What is Electric Discharge Machining?

Electric Discharge Machining (EDM) is a non-contact thermal erosion process that uses electrical discharges to remove material from electrically conductive workpieces. Wire EDM, a specialized form, employs a traveling wire electrode to cut intricate shapes and contours with high precision, especially in hard or heat-resistant materials. The process offers advantages like producing complex geometries with tight tolerances, accurately machining narrow slots and small holes, and maintaining superior surface finish, making it invaluable in applications requiring precision and quality control.

They do what they say they'll do. Sometimes they even finish sooner than promised. If we have any problems or questions, they always give us helpful answers. You can count on them.


UTM is an extremely professional company with great customer service. Everything we ordered arrived as expected. There were some initial problems, but Kobe helped find a solution that worked for both sides. We will definitely use them again.


For my last order, the customer support was amazing. Kobe helped me solve a logistics issue and the algo parts were excellent quality as expected. I'm super happy with the support and service. For my next order, I'll be increasing the number of parts since I know the quality and service will be great.

Andres C

I ordered 50 CNC machined stainless steel parts and they turned out great. The dimensions were right on and the parts were clean and smooth. I'll definitely order from them again.
