1.4057 - AISI 431 Centerless bar precision grinding
Steelinox B.V. supplies centerless ground barsv, in diameters from ø2 to ø 250 mm en lengths up to 13 meter, depending on availability.

We can offer precision grinding to a tolerance of 0,013 mm with a surface finish of Ra 35 ( or better, depending on diameter and grade)

Grinding can be performed on pieces with a minimum length of 2.5 meters. Although it is possible to saw the shafts after grinding, we do not recommend this because of the risk of damage .

Applications: shipping (propeller shafts), hydraulic industry (hydraulic cylinders).

Note: The axes can be aligned to the tolerance specified by you.
