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.
Processing tungsten carbide
Tungsten carbide
Very low variance of measurement of R at every corner of four-sided hole
- Measured value R1=R0.3786
- Measured value R2=R0.3787
Tungsten carbide
Make tip-end R with 25µm ± 2µm
- Measure value of tip end: R=24.1µm
- Circularity of tip end: 0.9µm
- Polished to a beautiful cubic shape
