The D’Andrea Success Story: 70 Years of Innovation in Machine Tool Manufacturing

D’Andrea, a global leader in high-precision CNC tooling based in Italy, began with a manual facing head in 1951 and has grown into an industry leader in CNC machine tool accessories. What started as a small family-run business is now an internationally recognized manufacturer, exporting 70 percent of its products worldwide. The key to D’Andrea’s longevity and competitive advantage has been its embrace of continuous innovation. Their latest example? Digitalizing their operations using Siemens comprehensive software to run their end-to-end manufacturing processes with Siemens advanced CAD/CAM software.

As a trusted Siemens partner, ATS Global supported D’Andrea in modernizing its operations and helping D’Andrea boost efficiency, ensure product consistency, and stay competitive on a global scale — all while maintaining its commitment to quality and craftsmanship. Watch the full video to see how the family-owned company shares how they’ve reduced programming time by 50% and reduced production cycles from one week to just 48 hours using Siemens technology. Learn how D’Andrea transformed into a digital company, enabling them to innovate faster, boost efficiency in production, and successfully compete with much larger companies.

Legacy meets part manufacturing innovation

D’Andrea made its name early on by solving real manufacturing problems. Their first facing head allowed machinists to perform turning operations on a milling center — something no one had done before. This early innovation set the tone for a company culture centered on practical problem-solving and precision. But as customer expectations evolved, so did the complexity of manufacturing. D’Andrea faced the same challenges many traditional manufacturers face: disconnected workflows, long programming cycles, limited data access between teams, and increasing demand for faster turnaround. That’s where Siemens came in.

By adopting NX CAD/CAM software, D’Andrea connected every step of its production process — from initial design to final machining — within a unified digital ecosystem. Engineers model parts and assemblies in NX CAD and embed manufacturing data directly into the 3D model. This PMI (Product and Manufacturing Information) is then carried through to NX CAM, where it’s used to automate toolpath generation, simulate machining processes, and optimize operations before they hit the shop floor. This digital thread eliminates guesswork, minimizes rework, and ensures every team, from R&D to production, is working from a single source of truth.

Results that Matter: Faster, Smarter, Precise Part Manufacturing

The impact has been measurable:

• CAM programming time cut by 50%
• Production cycle time reduced from one week to just 48 hours
• Error rates minimized thanks to simulation and automation
• Improved collaboration across departments using real-time data
• More flexibility to handle high-mix, low-volume production

As Ihor Tymoschenko, CAM Programmer at D’Andrea, explains:

“NX CAM is a comprehensive system that doesn’t require extensive preparation. The ability to program both turning and milling in the same environment allows me to visualize all tools and operations seamlessly.”

Transforming tradition with digitalization

With Siemens Xcelerator software at the core of its operations, D’Andrea is able to match the speed, quality, and scale of much larger manufacturers, all while maintaining its family-owned agility and deep engineering expertise. Their story is a blueprint for small and midsize manufacturers looking to modernize, stay competitive, and unlock new levels of efficiency. D’Andrea’s journey shows what’s possible when tradition meets transformation. If you’re in manufacturing, engineering, or industrial innovation, this is one story you don’t want to miss.
