG VL manufacturing systems for this, which run practically around the clock.”

The EMAG machine portfolio has been systematically expanded over the years and

now includes over 30 EMAG VL 2 machines for machining small to medium-sized rotationally symmetrical workpieces, VL 2 DUO line machines with TrackMotion system for automated link-up, VL 3 DUO machines for larger workpieces, and VL 5i systems for machining complex geometries.

Penn plans to merge all three Austrian sites at the Stratzdorf location by 2028, which will mean a significant rationalization boost. EMAG machines will play an important role in this, as their compact design enables high productivity per unit area.

Nakamura releases new CNC multi-tasking lathe

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.

Transmissions manufacturer opts for Mills CNC

Mills CNC has supplied Sussex-based motorcycle transmission and gearbox design and manufacturing specialist, Nova Racing Transmissions, with a new DN Solutions Lynx 2100LMB lathe with FANUC control and an 8” chuck. The machine has replaced an older Daewoo lathe that, although still working satisfactorily, was slow and cumbersome to use.

Since installation, the Lynx 2100LMB, equipped with driven tooling capabilities, has been put through its paces machining a range of high-precision motorcycle close-ratio gearbox components (input/output shafts, gear blanks, dog rings, collars) in small batches up to 10-off. Customers include teams and riders competing in the British Superbike (BSB), World Superbike (WSBK), Isle of Man TT and Motocross championships, as well as motorcycle OEMs, motorbike racing clubs, and individual motorcycle owners, enthusiasts and engine builders. Components are also made for stock enabling the company to quickly supply customers with spare and replacement parts.

Input and output shafts are made from a tough and durable motorsport steel alloy supplied to Nova Racing in pre-cut rough bar stock from steel specialist, Bohler Steels. Following machine set up, soft turning operations undertaken on the Lynx 2100LMB start by first reducing the diameter and length of each pre-cut bar. With 50 mm diameter bars, for example, typically 1 mm is taken off the OD and 3 mm off the length. Other operations prior to heat treatment include gun drilling on each shaft’s centre line using high-pressure coolant to create a long narrow through bore hole with a high depth-to-diameter ratio.

There can be up to six soft turning operations performed on each shaft before heat treatment. Cycle times are short at 2-3 minutes.

Citizen unveils eco-friendly sliding-head lathes

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.
