Marudai Precision Co., Ltd. offers a lineup of 15 wire-cut electrical discharge machining (EDM) machines tailored to meet customer needs.
We offer a range of machines, including those with machining accuracy of ±2μm, equipped with automatic core removal robots, high-speed small-hole EDM machines, and large machines with a maximum machining size of 750 x 500 x 310 mm.
We have certified Grade 1 and Grade 2 electrical discharge machining technicians on staff, and we are constantly striving to improve our employees' skills.

Wire-cut electrical discharge machining (EDM) machines utilize automatic wiring to enable unmanned operation at night, and equipment equipped with an automatic core removal robot achieves complete automation from workpiece setting to finishing.
We offer services that meet both the demands of shorter delivery times and high-precision machining.
Furthermore, we provide sub-micron precision through the traditional "scraping" technique (which achieves high flatness and sliding properties).

A fitting process created by a group of specialists dedicated solely to wire-cut electrical discharge machining.
- Packed with know-how, completed using only a single clamping claw, without the need for vises or specialized jigs.
・It's truly magic! The allure of clearance
- State-of-the-art equipment and the masterful skills of electrical discharge machining technicians are perfectly combined.

From "Can we really process something into this shape?" to the surprising realization, "Wow, we did it!"
Asymmetrical shapes at the top and bottom, or tapered designs, tend to make the wires more prone to breakage.
However, at Marudai Precision, we handle the processing conditions and programming of the equipment, as well as the taper specifications, etc.
Leveraging our years of expertise, we provide products that satisfy our customers.

・From "It's probably impossible, so I'll give up" to "Let's try asking, even if it's a long shot," to Marudai Precision!
Because we use wire-cut electrical discharge machining, we can handle even the most challenging machining tasks, such as thin-walled construction and ultra-fine grooving.
As long as electricity can be conducted, materials such as graphite, conductive ceramics, stainless steel, Inconel, and titanium can be processed.
