Custom CNC Turning & Milling Services of Metal & Plastic Parts

Gem Manufacturing provides precision CNC turning and milling services in our state of the art facility in Waterbury, Connecticut. Delivering fast, two to four week turnaround on prototype to low-volume production of both plastic and metal components.

Experienced at machining many materials, including aluminum, titanium, acrylic, and nylon, we can produce parts as large as 40" x 20" x 17.7" with diameters up to 14.57". Milling operations are also equipped to handle parts weighing up to 1,500 lbs.

Widely used by the aerospace and medical industries, our CNC turning and milling services are capable of accuracies within ± .0005". Quality is important to us, and our ISO 9001 accreditation confirms our commitment to delivering the best results possible. We also provide many secondary services, such as plating, anodizing, and heat-treating for start-to-finish part production. Contact us today to learn more.
