Precision CNC Machining you can count on
Complex parts and close tolerances, from prototype to production, engineered to ±0.0001″, all under one roof.

Our CNC machining services
Best Machine Inc. is a precision CNC machining company in Fremont, New Hampshire, delivering high-quality machined components to mechanical engineers, OEMs and procurement teams across the instrumentation, metal-sensor, medical-device and industrial sectors. Specializing in CNC Milling (CNC vertical milling, CNC horizontal milling, 5-axis machining and mill-turning), CNC Turning (CNC turning, mill-turning and Swiss turning), EDM (wire EDM and hole-drilling EDM) and laser marking, we produce complex, tight-tolerance parts with accuracy down to ±0.0001″.
Because we own our machines outright and keep overhead low, our experienced machinists and engineers turn demanding designs into precision parts, from prototypes and low-volume work to repeatable production runs, at honest, competitive pricing. ISO 9001:2015 certified and serving New England, Best Machine Inc. is a trusted CNC machining partner for instrumentation and sensor manufacturers.
Three generations of precision machining.
Milling is the heart of what we do, backed by CNC turning and Swiss machining. Because we own our machines and run lean, you get top-tier quality at honest, competitive pricing, built for production volumes.

Milling is what we do best.
Milling is the heart of our shop and our most precise work, from 3- and 4-axis to full 5-axis and mill-turn. We hold tight tolerances on instrumentation, sensor and medical-device components, and we’re built to repeat them reliably at production volume.
