- 2-in-1 technology for highest accuracy and flexibility
- calibration and straightening of pipe in one machine
- quick and easy tool change
Calibrating and straightening in one machine. Graebener® calibration and straightening presses are efficient and economic multi-purpose machines which offer the highest possible flexibility for the production of LSAW pipes. Welded pipes are calibrated and straightened to the set dimension in your Graebener® calibration and straightening press. The press tool is of a modular and therefore cost efficient design.
We have developed our technology further following the ever increasing market requirements for flexibility of lot sizes. Our newest machine development, the combined Graebener® calibration, straightening and crimping press allows you to benefit from a patented 4in1 technology. Pre-bending respectively crimping of plates, calibration of pipes, straightening of pipes and even bending of already formed pipes, all of this in one single machine. This concept is unmatched worldwide.
Benefit now from
External pipe diameter:
up to 64" (1,625 mm)
up to 60 mm
The design of the Graebener® calibration and straightening presses is based on decades of experience in the pipe industry as well as the constant interaction and collaboration with our customers and partners. The result of this are individual customized solutions which provide you with the decisive competitive edge. The new combined Graebener® calibration, straightening and crimping press is one proof among many worldwide for this successful approach.
When designing the press, we pay special attention to offer you as machine operator the highest possible flexibility to be achieved with a multi-purpose technology. For this reason, we also designed the tool change to be fast and operator-friendly. The change is carried out right next to the machine by moving the tool sideways out of the press reinserting it after the tool change. This saves time and money.
To ensure optimum results your Graebener® machine is equipped with a controlled ram for the closing, pressing and opening of the tools. The ram cylinders are designed as controlled axes thus ensuring an acceleration without pressure peaks and a controlled deceleration.
