The peeled bar is supplied in a polished and straightened condition. This allows for smoother surface finish, closer tolerances and better straightness, plastic forming as well as further machining. Peeled bars gives customers the opportunity to rationalise production and reduce production costs. The extraordinary cleanliness of the steel reduces the risk of unexpected tool failures and downtime, and the excellent straightness minimises the risk of shocks and vibrations that can occur at high cutting speeds.
Peeled bar is manufactured in sizes between 20 and 75 mm diameter.
Diameter tolerance and surface roughness
|Diameter, mm||Tolerance||Surface roughness Ra urn, max.|
Bars are normally delivered in lengths between 4 and 6 metres. The delivery lengths for heat treated bar are different as per Customers requirements.
Bars are normally delivered with the end surface cold sheared. We can also deliver bar with the ends cut square. Deburring or chamfering of one or both ends is available to special order.
The straightness tolerance is normally 0.0006 x L. The minimum gauge length is 1 metre.
Out-of-roundness, measured as the radius difference according to ISO 1101, is a maximum of one third of the diameter tolerance.
