On-Site Machining (OSM)

On-site Field Machining Services – Where You Need It, When You Need It…

In order for your plant to perform at optimum levels all the time, ongoing repairs are a part of doing business. But making these improvements or adjustments shouldn’t have to compromise operational efficiencies.

By utilizing the full range of Furmanite’s On-Site Field Machining (OSM) services, you receive work and results that exceed any standard of quality – ensuring plant productivity and longevity. But you’re also able to realize tremendous savings in transportation, logistics, labor, time, and – of course – money.

Furmanite introduced its On-Site Machining (OSM) service in 1979, which has since developed into a comprehensive site machining package complementing the full range of other Furmanite specialized services. Comprehensive ranges of machine tools have been developed and manufactured in-house that are able to meet the most demanding requirements found on clients’ sites.
