en.Wedoany.com Reported - Gerg has introduced the Wenzel LH Gantry 2617 coordinate measuring machine for precision measurement of large, highly complex structural components. The company, located in Hohenthann, Upper Bavaria, Germany, provides component manufacturing services for the automotive, motorsport, aerospace, mechanical engineering, and defense industries, working with materials including steel, aluminum, titanium, glass fiber, carbon fiber, and plastics.
Stefan Rocheanu, a measurement technician in Gerg's quality assurance department, explains that the components processed by the company range in weight from a few grams to several tons, requiring extremely high manufacturing precision. In the aerospace sector, parts must meet stringent customer acceptance criteria. These components feature complex geometries with tight tolerance ranges: maximum form deviation for large three-dimensional surfaces must be controlled to 0.02 mm, flatness for large planar areas is required to be below 0.02 mm, and positional tolerances reach 0.01 mm. Additionally, rotationally symmetric parts with depths exceeding 1000 mm must be measured, with coaxiality requirements as high as 0.04 mm.
Previously, Gerg had limited capability for measuring large components, relying on optical methods for in-house inspection or outsourcing contact measurements to external partners, a process that was time-consuming and costly. To address this issue, the company decided to procure a coordinate measuring machine, ultimately selecting the Wenzel LH Gantry 2617. This device offers a measuring range of 2600 × 6000 × 1750 mm, making it the largest model in Wenzel's series, specifically developed for high-reliability and high-precision inspection of large-volume, heavy components.
The measuring machine features an overall design optimized with full mechanical integration, using granite material for all axes to ensure rigidity, vibration damping, and long-term stability. Each axis is equipped with air bearings, and the Y-axis adopts a high-rail guide design, making the structure more stable and ensuring reliable measurement results even under dynamic motion conditions. The device can be optionally equipped with an active vibration damping system, eliminating the need for a separate foundation. Automatic temperature compensation and an optional rotary table further enhance the machine's flexibility.
Gerg ultimately chose the Wenzel measurement system based on multiple factors: the cost-effectiveness of the solution and its ability to seamlessly integrate with existing measurement software, ensuring smooth workflows. With the introduction of the LH Gantry 2617, the significantly extended Y-axis enables Gerg to precisely measure extra-long, large-volume workpieces, greatly expanding the machine's application range. Stefan Rocheanu emphasizes that these precision-manufactured components must undergo efficient and repeatable measurements, with measurement records provided to customers. The device performs measurements accurately, generating reliable and repeatable results to demonstrate process stability or, if necessary, to facilitate optimization.
