CNC MACHINING


 

FATHOM’s team of CNC machining and turning experts deliver high-quality parts by way of modern machining methods while utilizing additive technologies to drive greater results. This hybrid approach is supported by highly skilled machinists and a diverse set-up of industry-leading equipment to accommodate many types of applications at any given time. Companies trust FATHOM with CNC machining projects that are time sensitive, short production run related, involve high-complexity and/or require high-precision.

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). Customers can choose from a wide variety of metal and plastic material options, or can make special material requests. The team offers a tolerance accuracy range from +/-0.001″ to 0.005″ and can support even faster lead-times for on-demand reorders.
