Over 25 Years SealOver 25 Years of Passionate Part Making

We’ve been making turned parts for over 25 years. In 1990 Pioneer started with a few screw machines, centerless grinders and a young woman passionate about developing a machining business that delivers top-quality parts. From childhood, Aneesa Muthana had worked in her father’s bar grinding shop where she learned the business from bottom to top. While other girls got a Barbie for their birthday, she got a centerless grinder one year! At the ripe age of 20, her uncle purchased what would become Pioneer Service and three years later asked her to join as a partner. She said “yes”, but only on the condition that she become the president and run the company. This was only the beginning of tenacity that would not only launch Pioneer Service, but also give it staying power in the years to come.

Her uncle agreed, stepped back, and Aneesa poured her heart and soul into Pioneer Service’s success. The bar grinding experience was a natural launch pad for a business based on centerless grinding parts, which quickly evolved into making custom precision ground shafts on screw machines. Over the years Pioneer’s reputation as a quality manufacturer has grown, and in 2013, Aneesa launched the company into the CNC machining world, expanding the team and equipment capabilities.

Some milestones for the company include:

1995 – Moved to current location with 25,000 sq. ft. on Factory Road in Addison, IL
Focused on making precision ground shafts and parts grinding, both in-feed and thru-feed centerless grinding
2000 – Became ISO Certified for the first time
2013 – Added new CNC turning centers for production of parts up to 8.5” OD
2014 – Added new Swiss CNC Lathes for production of parts up to 0.79” (20 mm) OD
2015 – Added new Swiss CNC Lathes for production of parts up to 1.25” (32 mm) OD

Today Pioneer Service delivers quick turn-around times for prototype and production volume orders. We serve a vast number of industries including motion control, oil & gas, fasteners, HVAC, power tools, food processing and automotive. If it’s a turned part under 8″ OD, there’s a good chance that we can make it.

Our team takes pride in providing our customers with a competitive edge within their market by continually delivering the highest quality parts with reliable on-time delivery. We welcome customer, partners and friends to join us and experience the Pioneer difference. Turning parts to your print is our specialty.
