Okuma has reason to celebrate: the company is marking its 125th birthday and has countless successes and memorable highlights to look back on. But looking ahead to the future is even more exciting, where even more sustainable and efficient solutions are top of the agenda. Okuma machines are available in the UK from NCMT.

“Okuma has always been a step ahead of trends and developments,” states Norbert Teeuwen, managing director of Okuma Europe GmbH. “The OSP open-architecture CNC is a good example of our innovative drive, as well as the internal and external automation solutions that enable us to respond to individual customer requirements with extreme precision.”

New solutions and further developments that increase customer efficiency will continue to be the main focus at Okuma moving forward.

“For decades now, we’ve been consistently working towards establishing our machines and processes on a sustainable basis, for example by optimising energy consumption or process flows for our customers,” says Teeuwen.

This commitment will become even more important in the future with national and international climate goals. Here, Okuma’s ‘Green Smart Machines’ will continue to support efficient manufacturing with reduced energy consumption.

“We focus on comprehensive solutions,” states Teeuwen.“Our customers can rely on us for a well-thought-out ‘all-in-one’ concept. Quality, precision, sustainability and efficiency are clear customer requirements that we fully meet. Our product development and services focus on individually developed solutions that precisely meet the respective demands.”

Okuma is also working towards CO2 neutrality within its own organisation. Energy savings or renewable energy from the company’s solar panel systems are already being implemented and expanded further.

For many gear manufacturers, power skiving is getting very interesting, and not without reason, since the technique is much faster than shaping and more flexible than hobbing and broaching. However, for many years, the technique was considered quite complex. Against this backdrop, Emag says that its new development is a game changer.

Firstly, with the VSC 400 PS, the operator makes only a few data entries, making power skiving very simple. Secondly, the VSC 400 PS can be equipped with up to four power skiving tools and six turning tools. As a result, the user can produce even complex components in a single clamping operation that is fast and controlled.

For example, the machine with its two spindles, which can hold up to two power skiving tools each, can produce up to four different types of external and internal teeth using four tools. A big advantage is that the gear tooth positions match perfectly to each other at the end of cycle, made possible by the single clamping operation and no change-over. The customary step of measuring the first tooth cutting pass (prior to cutting the second) is no longer needed.

Direct drives in the main and milling spindles keep the axes synchronised during the machining processes. Additionally, the rigid B axis allows a large variety of axis crossing angles. This is essentially the setting angle of the tool, which always tilts slightly with respect tothe component. It is this tilt that makes the actual cut possible. A value between 15°and 25° is common, but Emag has also successfully implemented power skiving processes with an angle up to 45°.

Advanced manufacturing – now: that is the motto of Chiron Group’s latest open house, which will take place on 10-12 May. The three-day exhibition in Tuttlingen, Germany, will focus on pioneering manufacturing processes that match user specifications, products and industries, including automotive, medical technology, aerospace andtoolmaking.

The guiding principle is the special combination of four attributes that characterise the future-oriented actions of the Chiron Group and influence how the company develops and offers tailored solutions to meet individual requirements: competent, smart, innovative, sustainable. These attributes are represented on the one hand by the six brands -Chiron, Stama, CMS, Factory5, Greidenweis and HSTEC – which are showing their specific or combined expertise at the open house.

Regarding machine highlights: mill-turn expertise taken a step further in the DZ 22 S mill-turn system 8 for the double-spindle machining of large volumes,or the complete machining of six sides with high autonomy using the MT 715 two+. Visitors can experience the full range of manufacturing solutions, from micro-machining with the Micro5 with a reduced environmental footprint, to maximum productivity per unit area when machining high-volume components for automotive oraerospace with the 22, 25 and 28 Series.

“In addition to showcasing exemplary pioneering machining processes for all industries, our main focus is on the lively dialogue with our guests,” emphasises Matthias Rapp, global head of marketing.

Each visitor will be personally attended and given an exclusive tour of the exhibition with targeted advice. And of course the event not only offers an excellent platform for experiencing this year’s motto ‘advanced manufacturing – now’, it is also an opportunity for inspiring exchanges, for example with catering and live music at the end of the second day of the exhibition.

Known as a ‘green’ joining technology for non-ferrous metals such as aluminium, friction stir welding (FSW) has established itself in a number of industries. In future, manufacturing companies using Heller machines will no longer need any additional hardware for this technology. Instead, they will be able to perform this process in a single set-up on their four-axis or five-axis machining centres.

FSW is a good choice when it comes to producing high-quality, cavity-free and tight welded joints with excellent fatigue properties. Accordingly, this process is often applied in the manufacture of reservoirs, tanks and containers, as well as in shipbuilding and aerospace engineering. In addition, FSW is increasingly establishing itself in the electrical industry and in automotive engineering with the growth of e-mobility, for the welding of battery housings.

Due to the comparatively low heat input, a very fine-grained structure results without cracks or pores in the material, while distortion in the component is minimal. The welded seam therefore meets the highest standards in terms of tightness and crash behaviour.

FSW also offers a number of key advantages with regard to the environment and health.Compared with conventional welding methods, there are no dangerous light flashes or hazardous fumes, for example.

The welding process becomes a particularly interesting technology with the successful integration into Heller machine tools. It allows users to eliminate an additional work step and only requires inexpensive tools, activation of the Heller technology cycle and the ‘adaptive control function’ in the Sinumerik 840D sl control.The machine operator can easily program the welding path at the CNC control panel using G code, while the transfer of CADCAM data is also possible without any problems.
