CNC Machining Services

Fathom offers CNC Machining services for the manufacture of precision plastic or metal parts. Utilizing high-speed CNC machines and the latest software programming, Fathom can produce complex pieces directly from 3D CAD data with detail-oriented precision using 3-axis, 4-axis and 5-axis CNC machines, including vertical milling machines, horizontal milling machines and lathes.

From rapid prototypes—both cosmetic and functional—to low-volume production parts, Fathom’s CNC machining team is part of its secure facility and follows processes to protect a company’s IP (e.g., NIST 800-53 Compliant). Companies trust Fathom with CNC machining projects that are time-sensitive, short production run related, involve high-complexity and/or require high-precision.
