Very low total costs of the equipment
Experience of Linsinger rail milling on
European railways
Already after first practical experiences the
analysis of the processing system has
shown excellent results: The Linsinger
milling technology in operation achieves
transverse profile tolerances of 0.2mm.
The required longitudinal profile
accuracies are:
a73
From ±0.01mm in area of wave
lengths 30-100mm
a73
±0.03mm in area of wave lengths 100-
300mm
a73
±0.1mm up to wave length 1000mm
These figures are requirements for
high-speed lines with travel speeds
over 280km/h.
These standards are obtained with the
Linsinger milling-grinding-principle with
an amazing and incomparable perfection.
The limit figures for surface quality
are at maximum 10 µm surface roughness.
