Central Machine & Marine

What Central Machine & Marine does

Central Machine & Marine Inc. (CMM) is a privately held industrial machining and fabrication company founded in 1973 in Sarnia, Ontario. The company operates a 70,000 sq. ft. manufacturing facility with equipment capable of handling projects up to 60 tons, organized across a two-shift, 18-hour daily operation staffed by 55 to 65 full-time workers. CMM provides four core service lines: precision machining and millwrighting, industrial repair and reverse engineering, TSSA-certified fabrication and welding (ASME Section VIII Div. 1, B31.1, B31.3), and on-site field services (shaft journal turning, line boring, gasket face resurfacing, bolt hole thread repair).

The company earns revenue exclusively through custom project-based quoting across multiple verticals: petro-chemical, marine (including Great Lakes shipping fleet support via Lake Huron dock access), power generation (renewable and traditional), mining and forestry, food and agriculture, and automation. Its competitive differentiation rests on a broad certification portfolio (ISO 9001:2015, TSSA, CWB, ASME, Lloyd's Register, National Board, CSA B51) and a credentialed workforce of certified welders, machinists, millwrights, fitters, engineering technologists, and trained inspectors. Pricing is quote-based with no published tiers, customers engage via website form, direct phone (24/7), or email, and the company is a partner of The Machining Group network alongside gfw.ca, thurstonmachine.com, and insitumachining.ca.

CMM is independently owned with no disclosed institutional investors, no funding rounds, no M&A activity, and no public listing. Distribution is direct-to-customer only, with no channel intermediaries. The operating geography is primarily North America, with marine services extending globally via Great Lakes Waterway access.
