Examples of processed tungsten carbide

Tungsten carbide is a high versatile material used for metal molds, cutting machines, etc. OGURA is providing various tools with wear and abrasion resistance by machining tungsten carbide to various kinds of shapes.

Especially, OGURA is good at machining smooth inner surface with good fluidity used as nozzles and dies. And we are able to polish up inner surface of holes with high precision diameter. What is more, we are also good at machining micro tip end just like push-up pins.
