Micromachining Turns Images of the Queen into Tiny Portraits

Engineers at the University of Sheffield Advanced Manufacturing Research Center (AMRC) used a turn/mill center to reproduce a series of tiny portraits of Queen Elizabeth II, down to only 1.4 mm wide, onto brass.

Speed Matters in Microtooling Applications

A variety of tooling spindle options brings micromachining work within reach for shops looking to expand their capabilities.

Measuring the Merit of Ceramic Cutters

In testing new ceramic microtools, a precision dynamometer ensures that cutting forces are measured precisely so tool performance parameters can be determined.
