The requirements for precision and efficiency are becoming increasingly specific. For this reason,Wenzel is expanding the standard sizes of its small CMMs in the LH series. With the introduction of the new sizes LH 67, 85, 105 and 107, the company now offers a wider range of machine variants that cover different measuring ranges. In turn, the expansion enables Wenzel to respond even more specifically to the individual needs of customers.

Wenzel has not only expanded the range of variants that make up its small LH machines, but also significantly increased the productivity and dynamics of these CMMs. From the smallest size, the LH 65, it is now possible to integrate the Revofive-axis measuring system from Renishaw. Revo offers a fast and accurate measuring process that improves measuring throughput and even includes the option of roughness measurement.

Notably, Wenzel attaches great importance to sustainability. The new LH machines feature a design that minimisespower and air consumption. With an environmentally friendly concept that focuses on durability and minimal wear and tear, Wenzel says the LH series actively contributes to lower CO2 footprint. This environmentally conscious approach ensures that the machines are not only efficient, but also sustainable.

With the expansion of the LH series, the companysays it is taking a significant step towards the future. With precise, economical and environmentally friendly solutions, Wenzel’s aim is to continue offering advanced machines and providing customers with the best solutions for their individual needs.

When it comes to carbide tools, there are always products that push the boundaries of what was previously considered technically possible. Some of these products are made by Zecha Hartmetall-Werkzeugfabrikation GmbH,like a two-flute end mill with a diameter of 10 µm or a PCD tool that has 42 cutting edges with a diameter of 6 mm. This leads to the question of how to measure such small tools, which are many times smaller than a human hair, and how to ensure that the machining process is reproducible.

“It’s especially important that measurement takes place in the machine, because this is the only way to record and compensate for all influencing factors,” says Marcus Becker, milling application engineer at Zecha.

Since machine manufacturer Kern has been integrating laser measuring systems from Blum into its precision machines for many years and Zecha has its own high-end machine, it did not take long to decide on the LC50-DigiLog

In contrast to conventional laser systems that generate a single measured value when the laser beam is shaded to a certain degree, Blum says that the LC50-DigiLog laser measuring system determines the actual measured value based on thousands of individual values per second. In addition, thanks to the large number of measured values per cutting edge, the system detects contamination and cooling lubricant deposits on the tool and calculates them out of the result.

Unsurprisingly, in addition to tool measurement, tool breakage detection is also an important issue with micro-tools. This is where non-contact measurement at high machining speeds, made possible with the DigiLog system, offers great advantages.

Zecha also uses LC-Vision software from Blum-Novotest: measuring and visualisation software that generates, visualises and evaluates a variety of measurement applications on the control screen.

Hexagon’s Manufacturing Intelligence division has a new technology to reduce quality inspection delays in large-scale manufacturing operations. Combining laser tracking with laser radar functionality, it enables manufacturers to measure detailed features and meet tight assembly tolerances from tens of metres away. Built on established measurement and positioning technology, the new Leica Absolute Tracker ATS800 offers significant productivity improvements in large-scale part manufacturing and assembly operations by safely and rapidly measuring critical features.

The new system enables manufacturers to measure fine edges and features across large volumes productivity from a convenient stand-off distance. Whether inspecting large aerospace or automotive structures, ship sections, or wind turbine components, there is no need for operators or robots to be in close proximity to the part. This capability avoids unreliable measurements and safety issues,while also providing significant time savings. 

By combining direct scanning and reflector tracking capabilities, the system replaces two pieces of hardware with a single device. Using Hexagon’s patented PowerLock technology, the ATS800 automatically and immediately ‘locks on’ to a fixed reflector and tracks its movements in real time, providing an absolute position reference. The ability to measure target reflectors also greatly simplifies robotic automation processes, providing precise position referencing within a wider co-ordinate system when the tracker is mounted on a linear rail or an autonomous mobile robot (AMR). 

It is possible to measure an aircraft fuselage, for example, quickly and without bringing target reflectors to the part, reducing total inspection time from hours to minutes. Using multiple devices or an AMR, several fuselage sections or panels can undergo batch inspection overnight, further reducing inspection time and avoiding disruption during shifts.

Nikon Metrology has welcomed the recent update to Volume 5.1 of the automotive measurement standards issued by the German Association of the Automotive Industry (VDA). The newly updated VDA standards cover a more comprehensive array of measurement applications within the automotive sector, addressing the industry’s growing demand for more diverse and sophisticated metrology solutions.

“We already offer innovative, traceable measurement solutions based on national and international standards for the automotive industry,” explains Andreas Fuchs, application engineer at Nikon Metrology. “The new standard defines very clearly the procedures for evaluating the precise technology that we provide. After all, with the APDIS laser radar, our portfolio has featured a product for some time now that can also deliver traceable inline measurements as described in VDA Volume 5.1. Incidentally, those who use this technology no longer need a dedicated measuring room for a fixed CMM, enabling them to save a great deal of money, time and space.”

The APDIS laser radar measures details at a distance without needing handheld probes, targets or surface preparation, making it suitable for automating repetitive inspection tasks with high accuracy. The system covers many manufacturing, industrial and research applications, including those that involve hard-to-reach features and are complex, delicate or labour-intensive.

Additional benefits include fast and accurate automated measurements with minimal set-up time for high productivity with flexible and portable installation. This capability allows for the absolute and accurate measurement of parts during production or wherever required, including directly on the production line. In particular, Nikon Metrology says the APDIS laser radar displays its strengths in the automotive industry. For example, the system can measure automotive features with absolute accuracy at high speed with no part preparation, whether inline or offline.
