Unparalleled Precision CNC Machining

Decades of experience and cutting-edge equipment combine to deliver multi-axis CNC and wire EDM-machined components you can rely on.

Performance, Accuracy, Repeatability

Control manufacturing and production risks for performance-critical components. Precision CNC machining delivers parts that meet exact specifications, behave predictably in real-world conditions, and remain consistent from prototype through production.

Precision CNC machining from Greene Group Industries enables you to:

Achieve exact tolerances, increasing your confidence that critical dimensions are met precisely

Protect downstream assembly and system performance with assurance that the first part and the thousandth part perform the same

Reduce late-stage surprises by relying on proven machining processes and tight process control

Move from prototype to full production while maintaining precision and quality

Achieve tight tolerances at scale with reliable repeatability.

Engineering Greater Value, from Concept to Production

Decades of experience serving some of the world’s most influential OEMs have informed our integrated approach to precision CNC machining. Bolstered by today’s most advanced equipment and technologies, we identify areas to increase certainty and control costs for our customers.

Commitment to Investing in Top-tier Equipment

We continue to invest in our facilities and equipment to enhance our service. Recent purchases include state-of-the-art 13-axis milling and turning centers, enabling us to complete highly complex designs in a single setup without secondary handling or finishing. This saves our customers time and money while delivering the highest-quality product.

Our CNC department consists of over 60 machines, including:
  • CNC mills – 4 and 5 axis – Brands: Willemin, Brother, Makino, Haas, Mori
  • CNC lathes – Brands: Mori, Takizawa, Haas
  • Wire EDM machines – Brands: Fanuc
  • Multi-axis mill/turn centers – Brands: Citizen, Traub, Mori
  • CNC grinding
  • Conventional machining

Micro-machining with repeatable precision

Manufacturing micro components requires specialized expertise in tooling and material response at the ultra-small scale. We have decades of experience micro-machining parts for critical applications in the medical, aerospace, electronics, and communications industries with rigid performance requirements.

What Our Customers Say

“GGI has been a 5-star partner for us. After working with GGI through several projects over 6 years, I have found them to be incredibly responsive, and they have provided us with unparalleled quality on some of the most challenging MIM components. GGI has consistently developed novel ways to design their tooling to meet our demanding specifications on the latest surgical technology.”

Sr. Manufacturing Engineer,

Large Medical Device OEM

“GGI has remained a top-tier supplier long term. The highest levels of responsiveness and professionalism set them apart in support of rapidly changing requirements and extremely dynamic end customer requirements. Much of our success ties directly into these very high levels of support. Continuing thanks to GGI for all the support over all these years.”

Purchasing Manager,

Leading Equipment and Systems Manufacturer

“I wanted also to share that if I am ever asked to rank all of the vendors I have worked with according to responsiveness, achieving goals, communication, skill, and overall medical product knowledge, GGI wins, hands down. It is a pleasure seeing the project turn into a trusted process. Thanks to you both and your team!!!!”

Design Assurance Engineer,

Large Medical Device OEM

“Over the past several years GGI has worked with my project team to develop components for multiple innovative new devices. The complex nature of our designs makes these projects challenging and require a lot of personal attention, crisp communication, and creative problem-solving to meet our project targets of timing, cost, and superior quality. GGI has demonstrated their willingness and ability to deliver in these areas, making them a valued partner for our business.”

Director of Advanced Instruments

Large Medical Device OEM

“GGI’s project management support is the best of any MIM house we have worked with. We are confident when placing a new tooling PO with GGI that we are going to close the project on time. When we get into production, GGI partners with us to continually improve the process and cost over time. We ask GGI to help us compete and they are always there looking for new ways help us to advance.”

Sr. Buyer

Large Medical Device OEM

“GGI rapidly develops complex machined components and assemblies with the highest possible quality. They take on our most challenging parts right from the prototyping stages, support all development efforts and carry them through to production seamlessly. They support our development efforts as if they are part of the internal team and their level of communication is superb.

GGI has been essential to product success and bringing the highest possible quality devices to the customer. They take on real challenges and work to solve them, not only with highly precise machined parts but with a range of processes and capabilities.”
