Zero Errors & Improved Productivity With Multi Sensor CMM

UK spring ring manufacturer Cirteq says it can now guarantee 100 per cent accuracy on each and every part it manufactures due to an investment in a world-leading quality control system. Cirteq currently makes around 700 million circlips and retaining rings annually, exporting them across the globe to more than 500 customers who use them in engine assemblies.

To ensure that its 3,800 product variants meet exacting demands for assembly, the company – part of the Titgemeyer Group – works directly with some of the biggest names across the global aerospace, automotive, rail and sustainable energy sectors, including Jaguar Land Rover, Volvo, Bosch, Siemens and Mitsubishi.

To help meet the strict safety criteria and incredibly high expectations of its customers, Cirteq identified the need for measurement technology innovation and discovered OGP UK, a specialist in multi-sensor metrology. OGP’s automated systems utilize a combination of world-leading optical, laser and tactile sensors, eliminating the need for multiple specialized measuring systems and collecting highly accurate data even on the most complex components and features, with speed and reliability.

Cirteq Customer Quality Liaison Manager Theo Speller has a clear message for other businesses making precision components. “I’d say that it’s time to take the plunge and get invested in vision systems, because you need to match your inspection methods with the inspection methods of your end users,” he said. “We went out into the market to look for a machine that could do everything that we needed – it needed to do 3D contact probing and also capture part 2D features.

“The machine that we found through OGP was the ZIP LITE 300. It has a 300mm table and can capture most of our products in the factory, with the Renishaw probing capability to help us build 3D models and capture every dimension our customers require.”

OGP systems work to sub-micron precision, making them right at home in an era of miniaturization where new material developments and ever-tighter tolerances have made components increasingly challenging to manufacture.

By making more accurate data available to production engineers in real time, OGP solutions empower them to identify and rectify quality control flaws on the spot, leading to less scrap, fewer production bottlenecks and higher productivity.

Mr Speller said: “If you go to a robot line you’ll see a camera over the top of it photographing every component and sub-assembly to make sure that it meets all requirements. We have to match that by making sure that our components are right 100 per cent of the time. Our expectations are to drive towards zero PPM.”

“We were not getting the repeatability that we needed from manual measurements due to operator bias. That’s the main advantage of this OGP machine – we’ve improved the quality and the accuracy of the measurements and the bonus is we’ve actually managed to do it and save time.”

“The cycle time that it takes to inspect has been slashed. We have to demonstrate the repeatability of the equipment that we use to the automotive customers and with the OGP machine we get that repeatability. In the last year we haven’t seen any measurement errors as a result and we’ve seen that initial spend came back in the first year because we’ve saved production time.”
