Barres de carbur sòlid de tungstè per a freses i trepants d'alta qualitat estable
1.Les varetes de carbur sòlid de tungstè estan modelades per premsa per modelat o extrusió.
2.Les barres de carbur sòlid de tungstè estan sinteritzats per un forn integrat de sinterització de baixa pressió, per tant, el rendiment general és alt.
3.La barra rodona rugosa de carbur de tungstè-cobalt o el diàmetre exterior de la barra rodona es pot refinar i polir segons qualsevol tolerància. Les toleràncies comunes són h5, h6, -0,005, etc., i el xamfrà final de les barres de carbur també es pot processar.
4.Les barres de carbur és adequades per al processament d'acer general, ferro colat, acer inoxidable, acer resistent a la calor, base de níquel i aliatge de titani. Recomanat per a materials d'eines de carbur de propòsit general, com ara broques giratòries, freses d'extrem, aixetes i broques de pistola.
