Advantages of honing tubes
1, improve the surface roughness, the
roughness can basically reach Ra≤0.*8µm
2, correct roundness,
ellipticity can be ≤0.*1mm
3, improve the surface
hardness, eliminate stress and deformation, hardness increase
HV≥4°
4, residual stress
layer after processing, fatigue strength increased by
*0%
5, improve the quality
of the fit, reduce wear, extend the service life of parts, but
reduce the processing cost of parts
Our tubing is available in honed or unhoned variations in popular
metric and imperial sizes from 2 to *0 inches and *0 to **9mm. If
you cannot find a standard size to suit your needs, well
manufacture it.
1.Main material: St*2 BK+S (E**5 SR)
2.1.Main material: SUS**4L BK+S (TP **4L)
After cold drawing, the tubes are subjected to stress relief heat
treatment.
We offer 2 types of production:
ï‚·Ready for honing tubes: ID tolerance *0,2 mm *0,3 mm
ï‚·Ready for burnishing tubes: ID tolerance *0,6 mm *0,9 mm
The tubes are cold drawn, heat treated and straightened
(1/***0).
Honed tube is well known as the best material to manufacture
hydraulic cylinders. This is because honed tubes are the most
critical materials for hydraulic cylinders. Honing is essentially a
bore sizing and surface preparation process
