Internal Grinders

Micron has a full line of small diameter internal grinders, also known as ID grinders. From multi work-head/multi spindle machines, to hydrostatic ways and linear motors, Micron has the ability to hold ultra tight tolerances on bores, angles, and faces. Our ID grinders are very popular for fuel injector grinding in the automotive industry.
