Greater Precision for Continuous Improvement: Atlas Pressed Metals acquires Sodick AD55L Sinker EDM


Electrical Discharge Machine (EDM) is a machining method primarily used for hard metals or those that would be impossible to machine with traditional machine tools. A Sinker EDM is especially well-suited for cutting intricate contours or delicate cavities that would be difficult to produce with a grinder, an end mill or other cutting tools. Atlas currently does most all repairs to tooling in house, the Sinker EDM is an integral part of our tool repair and replacement program.

Atlas upgraded to a brand new Sodick AD55L Rigid Linear Motor Driven Sinker EDM for higher precision, and the ability to produce finer, more intricate details on powder metal compaction tooling; to accommodate larger tools for higher compaction tonnage presses. With a maximum workpiece weight of over 2200 pounds, and capability to accept a punch over 22 inches in length, this EDM should cover most any Powdered Metal (PM) tool in the entire industry; and to produce much finer finishes and reduce EDM time. With less labor-intensive hand polishing required we will achieve quicker lead times, shorter press down time, and reduced labor to improve the overall cost of our final products.


"It is very exciting to have this level of technology for tool and die work here at Atlas. Investing in an EDM of this caliber really shows that we are committed to supporting our customers and being the best at what we do,” says Dan Dixon, Atlas Tool Shop and Machining Manager.
