The 35th Control International Trade Fair for Quality Assurance included 589 exhibitors from 32 countries presenting cutting-edge technologies from the fields of vision technology, image processing and sensor technology, as well as measuring and test technology. The event brought together suppliers with users, exhibitors with expert visitors, and manufacturers with customers and partners.

Machine manufacturer Klingelnberg presented its portfolio of products and services, including the Klingelnberg Precision Measuring Center P 152 for mid-sized gears, as well as the Klingelnberg Precision Measuring Centers P 26 and P 40 with optical metrology and tried-and-tested universality of application in metrology.

“As a leading trade fair, Control was a complete success for us again this year,” said Dr. Kai Bartel, head of measuring technology at Klingelnberg.

When the first generation of the Klingelnberg Precision Measuring Center P 26 was developed 25 years ago, it was impossible to foresee how much this development would ultimately shape Klingelnberg’s metrology offering.

“The P 26 precision measuring center in particular has become a fixture on the shop floor,” said Bartel, director of product line, Precision Measuring Centers. “And we’re extremely proud that we have been able to integrate not only new measuring strategies, but also temperature compensation for hybrid metrology. We now have a clear line of sight to achieving even greater reductions in measuring time in the shop-floor environment.”

P 40 is a universal all-rounder for reducing measuring times in series measurement thanks to the hybrid solution. Measuring times have been significantly reduced through the introduction of hybrid metrology with optical pitch measurement. It is now possible to perform optical pitch measurement on almost all surfaces using the white light sensor technology (HISPEED OPTOSCAN) developed by Klingelnberg and partners, along with other innovative measuring strategies. Two other processes for reliably measuring single pitch deviations are also available.

“With the current release, the pitch, tooth thickness, and radial run-out of gears can be measured optically on most cylindrical gears,” said Holger Haybach, head of product management, Precision Measuring Centers. “So, depending on the number of teeth, this reduces the measuring time for a complete gear measurement by up to 40 percent. For pitch measurement, even greater time savings are achieved on a consistent basis.”

All Klingelnberg Precision Measuring Centers in the P 26 to P 65 series can be optionally retrofitted with the optical sensor (HISPEED OPTOSCAN). For new machines, the “Ready for Optic” option is also available, providing a factory-installed setup for subsequent retrofitting.

The increasing cost pressure on large components for wind power requires new technologies that will enable proven principles for high-volume and mass production of smaller components to be transferred over to large components. The newly developed Klingelnberg Precision Measuring Center P 152 closes the gap in the portfolio between the mid-sized and the large precision measuring center model series.

The latest addition to the series is capable of measuring components with a maximum outside diameter of 1,520 mm and workpiece weights up to 8,000 kg with the usual measurement precision. Klingelnberg has succeeded in scaling the technology concept of the small and mid-sized series to the larger component dimensions. The inherently rigid machine bed with its 3-point support plays a key role here. The 3-point support enables the integration of an active vibration platform into the machine bed. This means that even the low-frequency oscillations from the shop floor can be safely absorbed without the use of a vibration-isolating foundation. Consequently, all changes visible in the measurement results can actually be attributed to the component.

The P 152 for mid-sized gears such as planet gears used in wind power combines dimension, form, and position measurements with gear measurement, making the operating principles used in high-volume and mass production applicable to large gears as well. Form measurements, such as roundness and cylindricity measurements on machine elements, are becoming increasingly important. Special measurements and evaluations on gears with a bearing function have therefore been developed, and are also available for the P 152. And the P 152 also offers all the possibilities of the “Done-in-One” principle in its diameter range.
