Shafts

Sophisticated parts to drawings

  • the partial hardening, made of unhardened primary material
  • with high-precision, turning, drilling, milling and grinding
  • high dimensional accuracy, also keeping the tolerances of form and location
  • small-sized quiding columns
  • all common materials such as Cf59, Ck60, Ck45, X46Cr13, X90CrMoV18, and additional 42CrMoV4, 51CrV4

Surface roughness

to Ra 0,025 μm

Made-offs with the final processing

  • For all possible types (guide) used in machinery or elsewhere
  • materials as described above

Production length to 6000 mm diameter with 60-80 mm in the manufacturing tolerance h6 and h7. Other diameters and tolerances on request.

The guide shafts ready for final machining assembly - with ball bearing housings and grooves - worked as a fixed length.

Materials Cf 53 (some diameters and chrome-plated or hollow / tubular shaft), X46Cr13, X90CrMoV18.
