Renowned globally for its RONDCOM profile measuring instruments, Accretech has launched the advanced RONDCOM NEX series. The latest evolution of the instrument now features the provision of an axis speed potentiometer, as well as an auto force detector, making all measuring routines more efficient.

According to Accretech, RONDCOM NEX provides the best concentricity and straightness precision figures in its class: (0.02+3.2H/10000) µm and 0.15 µm (Z300) respectively. These advantages are made possible by the high rotational accuracy of the air-bearing based rotary tables. RONDCOM NEX R instruments also enable accurate surface roughness measurements, as per DIN EN ISO, in linear R and X directions, as well as in rotational directions on workpiece circumferences.

The flexible RONDCOM NEX series benefits from a modular design that enables the precision measurement of form, diameter and surface simultaneously. This modularity means that the instruments are available in a range of variants, ensuring that customers can specify a system that meets their own individual requirements. Also, Accretech’s ‘building-block’ approach means that RONDCOM NEX series instruments remain futureproof. For example, in addition to undertaking today’s precision measuring tasks, if the user’s requirements change, it is possible to retrofit new modules that suit developing needs. Similarly, new Accretech instruments can be purchased as manual systems, then later converted to CNC versions if a higher degree of automation is required. CNC add-ons include positioning tables with several asymmetrical measuring positions to accommodate complex workpieces.

“In contrast to stand-alone instruments, customers no longer have to compromise on accuracy when measuring form, diameter and surface parameters,” says Marcus Czabon, COO at Accretech. “We’ve fundamentally redesigned the entire series of form measuring instruments to ensure that our customers receive even greater support in terms of efficiency, time savings and automation.”

The Dudley factory of The Timken Company supplies the engineered bearings it manufactures into a multitude of industries, including mining, food and beverage, pulp and paper, cement, marine, and wastewater. However, recently there has been a significant increase in demand for larger bearings up to 1200 mm diameter for use in the construction of wind turbines, which promises exponential growth in the coming years as countries across the globe work towards meeting their green energy targets.

In May 2021, to enable the inspection of these larger bearings, Timken purchased an LK AlteraM 15.12.10 ceramic bridge CMM with axis travels of 1500 x 1200 x 1000 mm. Assisting further in the company’s quality control department is a Mitutoyo CMM capable of measuring ball and roller bearings with bores up to 800 mm in diameter. At the same time, LK upgraded this machine with a new controller and identical CAMIO 2021 software for measurement, programming, analysis and reporting so that inspectors are able to swap programs conveniently between both machines.

It is necessary to check dozens of high-precision geometrical features on each bearing to ensure that flatness, circularity, radial run-out and track width meet specified tolerances, some of which are within ±6 µm. Timken achieves this quickly, repeatably and automatically on the CMMs in computer-controlled cycle times of around 10 minutes.

William Hayes, quality improvement engineer at the Dudley factory, says: “We selected LK Metrology to provide the new inspection facility as it was the only potential supplier to offer us a new, well-priced, high-accuracy machine of the right capacity. The company was also proactive in offering to retrofit our Mitutoyo BN710 CMM with new control software, as we need two measuring machines to cope with our increasing production throughput.

Metrology specialist Wenzel presented its new GT series gear measuring machine live in public for the first time at last month’s EMO 2021 exhibition in Milan. The GT series is based on the company’s successful tradition in the development and production of specialised gear measuring equipment.

During the development process Wenzel says it improved many decisive details. For instance, the new GT series works with the company’s standard WPC control and comes with a completely new gear measuring software – WM Gear, which was developed by Wenzel and includes the universal WM Quartis measuring software. With the GT series, Wenzel says it is setting standards as gear measuring technology grows together with universal measuring technology: tactile and optical.

The GT series provides solutions for a wide range of measuring tasks involving small-modulus gears and rotationally symmetrical components. It can measure parts that extend from toothed workpieces and shafts used, for example, in commercial vehicles, railway transmissions, or construction and agricultural machinery, through to the measurement of marine gears.

For the easy clamping of shafts, the gear measuring device can be optionally equipped with a counter holder. Using the counter holder, it is possible to measure diameters of up to 1200 mm. For components where measurement does not require a counter holder, users of the machine can measure diameters of up to 1600 mm.

With the new GT series of gear measuring machines, Wenzel is thus supporting a wide variety of industries, providing solutions for the automotive and energy sectors, as well as materials handling, agriculture, the aerospace industry, and mechanical and plant engineering.
