Oil Wire EDM


Meeting the growing demands for improve surface finish and shape accuracy of precision metal stamping die. Under standard machining condition, the UPV machines deliver a surface finish of Rz0.2µm.



The unified Hyperi control delivers an identical streamlined interface to both Wire and Sinker EDM operations, and provides new levels of capability, efficiency, and user friendliness. New Generation – Touch screen controller available for both Sinker and Wire EDM that makes machining easy as Ready, Set , Go! Some functions include:

E-Tech Doctor

E-Tech Doctor can help you achieve your perfect part! E-Tech Doctor is a revolutionary method of adjusting machining conditions to create the desirable result.

EDM Assist Functions


All machine manuals reside electronically within the Hyper i control , and are organized with index and search functions for quick access.


On-board training system with integrated video provides a convenient training and reference tool.

Consumables Tracking

Monitor and track machine consumables and maintenance intervals.


Shape accuracy: ±0.5µm (actual measured Value)

Wire feed delay and material removal are automatically controlled to machine precise shapes and corners with exacting accuracy. Excellent shape accuracy maintains uniform clearance between the die and punch, thereby extending die service life.

Outstanding performance

The UPV machine are built to deliver outstanding performance, thanks to their optimum axis layout, highly rigid construction and the rigorous inspections conducted in every assembly process.
