JSEDM specialises in machining hard and complex electrically conductive materials through controlled electrical discharge. Its wire-cut EDM machines use a continuously moving electrode wire to produce precision profiles, punches, dies, gears and complex components. Its CNC and ZNC die-sinker machines use shaped copper or graphite electrodes to manufacture cavities, deep features, narrow slots and complex mould geometries.

A key capability of JSEDM is the development of its own control systems. The company manages the process from system design and component selection to trial production, machine validation and continuous improvement based on customer feedback. The objective is to provide stable machining performance, simplified operation, high cutting efficiency and lower maintenance costs.

Its equipment range covers submerged and flushing-type wire EDM machines, table-type and moving-column CNC EDM machines, twin-head systems and economical ZNC machines. Configurations can be customised according to workpiece dimensions, weight, required accuracy, production volume and process requirements.

JSEDM has also expanded beyond conventional EDM equipment into diamond-wire cutting technology. Its diamond-wire systems target SiC, semiconductor and advanced optical-material applications, where manufacturers require precise cutting with controlled material loss and surface damage.

By combining EDM experience, proprietary controls, precision motion technology and customised engineering, JSEDM provides complete machining solutions rather than standalone machines. Its value is to help manufacturers process difficult materials, improve accuracy, shorten production time and maintain reliable long-term operation.
