Cut tubes efficiently and without chips

Clean perfect cuts with controlled achievement of optimal cutting depth
SCHMALLENBERG, Germany - July 2, 2014 - PRLog -- Even a single special process may sometimes be the key to effective complete solutions to production processes. In this respect for instance, chipless tube cutting allows direct further processing of the tube. In the consistent further development of its “t cut” tube cutting technologies, transfluid focuses on two aspects, including also chipless cutting of thick-walled pipes.

Good reasons for chipless tube cutting
Because contamination may pose major problems to the 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 get off easily in such an event, the chips only cause faults. In worse case, the destruction of entire system components may result. "This makes the advantages of chipless tube cutting processes completely clear. And an additional advantage to chipless tube cutting is that it can be deployed in a wide range of equipment variants to meet individual requirements", explains Gerd Nöker, Managing Director of transfluid Maschinenbau GmbH.

Secure from the coil
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.

Rod without residual length
During the cutting process the tube rods are fed via a magazine and separation unit. To save additional material, our unit also offers an optional cut optimisation system. This system ensures that, for instance, a 6-meter long rod is ideally cut lenghts without a resudial length. The cutting material is positioned by a gripper feeder which has a servo-electric drive. The cutting tolerances are +/-0.1 mm for a one meter feed.

Precise adjustment to match wall thickness
The tube cutting process itself is performed by an orbital cutting knife. The big advantage of the plant is that this cutting knife is mechanically forwarded in a controlled manner. In this way we can optimally adjust the cutting process to precisely suit the wall thickness of the material being cut. The cut area is intentionally opened during the cutting process. This ensures that the cutting rollers do not jam in the gap of the cut. 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 additional, a special mechanism guarantees that the pipes are continuously calibrated on the exterior. Of course we use knives in our units, which are optimally adjusted to the respective materials. This ensures
that the cutting knifes have a long service life. Cutting outputs of 100.000-200.000 cuts are possible even with welded pipes. The cutting time is from 2 to 3 seconds depending on the pipe length.

Large / Small
Standard tube cutting can be realized within the parameter range 6-30 x 3 mm (stainless steel). Specially equipped, our technology can also cut significantly smaller pipes. A different size machine cuts tubes to an outer diameter of 76 mm. The shortest cutting length with pull apart is approximately 30 mm, without the pull apart procedure it is approximately 10 mm. The tube cutting machine runs at the best cycle times with cut lengths between 55 mm and 1,000 mm. After the cutting process the cut pipes can be discharged as needed. There are up to 10 stations available for this purpose. The different lengths are deposited 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 controls the cut optimisation system, ensures minimal scrap and thus saves material.
