- Constantly excellent WC powder produced by our own factory.
- Spray drying tower and HIP sintering furnace
- Cryogenic treatment to remove the internal stress
For grinding:
- General h6 rods and h5 or h4 as required
- Straightness 0.01-0.05
- Circularity 0.01-0.05
- General Roughness Ra 0.4, and Ra 0.2 or Ra 0.05 as required.
What we can provide:
- Unground/Finished ground Solid carbide rods
- Cemented carbide rods with straight coolant holes
- Cemented carbide rods with helical coolant holes
- Cut-to-length rods
- End mills blank with 3/4/5 holes
Our finished ground rods could be h6/h5/h4 as per your requirements.
