High-speed hole EDM by Sodick

Sodick's K-series range of machines can produce very small holes quickly and efficiently.

NC-device equipped high-end model, K3HN is advantageous in cutting multiple initial holes for wire EDM or in automated parts machining.

As an option, the K3HN can be equipped with a additional rotary and/or indexing axes making it the ideal product for Aerospace and Medical applications.
