AQT-SB4 Laser processing center for endoscopic bending section
AQT-SB4 Laser Processing Center for Endoscopic Bending Section — Advanced Center for Complete Endoscopic Joint Processing
The AQT-SB4 is a full-featured laser processing center tailored for bending sections of endoscopes. It not only performs fine cutting and slotting but offers integrated features like opening (centripetal, vertical, compound), real-time vision monitoring, and software-driven flexibility. With its capability to handle wide pipe diameters and wall thicknesses, it addresses both small-diameter tubes and larger structural components.
Built to deliver high precision under demanding conditions, the AQT-SB4 supports continuous automatic feeding, operates in dry or wet modes, and is engineered for medical, industrial, and electronic endoscope manufacturers requiring minimal burrs, tight tolerances, and high throughput.
Scope of application
Applicable in the production of medical, industrial, and electronic endoscopes, especially for bending and joint sections such as “snake bone” structures. This machine can handle both equal-diameter tubes and reducer tubes, and even flat instruments, where bending sections must meet strict geometric and surface quality requirements.
Advantages:
- Wide compatibility: supports 304 & 316L stainless steel, Ni-Ti, L605 and similar alloys
- Seam width: 15–30 µm; Machining accuracy: ≤ ±10 µm
- Processing modes: cutting, drilling, grooving; opening features: centripetal, vertical, compound
- Clamping systems: precision D-type collets, ER series collets, three-jaw chucks
High finishing
The AQT-SB4 delivers outstanding finishing quality throughout the bending section. Cuts are clean and smooth, with very low occurrence of burrs. Seam widths stay within 15–30 µm, and its optimized laser process preserves surface integrity even at bent or complex joints.
Advantages:
- No burrs & high cut quality
- Smooth, precise incisions across varied geometries
- High efficiency thanks to automatic feeding and one-side wall cutting
Strong adaptability
Designed to be flexible across multiple production demands, the SB4 handles dry and wet cutting, drilling, and grooving. Its shape tolerance compensation and adaptive systems support thin-walled tubes and allow the machine to keep accuracy even when tube shape varies or when processing reducer sections. It supports both equal-diameter and varied-diameter tube openings, giving manufacturers freedom to work with diverse component designs.
Flexible design
The SB4 offers an ergonomic design with a user-friendly interface that simplifies operator control and monitoring. Optional machine vision enables real-time inspections during laser processing. The modular hardware and software configuration allow tailoring of functions and intelligent production management to customer specifications.

Medical-grade SUS304 stainless steel (austenitic chromium-nickel alloy), offering excellent corrosion resistance and mechanical properties.
316L Stainless Steel is a medical-grade austenitic chromium-nickel alloy renowned for its excellent corrosion resistance and biocompatibility. With a tensile strength of approximately 485–550 MPa and elongation up to 40%, it offers durability and flexibility without brittleness. Its low carbon content enhances weldability and resistance to intergranular corrosion, making it ideal for medical implants and instruments. Laser-machined for smooth, burr-free surfaces, it minimizes tissue irritation in sensitive applications.
Nitinol (NiTi), a nickel-titanium alloy, is renowned for its superelasticity and shape memory, making it a game-changer in medical applications. With a tensile strength of up to 1200 MPa and elastic modulus of 40–75 GPa, nitinol excels in demanding environments.
Cobalt-Chromium Alloys (L605) are medical-grade materials valued for their exceptional strength, corrosion resistance, and biocompatibility. With tensile strength ranging from 800–1500 MPa and hardness of 300–550 HV, they ensure durability in demanding medical applications. Ideal for implants and surgical tools, they support direct tissue contact with minimal reaction. Laser-machined surfaces provide smooth, burr-free finishes, enhancing performance in sensitive procedures.
