StarCut Tube – highly precise laser cutting system with high throughput


Flexible component for endoscopes

Radial cut with two axes

Off-axis cut with 4 axes

Reduced costs of tube processing with lasers.

With the new automatic tube loader, suitable for dry and wet cutting, ROFIN's mar-ket-leading laser cutting system becomes a versatile tube processing center for automated series production.

Manufacturing of various, frequently miniaturized, products requires cutting or drilling of thin-walled tubes or profiles with micron-scale precision. The delicate tube material has to be machined without burrs or distortion and this is where laser systems like StarCut Tube offer inestimable advantages compared to chemical and mechanical ma-chining procedures.

One laser cutting step replaces several adjacent machining steps
Manufacturing of parts for implants, instruments or endoscopes from round or oval tubes usually requires numerous different machining steps. Techniques like drilling, milling or eroding are carried out as separate processes, slowing down overall manu-facturing speed. At the same time, the risk of production waste increases with each ad-ditional step.
The 4-axes CNC laser processing system StarCut Tube allows to transform numerous mechanical machining steps into a single laser processing routine. With CNC-driven rotary-, x-, y- and z-axes and a solid granite machine set-up, even taper-free or offset cuts are as easy as ultra-precise processing of oval tubes or flat parts.

Fully-automated tube loading
Streamlining the manufacturing process with a laser system also reduces the pro-cessing time of parts up to a length of 600 mm (to only a few minutes). Therefore, an automated material loading system has to provide constant tube supply for efficient series production. ROFIN developed a new tube loading module with a side-loading magazine for tubes of 3 to 30 mm diameter and up to 3 m length. A pivotable pilgrim step separation assures precise and gently handling of tubes with small diameters. Sophisticated grippers provide accurate and reliable tube feeding and the automated removal of residual material.

Wet cutting - easier than ever
The automated tube loading module is available for wet cutting as well. Wet laser cut-ting with burr-free and oxide-free cutting edges dramatically reduces necessary post-processing steps and offers huge potential savings.
The new wet cutting option dramatically reduces the additional efforts, which are char-acteristic for wet laser cutting processes. The entire water-cooling system has been in-tegrated into the main housing. It was designed with a special focus on easy operation and maintenance. The water tank is easily accessible and removable for water change. A drawer allows to remove finished part without interrupting the cutting process.

Fiber and ultrashort pulse lasers
The StarCut Tube can be powered with ROFIN's StarFemto FX or StarFiber FC laser sources and achieves contour accuracies better than +/- 5 µm. The femto sec-ond laser source provides pulses lengths down to 300 fs and wavelengths of 1030 nm, 515 nm and 343 nm. Pulses shorter than 1 ps are an essential prerequisite for true, cold material processing and distortion-free cutting and drilling of polymers.

Application development, laser solution and training from a single source
Optimum laser systems are just one part of the ROFIN-philosophy. Medium-sized com-panies expect way more from their partner than just selling them suitable laser systems. ROFIN's specialists take care of the employee's training, help setting up the first appli-cations and the application support provides unbureaucratic assist during the first months. If required, ROFIN even designs the production room according to laser safety standards,
With its various configuration possibilities and service and support from the world-leading laser manufacturer ROFIN, the StarCut Tube emerges as a prospecting solu-tion for fully-automated tube processing in a broad application range..


Looking forward to seeing you:
