Product overview
The JTBY-240SV-365 is a versatile 240mm laser tube cutting chuck designed for tube laser cutting machines that process multiple types of metal profiles. It supports round pipes from Ø10 to Ø240 mm and square tubes up to 240 × 240 mm, providing a flexible clamping solution for a wide range of tube cutting applications.
In addition to standard round and square tubing, the chuck can also accommodate I-beams, channel steel, angle steel and other structural profiles within the specified processing range. For special workpieces that exceed the standard jaw configuration, customized jaws can be provided to match specific profile shapes and clamping requirements.
When used in a two-chuck configuration, the system supports a combined maximum load of 300 kg. With its broad profile compatibility and adaptable jaw options, the JTBY-240SV-365 is well suited for tube laser cutting machine manufacturers, equipment integration projects and replacement or retrofit applications requiring a practical 240mm chuck solution.

Application Scenarios
The JTBY-240SV-365 is suitable for a wide range of tube and profile laser cutting applications, especially where multiple workpiece shapes and sizes need to be processed on the same machine.

Round & Square Tube Cutting
Suitable for laser cutting of round pipes and square tubes within the specified clamping range, making it a practical choice for general tube processing applications.

Structural Profile Processing
Designed to handle I-beams, channel steel and angle steel, providing greater flexibility for manufacturers processing structural metal profiles.

Multi-Profile Production
Ideal for production environments where different tube shapes and profile types are frequently processed, helping reduce the need for separate clamping solutions.

Tube Laser Machine Integration & Retrofit
Suitable for new tube laser cutting machine builds, OEM integration, equipment upgrades and chuck replacement projects, subject to machine interface and installation requirements.
Machine Compatibility
The JTBY-240SV-365 is designed for integration with tube laser cutting machines that require a 240mm clamping range and flexible processing of round, square and structural profiles.
Machine compatibility depends on several factors, including the mounting interface, flange dimensions, transmission ratio, drive configuration and available installation space. Both front and rear chuck configurations should be checked against the machine design before installation.
For new machine builds, OEM projects or replacement applications, customers are recommended to provide the machine model, interface dimensions, installation drawings or existing chuck specifications for compatibility confirmation.
If the standard configuration does not fully match the machine structure or workpiece requirements, customized mounting or jaw solutions may be available based on the application.
Customization Options
The JTBY-240SV-365 can be adapted to specific workpiece and machine requirements, helping customers obtain a more suitable clamping and integration solution for different tube and profile applications.
Custom Jaws for Special Profiles
Customized jaws can be provided for workpieces with special shapes, non-standard profiles or dimensions that exceed the effective range of the standard jaw configuration.
Machine Interface Adaptation
For OEM integration, replacement or retrofit projects, the chuck configuration can be adapted according to the machine structure, mounting interface and installation requirements.

Profile-Specific Clamping Solutions
Jaw geometry can be adjusted according to the workpiece profile and clamping requirements, providing a more suitable solution for structural sections and irregular metal profiles.
Customized Technical Drawings
Technical drawings can be provided according to the customer's application and installation requirements. Customers may also provide machine interface dimensions, existing chuck drawings or workpiece specifications for technical evaluation and drawing confirmation.
Based on the tube size, profile shape, workpiece weight and machine configuration, our team can recommend a suitable chuck setup and provide corresponding technical documentation for project evaluation.
FAQs
Can the JTBY-240SV-365 handle special or irregular profiles?
Yes. For non-standard or irregular profiles, the clamping solution can be evaluated according to the workpiece shape and dimensions. Customized jaws may be provided when the standard jaw configuration cannot meet the required clamping geometry.
Can you provide technical drawings before installation?
Yes. Technical drawings can be provided according to the customer's machine structure, installation requirements and project needs. Customers can also provide existing chuck drawings, mounting dimensions or machine interface information for technical confirmation.
Can customized jaws be supplied for structural steel profiles?
Yes. Customized jaws can be designed according to the profile geometry and clamping requirements. This is particularly useful for structural sections or special profiles that cannot be properly supported by standard jaws.
What should I provide when requesting a customized solution?
For faster technical evaluation, please provide the workpiece drawing, profile dimensions, maximum workpiece weight, machine model, mounting interface dimensions and any special clamping requirements. Based on this information, a suitable chuck configuration and corresponding technical drawings can be prepared.
