Perfect cuts with controlled achievement of optimal cutting depth
Even a single special process may 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 focuses on two aspects, including also chipless cutting of thick-walled pipes.
Good reasons for chipless 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 only cause faults. In worse case, the destruction of entire system components may result. “This makes the advantages of chipless cutting processes completely clear. And an additional advantage to chipless cutting is that it can be deployed in a wide range of equipment variants to meet individual requirements”, explains Gerd Nöker, Managing Director of
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.

feeder which has a servo-electric drive. The cutting tolerances are +/- 0.1 mm for a one meter feed.
Orbital cutting wheel feeds in mechanically controlled, to ideally match wall thickness
and separation unit. To save additional material, our unit also 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
Precise adjustment to match wall thickness The 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.
