Small Hole EDM

The K3HS is a high speed small hole driller EDM machine that drills difficult to cut carbide and heat treated workpieces. The K3HN is often used as a production machine to EDM start holes in die plates and is sometimes combined with an auxiliary axis to index or rotate a workpiece.

Product Descriptions

Since the K3HN hole popper is equipped with K-SMC, Sodick Motion Controller, the optimized servo control is activated and improves cutting speed by up to 200%.

Accurate fine feeding is controlled for stable machining.

The K Series features energy-saving designs and technologies. Compared to conventional Hole Drillers, the K3HN can reduce average energy consumption by up to 60%.

An automatic programming system, LN Assist, is standard on the K3HN. Its simplified graphics screen allows for easy operation. As LN assist is also capable of a series of calculations and macro functions, operators can easily work with any kind of complex cutting layouts and programs not dependent on their skills. A customized function is available where operators can register their own programs as a utility.

Standard on the K3HS, Sodick’s automatic electrode feeder enables continuous cutting with multiple electrodes for unattended machining. The Sodick AEF is capable of handling electrodes between 0.02” and 0.12” in diameter, with variable capacity, up to 40 electrodes at ø0.02”
