Fives Bronx first introduced its six roll straightener in the 1940s. As a pioneer in the development of this type of machinery, Fives Bronx has promoted its use as the most cost-effective and flexible method of straightening metal. These machines have a unique design that allows even the thinnest walled tube to be straightened accurately without surface blemishes. Enhanced efficiency, improved quality, superior technology and safety are all fundamental elements that Fives Bronx stands for.

Achieving Results
Through experience and technical knowledge, Fives Bronx tube straightening machines deliver compelling solutions to the market by:
Enhanced Efficiency
Roll angles are quickly and easily adjusted to provide line contact with the tube surface over the maximum effective roll profile.
Set up time is minimized though our patented COMPuter Aided Setting System.
Improved Quality
Hydraulic lift mechanism on the roll entry automatically adjusts roll position to prevent damaging tube ends.
A range of heavy-duty style machines provide enhanced rigidity, with consistent straightness and roundness.
The COMPASS software package can be customized to provide management, maintenance and quality control information, including: calibration and wear compensation; maintenance information; fault finding; and mimic flow diagrams.
Superior Technology
Unique design allows thin walled tube to be straightened accurately without surface blemishes.
The ability to straighten at speeds up to 200 meters per minute (approximately 600 fpm).
Hydraulic lift mechanism with sensor automatically adjusts rolls to accept upset pipe.
Pressure sensing units may be fitted on each roll to provide an accurate indication of the pressure applied to the tube.
Safety
The drives are set in the back of the machine, away from the operator.
The machine operator has a complete view of the straightening process from the operating console.
