Precision Zero-Tail Design
Designed for high-precision laser tube cutting applications, this precision zero-tail chuck helps reduce material waste and supports efficient tube processing with minimal tail material.
Wide Clamping Range
The chuck supports round tubes from Ø8 to Ø165 mm and square tubes up to 165 × 165 mm, making it a versatile laser tube chuck for round and square tubes.
Multiple Profile Compatibility
In addition to standard round and square tubes, the chuck can also handle I-beams, channel steel up to No. 10, and compatible special-shaped profiles, providing greater flexibility for different metal processing requirements.
120 kg Dual-Chuck Load Capacity
The front and rear chucks provide a combined maximum load capacity of 120 kg, ensuring stable support for tubes and profiles during laser cutting operations.
Custom Auxiliary Jaws Available
For special-shaped profiles that exceed the standard jaw length, custom laser chuck jaws or auxiliary jaws can be provided according to the workpiece dimensions and clamping requirements.
Suitable for Laser Tube Cutting Systems
The chuck is designed for integration with laser tube cutting machines and automated tube processing systems where precise clamping, profile versatility, and stable workpiece support are required.
Clamping Range & Compatible Profiles
The JTBY-160PZ-305 is designed to handle a wide range of metal tubes and structural profiles, making it suitable for laser cutting applications with different workpiece shapes and sizes.

Round Tube
The chuck supports round tubes with a clamping range of Ø8–Ø165 mm. This makes it suitable as a laser chuck for round tube processing across a broad range of tube diameters.

Square Tube
For square tube applications, the maximum clamping size is 165 × 165 mm. The chuck can be used as a laser chuck for square tube cutting where stable and accurate clamping is required.

I-Beam & Channel Steel
The chuck is also compatible with I-beams and channel steel up to No. 10, providing a practical clamping solution for structural steel processing. It can be applied as a laser chuck for I-beam and a laser chuck for channel steel within the specified clamping range.

Metal & Special-Shaped Profiles
The chuck can accommodate compatible metal profiles and special-shaped tubes within the standard jaw range. For workpieces that exceed the standard jaw configuration, customized auxiliary jaws can be supplied according to the profile dimensions and clamping requirements.

Applications
The JTBY-160PZ-305 is designed for integration into fiber laser tube cutting machines, zero-tail cutting systems, and automated tube processing equipment. It provides stable clamping for a variety of tube and structural profile cutting applications.




This tube laser cutting machine chuck can be integrated into fiber laser tube cutting machines and automated pipe processing systems for round tubes, square tubes, structural profiles, I-beams, and channel steel. It also serves as a reliable chuck for laser tube cutting machine applications requiring flexible profile compatibility and stable workpiece support.
For manufacturers building customized tube cutting systems, the JTBY-160PZ-305 can also be used as a laser pipe cutting chuck in equipment designed for multiple tube shapes and structural profiles.
Custom Jaw Solutions
For special-shaped tubes and metal profiles that exceed the standard jaw configuration, custom auxiliary jaws can be provided according to the workpiece dimensions, profile shape, and clamping requirements.

Custom Jaws for Special Profiles
The standard jaws are designed to handle compatible tubes and profiles within the specified jaw length and clamping range. For oversized, irregular, or non-standard profiles, customized auxiliary jaws can be developed to improve clamping stability and ensure proper workpiece positioning during laser cutting.
Our custom laser chuck jaws can be adapted for applications involving special-shaped tubes, structural profiles, and other non-standard workpieces that cannot be securely clamped with standard jaws.
To evaluate whether a customized jaw solution is required, please provide:
Tube or profile shape
Workpiece dimensions
Cross-section drawing
Material type
Workpiece weight
Required clamping position
Send us your tube shape, dimensions, and profile drawing for chuck compatibility evaluation. Based on your workpiece information, we can recommend a suitable custom tube chuck jaw solution for your laser cutting system.
fAQs
Is the JTBY-160PZ-305 suitable for zero-tail laser tube cutting systems?
