In 2021, cylindrical grinding machine manufacturer Grindex, based in northern Serbia, installed its first CMM, an Altera M 20.12.10 manufactured in the UK by LK Metrology. The ex-demo machine is in daily use checking tolerances mainly to below ±0.05 mm and sometimes half that value. When the company was looking to invest, a CMM was chosen in preference to an optical scanning metrology solution, which was not regarded as being sufficiently accurate, probably by a factor of 10.

Having a nominal inspection volume of 2000 x 1200 x 1000 mm, the CMM is installed in a dedicated inspection room in the user’s Kikinda factory. The machine was supplied with a touch-trigger probe for general inspection and complex stylus builds, and an analogue scanning probe for rapid capture of dimensional and surface data from castings, engine housings, machined components, moulded parts, fabrications, additively manufactured components and assemblies. Training and initial programming assistance formed part of the LK package, as well as ongoing consultancy.

The LK machine was selected in preference to alternative brands of CMM based on recommendations from other manufacturing companies. Notably, the equipment has considerably upgraded the metrology capability of Grindex, whose quality control toolbox was previously limited to a profile projector, micrometers, height gauges, callipers and a combined machine for roughness testing and checking the roundness of smaller parts.

With the CMM, more comprehensive and earlier detection of out-of-tolerance features provide the ability to spot errors in a metal-cutting program earlier, lowering costs both through more efficient production and a reduction in scrapped parts.

Nikola Biresev, quality manager at Grindex, says: “The LK CMM is used not only for quality control activities and problem-solving, but also to support R&D.”

Nikon Corporation has launched the VOXLS 20 C 225, the latest addition to its VOXLS X-ray CT product line up. This system is based on the established principles of the company’s VOXLS 30 and 40 series systems, offering maximum capability in a space-efficient footprint.

According to Nikon, the VOXLS 20 C 225 presents the largest CT scanning envelope in a system that fits through a standard double door, allowing for flexible integration to almost any quality control or production environments. It features Nikon’s metrology-grade platform with a granite base, rigid steel manipulator towers, and high-accuracy encoders and motors.

The machine offers an inspection volume of 555 mm (diameter) x 759 mm (H) in a compact footprint of 2451 mm (L) x 1173 mm (D). It features a motorised dual-source set up with a 225 kV reflection target and 160 kV transmission target, allowing users to choose the optimal source for their application at the push of a button. This enables automated and fast switchover between the reflection target (for higher productivity due to increased X-ray flux) and transmission target (for best possible resolution).

Source optimisation de-skills the process of setting up the filament for optimal performance, simplifies the filament change process, and provides longer filament lifetime.

For enhanced usability, the machine incorporates features like filter changer, a motorised door that opens in under 4 seconds, and a large viewing window for excellent interior visibility.

As a point of note, versatile scan capabilities support motorised FID and advanced scan modes, enabling a wide range of inspection techniques for diverse applications. The first Nikon VOXLS 20 C 225 systems are scheduled for delivery this autumn and will serve industries including additive manufacturing, aerospace, automotive and medical device.

Ametek Inc and Faro Technologies have entered into a definitive agreement under which Ametek will acquire all outstanding shares of Faro Technologies’ common stock for $44 per share in cash, which represents an approximate 40% premium to Faro’s closing price on 5 May 2025. The transaction values Faro at approximately $920m. The boards of directors of both companies have unanimously approved the transaction.

Founded in 1981 and headquartered in Lake Mary, Florida, Faro Technologies is a provider of 3D measurement and imaging solutions, including portable measurement arms, laser scanners and trackers, software solutions, and service offerings. Faro’s precision manufacturing and digital reality solutions serve a diverse range of end markets. The company has annual sales of approximately $340m.

“Faro is an outstanding acquisition for Ametek and an excellent strategic fit with our Ultra Precision Technologies division,” says David Zapico, Ametek chairman and CEO. “Faro’s differentiated 3D metrology and imaging solutions expand our presence in attractive growth markets. Its strong brand, global customer base, employees and technology capabilities complement our existing Creaform business and provide compelling opportunities for growth and margin expansion.”

Peter Lau, president, CEO and director of Faro Technologies adds: “With Ametek’s global scale, operational excellence and commitment to innovation, we’re well-positioned to accelerate our growth and continue delivering cutting-edge solutions to customers around the world.”

The transaction is subject to customary closing conditions, including applicable regulatory approvals. It is also subject to the approval of shareholders in Faro Technologies. The transaction is expected to complete in the second half of 2025.

At the annual Control 2025 exhibition in Stuttgart, Germany earlier this month, Italy-based ViciVision showcased the potential to combine confocal and touch probes in a single machine with its new Techno 914 series. This combination allows for dual non-contact and tactile measurement capabilities to meet a wide range of complex measurement demands.

The confocal system can perform fast, accurate, non-contact measurements of complex surfaces and hard-to-reach areas for splined shafts, while the touch probe supports shaped-defect measurements needs such as axial run-out, flatness, perpendicularity and keyway dimensions.

According to ViciVision, the result for users is efficiency, precision and seamless integration by providing multiple measurement modes within a single device. In turn, this enhanced efficiency and reliability optimises production workflows.

Through the strong combination of non-contact and contact measurement technologies, ViciVision says its Techno 914 series “redefines the possibilities of precision measurement”. Its multifunctional design not only enhances production efficiency but also significantly optimises quality control processes, making it an indispensable tool in modern industrial environments striving for excellence.

Notably, the machine is designed for use directly on the shop floor, allowing for immediate inspection and feedback on the production line. By enabling on-site measurements, the Techno 914 reduces downtime, eliminates bottlenecks and helps operators make adjustments before parts go out of tolerance, leading to fewer rejects. 

ViciVision’s Techno 914 is well-suited to measuring a variety of turned parts, including those used in the automotive, aerospace and medical industries. The machine features an ergonomic workpiece clamping lever for easy handling and a large open front for convenient loading and unloading.
