Automated CNC Machining Procurement for Radiography Instrument Manufacturing

GNR S.r.l. designs and manufactures advanced analytical instruments, including X-ray diffractometers (XRD), X-ray fluorescence spectrometers (XRF), and optical emission spectrometers (OES). Operating in Italy for over 40 years, the company develops systems requiring high precision, reliability, and repeatability for industrial radiography applications.

The production of these metrology systems demands machined components that integrate into calibrated assemblies. Minor tolerance deviations directly affect instrument reliability and measurement performance. Historically, GNR relied on a procurement workflow requiring 2D drawings and multi-step communications with external suppliers. This manual process extended lead times and restricted cost visibility during the engineering phase.

Accelerating the Design-to-Production Cycle
GNR required a method to optimize its procurement supply chain. The primary improvement goals were to accelerate component quotation, simplify internal design validation, and establish direct cost predictability without compromising the dimensional accuracy of the analytical instruments.

To address these operational bottlenecks, GNR implemented an automated on-demand manufacturing platform capable of processing 3D STEP models directly. This model-based approach bypassed the dependency on 2D drafts. The system provides immediate manufacturability analysis, pricing, and delivery schedules for CNC machining, specifically milling and turning operations. GNR selected this digital procurement infrastructure because it accommodates required surface treatments—such as anodizing, electroless nickel plating, and laser marking—within a single order interface, ensuring components arrive ready for immediate assembly.

Operational Results and Cost Optimization
The integration of this platform enabled a proactive design-to-cost methodology. Engineering personnel utilize the tool to link computer-aided design iterations directly with manufacturing evaluation and purchasing decisions. Measurable results include an approximate 50 percent cost reduction on complex geometries compared to traditional sourcing.

During the manufacturing of an arc-shaped diffractometer component, which local suppliers considered difficult to produce, the automated platform processed the geometry and supplied the part at half the historical cost. Quotation lead times shifted from a supplier-dependent delay to an immediate output upon 3D model upload. Furthermore, repeat orders are processed directly from a digital archive without additional technical clarification.

"Our objective was to create a smoother connection between design and production, with immediate visibility into costs and delivery times," stated Ali Cheayto, Sales Manager France at MISUMI.

Michael Manfredi, Mechanical Design Engineer at GNR, added, "Quotations are generated much faster than when working through a third-party supplier. We can upload the 3D model and instantly compare delivery times and pricing based on quantity, enabling us to make informed decisions quickly."
