Depending on countries, it is easier to find h11 quality bars than h7 or h8 dedicated to high precision turning (not to mention the price difference). To guide this material is not easy and to be able to rely on a very flexible guide bush that adapts to this type of material is very interesting. Walter Dünner presents a new four positions rotating unit. Meeting in Moutier with Daniel Dünner the director of the company.
The DunnAir four position rotating unit is a pneumatic device developed to fit precisely the machines. It incorporates a standard Airflex guide bush. With this system, the same guide bushes can be mounted on several types of machines. Adjustment of the guide bush being fully performed by the front, manipulation is reduced and simplicity is maximum.
4 positions for more subtlety The 4 positions rotating unit includes the classic positions of clamping and opening plus two guiding positions with different settings. Mr. Dunner explains: "According to the operations to be performed, guidance must be more or less tight and up to today, we still had to work with a “compromise guide bush”. With the DunnAir, it is possible to manage the forces according to the various operations”. Simply driven by M functions, this device opens new perspectives for high precision turning. Not only it offers the opportunity to work with less precise material but finely adapts to the different operations to achieve.
We will come back on this new unit and guide bush soon!

After the takeover of Kummer Frères by Precitrame Machines, an analysis of the K5 product showed that it still had too many teething problems to be marketed in volume. This triggered the immediate development of a new generation of micromachine, which was eagerly awaited by the microtechnology industry. This modernisation also makes it possible to integrate new functions and options requested by the markets. Standalone machines In its simplest form, the K5 range is a single machine that (…)
Wickert Maschinenbau unveils the world’s fastest heating-cooling press at JEC World in Paris. The composite press with a heating platen size of 600 x 600 mm and a pressing force of 25 t excels with heating and cooling rates of up to 50 K/min. Standard presses are available for temperatures up to 450 ºC. Their main application is the processing of high-performance thermoplastics in the aerospace industry, but they are also used to manufacture membrane electrode assemblies (MEA) for fuel (…)
SINUMERIK ONE, the digital native CNC with new technological functions and a redesigned user interface, is already being used successfully on EMCO turning and milling machines. The advantages of this new generation of controls are obvious: straightforward access to the world of Sinumerik ONE (95% operational compatibility with Sinumerik 840 D sl) as well as optimised machining speed, contouring accuracy and machining quality with innovative technological features. SINUMERIK ONE with (…)
Based on the motto "Precision Engineering meets Digitization", the HAIMER Group will demonstrate at AMB 2022 in Stuttgart (Hall 1, Booth F50) and at IMTS 2022 in Chicago (West Hall, Booth #431510) how modern tool management works: with high-quality, process-reliable components, with continuous digitization for fully automated tool presetting and secure transmission of digital tool data all the way to the machine tool. The HAIMER Group, world market leader for tool shrinking and balancing (…)
A new version of the OPC UA for Machine Tools Companion Specification has recently been released. The Joint Working Group of the OPC Foundation is supported by the VDW and has produced a supplement that now makes it possible to integrate existing inventory systems. The collection of important operating data and KPIs gives rise to further advantages. Dr. Wilfried Schäfer, Executive Director of the VDW, is pleased with the progress: "The update of the specification for machine tools sees us (…)
Arburg has optimised the software for its Freeformer machines so that, in future, all water-soluble Armat support materials can be applied in a grid structure that is optimised for Arburg Plastic Freeforming (APF). This will shorten build times in the APF process by up to 55 per cent – while also reducing material consumption. The water-soluble support material can then be washed out without manual finishing work. "At the rapid + tct 2022 trade fair in Detroit, USA, we will be (…)
