Ultra precision discharge processing

1/1000 mm, micron order parts machining with ultra-precision electric discharge machine

Advances in the development of ultra-fine electric discharge machines have made it possible to develop ultra-fine parts machining, which is especially required for micromachines. The field of parts manufacturing is now shifting to a world where it is possible for the first time with a system that integrates electronic, chemical, and mechanical engineering technologies in addition to conventional technologies.

Achieves a minimum hole diameter of 5 microns

Ultra-fine machining with a minimum hole diameter of 5 µm and a surface roughness of Rmax of 0.1 µm has been achieved under the best machining conditions by developing a highly accurate tool electrode mechanism and minute energy discharge.

​Next-generation processing technology


AB Coating

AB coating (discharge surface treatment) is a new surface treatment technology that forms a surface of a ceramic or conductive ceramic on the surface of the material to be treated by repeating minute pulse discharges. TA (titanium alloy) and SA (silicon alloy) can be coated with high durability, wear resistance, and corrosion resistance. Process to such high inner cylindrical surface adhesion to form a surface modified layer which is melted and the substrate unlike the conventional coating be possible.

Electric discharge surface treatment is a new surface treatment technology that forms a metal or conductive ceramic film on the surface of the material to be treated by repeating minute pulse discharges. Using an electrode composed of powder material (TA electrode or SA electrode), processing is performed in electric discharge machining oil that is generally used in electric discharge machining.

A pulsed discharge of minute energy is generated between this electrode material and the material to be treated, and the energy causes the melted electrode material to move to the melted part on the material to be treated, forming a film. ..

Although the temperature is locally high enough to melt the material, the processing proceeds at room temperature as a whole. Therefore, the material to be treated can be treated without being deformed or cracked by heat.

Application example: TA film treatment on punching blade mold

TA film treatment section


The TA film treatment section maintained a new shape with 500,000 shots and no maintenance , while maintaining good sharpness. Resin debris generated after punching is hard to adhere and the number of cleanings can be reduced.

Unprocessed part


The blade was re-polished after using 180,000 shots and 360,000 shots in the AB coating untreated part, and after about 500,000 shots, re-polishing became impossible and the blade was replaced.
