Precision CNC Machining Services

Westfield Machine, Inc., specializes in precision CNC machining services, serving customers in the gas turbine and oilfield industries since 1982. We’re a family owned, customer centric operation, with a hands on approach; this ensures that when you call, your inquiries and concerns will be addressed by the people who have a vested interest in your needs. This approach, combined with a wide array of machining capabilities, position us as a single source turnkey solution from design to finishing.

Our state-of-the-art facility is equipped with advanced 5-axis CNC machining capabilities that allow us to achieve tolerances up to ±.005”. Geared towards heavy industry, we can accommodate the machining of large scale components such as boring up to 7’, turning up to 50” in diameter and 160” in length, milling up to 84” in length, 54” in diameter, with a lifting capacity of up to 15,000 tons

From gear hobbing to gun drilling and broaching, we can provide virtually any machining operation on materials such as carbon, stainless, and alloy steel, aluminum, nickel, exotic metals, and plastics. In addition, we also provide heat-treating; welding by AWS certified welders, various coatings, and non-destructive testing.

Regardless of operation, all work is done in-house, and in compliance with all major industry standards including: API 8C, ISO, ASTM, AWS, and any applicable Mil-Spec. To learn more about Westfield Machine, Inc. turn-key solutions, please see the table below or feel free to contact us directly.
