Summary

The Makino EDAC1 is a sinker electrical discharge machine (EDM) engineered for ultra-precision machining of small electronic and micromachining parts. It enables production of extremely fine features, with inside corner radii as small as 5 microns and surface finishes down to 1.3µin Ra. The platform includes features such as ±1 micron depth control, stationary worktable, three-sided rise-and-fall work tank, and advanced motion control systems tailored for high accuracy.
