AQT-HT Laser Cutting Machine for Medical Bellows & Spiral Tubes – Precision Micromachining of Flexible Tubes
The AQT-HT Laser Cutting Machine is specially designed for high-precision micromachining of thin-walled, flexible medical tubes, including bellows, spiral tubes, and flexible hypotubes. It delivers consistent, high-quality cuts with excellent repeatability, enabling manufacturers to create complex geometries without compromising structural integrity.
Built with a robust mechanical platform, ultra-stable laser delivery optics, and advanced motion control, this system handles delicate tube geometries while keeping thermal deformation minimal. Its capability to process intricate spirals and bellow shapes makes it an ideal solution for advanced medical device manufacturing
Scope of application
This machine is tailored for applications involving medical bellows, spiral tubes, flexible hypotubes, spring-type structures, and other thin-walled tubular elements used in minimally invasive medical devices. It supports geometries with varying pitch, amplitude, and curvature, enabling design freedom for manufacturers of catheters, stents, actuators, and flexible tool segments.
Advantages:
- Ability to cut complex spiral patterns, bellows folds, waveforms, slots, and cutouts without mechanical stress
- Minimal heat-affected zones and burr-free edges, reducing the need for secondary finishing
- High throughput and consistent reproducibility across batches
High finishing
The AQT-HT produces exceptional surface integrity thanks to precise control of the laser beam, focus dynamics, and assist gas parameters. The system is engineered to maintain near-constant kerf width and edge straightness even in curved or spiral patterns, ensuring that the final parts meet tight tolerances and aesthetic requirements.
Advantages:
- High smoothness of inner and outer tube surfaces
- Uniform kerf width with negligible taper
- Low residue and virtually no need for post-processing
Strong adaptability
The AQT-HT adapts readily to a range of medical-grade alloys commonly used in flexible tube components, including stainless steels, nickel-titanium (nitinol), cobalt-chrome alloys, and titanium. Its control system permits dynamic adjustment of power, pulse settings, traverse rates, and assist gas composition, allowing fine-tuning of processing parameters for each material.
Moreover, it handles a variety of tube diameters and wall thicknesses, giving manufacturers flexibility to work on both ultra-thin walls and more robust spiral tubes. Whether you need micro-bellows with tight folds or larger amplitude spirals, the machine supports those variations without mechanical modifications.
Flexible design
Engineered with modular fixture systems and an adaptive head path design, the AQT-HT can accommodate tubes with different diameters, lengths, and shape profiles. The cutting head path can be programmed to follow complex 3D trajectories to realize angled cuts, internal features, or non-uniform spiral geometries.
- Easily swappable fixtures for different tube sizes
- Programmable 3D head motions for non-uniform spiral and bellow patterns
- Integration options for automated tube feeding, unloading, and in-line quality inspection
Technical certification
The AQT-HT is built in compliance with medical device manufacturing standards and supports traceability, clean-room compatibility, and safety controls in line with regulatory requirements. The machine’s design ensures reliable process stability, documented repeatability, and integration into quality-controlled production environments.
