PBT CNC Bender, Model PBT35 PC300 with Mandrel Device

Industry: Roll Over Protection Structures

Published on Wednesday, November 30, 2016.

The Company

A large supplier of value added roll formed tubes of various profiles needed to supply their customers with finished ROPS.

The Issue

The profiles have thick walls and odd shapes. The final bent shapes of the ROPS often have multiple radii, blended radii and unique features to set the customer’s products apart from the competition.

The Solution

After looking at several 3-roll CNC benders, the subject company came across PBT. Finding that PBT has years of international experience in bending tubes for ROPS, the company asked for a proposal for a complete solution.
Sample profiles were shipped to PBT where tools for the specific profile were made and test bends were completed. The complete solution included a full CNC machine with integrated 3rd axis and mandrel unit with a hydraulically powered “booster”.
The manufacturer was impressed the professional nature of the machine, installation and support provided in the US by PBT and Boschert Precision Machinery.
Another unique application solved with standard solutions by PBT!
