Colburn Manufacturing was founded in 1999 by Scott Larson in a garage in Robbinsdale, MN. The original shop consisted of a manual lathe, a manual mill, and a Hardinge CNC lathe was added shortly after opening.

Colburn Manufacturing quickly outgrew its original space and in 2001 moved from Robbinsdale to Osseo, MN expanding to a space of 720 square feet. Continued growth soon required a move to a larger space of 3000 square feet. The Company added a Citizen Swiss machine (the first Swiss for the shop) as well as a Kitamura CNC Milling Center. Deltronic Optical Comparator was added to ensure quality control.

In 2004 Colburn expanded to a newly built building in Big Lake, MN. The company added 4 more Swiss machines were purchased, as was a Micro-Vu camera inspection system, 3 microscopes and 4 tumbling machines to further expand inspection and quality control. To aid in clean up and fluid conservation, the Company added a chip spinning oil recovery. In addition, the Company also added 3 different tool sharpening machines.

In 2014, Colburn purchased and relocated to a 15,000 sq. ft. building in Fridley. In 2015, Colburn added an additional three Swiss Machines.
