ingle, modest processes are often the key step processes. For instance, chipless tube cutting allows direct processing of the tube. In the ongoing development of its “t cut” focuses on two aspects, including chipless cutting of thick-walled pipes.
There are good reasons for chipless cutting, as contamination series production of a variety of tubes. In the worst case, the chips appear again when the tubes are already installed in the system. If you manage to contain such an event, the chips may only cause faults. In the worse case, the destruction of entire system components may be the result. “This makes the advantages of chipless cutting the added advantage of chipless cutting, is that it can be deployed in a wide range of equipment variants to meet individual requirements”, explains Gerd Nöker, Managing GmbH. When the tube is cut from the coil, it is precisely aligned, checked for damages and fed to the orbital cutting unit. Here you either work with two coils that are connected to each other, in order to save set-up time, or you use the unit‘s feeding assistance system which mounts in a new coil quickly and securely. During the cutting process the tube rods are fed via a magazine and separation unit. To save additional material, our unit also system. This system ensures that, ideally cut lengths without a residual length. The cutting material is positioned by a gripper feeder which has a servo-electric drive. The cutting meter feed.
The cutting process itself is performed by an orbital cutting knife. The big advantage of the plant is

that this cutting knife is mechanically positioned in a controlled manner. In cutting process to precisely suit the wall thickness of the material being cut. The cut area is intentionally opened during the cutting process, thus ensuring that the cutting rollers The tube is separated at the precise moment when the optimal cutting depth is reached. This guarantees that pipe constriction is kept to a minimum. In addition, a special mechanism guarantees that the pipes are continuously calibrated on the exterior. Of course we use knives in our units, which are optimally This ensures that the cutting knifes possible even with welded pipes. The depending on the pipe length. Standard cutting can be realized equipped, our technology can also The shortest cutting length with
without the pull apart procedure it is runs at the best cycle times with the cut pipes can be discharged as available for this purpose. The there. The extremely high output of our cutting machines makes this necessary. This system allows
several subsequent processing steps to be serviced. A special software program controls the cut optimisation system, which ensures minimal scrap and thus saves material.
