Ultra Machining Fab

Ultra Machining is what ARC calls projects that have some, if not all of the dimensions falling between the nano (sub-micron) and the macro (typical machined parts >0.0002 inches). ARC’s Ultra Machining Fabrication group offerings are show below. Due to its involvement in the semiconductor, medical and defense markets which require a blend of technologies to meet customer requirements, ARC has acquired a unique set of tools and developed processes to benefit our customers.

Shown below in ARC’s Micro Machining Gallery is a selection of the myriad of the most interesting devices completed.

Drawings and sketches may be submitted via our contact page you will be contacted shortly to discuss your project.
