Como quintuples output with Tschudin Cube

Thanks to the efficiency of the Tschudin Cube 350 centreless grinding machine, Como Industries has quintupled the output of pin gauges with very small diameters.

“It changes our way of working completely,” states Sophie Demesse, CEO of Como Industries.

Headquartered in Courbevoie near Paris, the company produces pin gauges, hydraulic nuts and other high-accuracy parts for well-known customers such as Airbus, Michelin, Thales Group and Safran.

“On the old machine, we needed five hours to manufacture 100 pin gauges of very small diameter to a tolerance of 1.5 µm,” explains Demesse. “With the Cube 350 we need only one hour – a huge productivity leap.”

The new grinding machine convinces not only with speed, but also with its optimised quality.

“Before, we were not able to reach the same kind of precision when it comes to diameters between 10 and 20 mm,” she says. “Thanks to the Cube 350, we no longer need an extra finishing step, which boosts our efficiency. For us, it’s important to stay one step ahead of our competition in Europe, but also in Asia. The co-operation with Tschudin allows us to do so.”

The grinding experts of Tschudin AG and the team of Como Industries will take part in the AMB exhibition in Stuttgart on 13-17 September. Visitors can inquire about the successful co-operation, exchange views with Demesse, Tschudin shareholder Urs Tschudin and CEO Iwan von Rotz, and of course witness the compact, award-winning, three-axis CNC centerless grinding machine on stand 5 in hall 5C11. In addition, Tschudin will exhibit another Cube 350 with robot and a 400 ecoLine centreless grinding machine.

Perfect surface finishes for prosthetic parts

Ottobock in Duderstadt, Germany, a €1bn turnover manufacturer of orthopaedic systems, recently commissioned two new mass finishing systems from Rösler. The equipment is now in place at a factory in Blagoevgrad, Bulgaria, which opened in 2021.

For planning and building its tenth and largest manufacturing facility, this global health-tech company paid special attention to efficient and sustainable operations. As a result, the company specified a specially developed Keramo-Finish process, an energy-efficient dryer and a centrifuge for cleaning and recycling the process water.

The Keramo-Finish operation replaces an acid-based process for creating a high-gloss polish. This includes the utilisation of a porcelain polishing media in combination with a special paste and a brightening compound. The new, acid-free process allows the complete recycling of process water, which not only results in a significant decrease in water and compound consumption, but also a sizable cost reduction.

The polishing operation takes place in a new R780 EC vibratory bowl. Here, the special shape of the processing bowl creates a homogeneous flow of the media/workpiece mix, ensuring that workpieces are quickly polished and separated in an efficient and gentle manner.

Ottobock achieves the same operational benefits with its second new vibratory bowl, an R420 EC model. Together with specially selected media and compounds, Ottobock is using this machine for a broad spectrum of applications ranging from deburring and edge radiusing, to surface smoothing.
For the eco-friendly cleaning and recycling of process water, the two mass finishing machines connect to a semi-automatic Rösler Z800 centrifugal cleaning system, while for drying the finished workpieces Ottobock chose the latest version of the RT550 Euro-DH rotary dryer, also supplied by Rösler.

Doncasters invests further in aerospace future

With post-Covid orders from commercial airlines higher than predicted, Doncasters is doubling the capacity of its US operations in Connecticut, and more than doubling production in shell lines at its UK site in Droitwich. This closely follows the announcement of Doncasters’ acquisition of Uni-Pol, which increased its annual revenue to over $500m. The two new robot shell lines at Doncasters Precision Castings – Deritend will be delivered by early 2023, more than doubling outputs and efficiencies. Doncasters is working with VA Technology to deliver the upgrades in the UK and US.
