Steel, carbide, ceramic and bronze guide bushes are produced with modern production technologies. They are available with round, square, hexagonal bore as well as different profiles, in standard or ultra precision quality, with straight, slanted or silicone filled slots. Upon request, a guide can be put into the guide bush in order to facilitate the entrance of the material. For traditional steels and brasses, the carbide guide bush is fully adapted. While manufacturing stainless steels, as 316L or else or some titanium, ceramic guide bushes as CERTECH or NEW SURF are specially recommended. For irregular material, we propose a bronze guide bush.
