Ultimaker metal shaft informations ?


Recommended Posts

Posted · Ultimaker metal shaft informations ?

Hi,

I am looking for the specific reference of the 6,8,12mm metal shafts used in the Ultimaker, to replace them with longer ones for a larger version of the printer. I already have some but the diameter accuracy is too average and the metal is not hard enough. I struggle to find accurate informations about what is needed exactly. The problem being that in the lengths needed (between 50 - 60 cm) I can't find it on 3D printer's dedicated website and have to order directly from industrial specialists like Misumi.

Material : High-Carbon Steel ?

Finish : Chrome ? Nickel ?

Hardness : 58-62 HRC or more ?

Diameter accuracy : h5, h6, h8 ?

Anybody has an idea ?

    h6 tolerance (h5 too expensive, h8 too rattley)

    Silver steel ground and polished (carbon/chromium through hardening steel)

    42HRc min (62 is way overkill and will be for sure be a special order only)
