Over 30 Years of Part Making

Our Story

In 1990 Pioneer Service started with a few Brown and Sharp screw machines and Centerless grinders, and a team intent on developing a precision machining business that delivers top quality turned parts.

Over 30 years later, that mission is our purpose and vision.

Pioneer Service continues to deliver quick turn-around times for prototype and production volume orders of precision CNC turned, Swiss machined parts and centerless grinding services. We serve a vast number of industries including: Medical, Aerospace, Electric Vehicles, Hydraulics, Motion Control, Oil & Gas, Sporting Goods, Food Equipment, Lawn and Garden and many others.

Our team takes pride in building long term relationships with our clients by continually supplying them the highest quality parts with reliable, on-time delivery.
