Product Overview
The JTBY-230SV-350 is a 230mm simple-version tube laser cutting chuck designed for laser tube cutting machines handling large-diameter pipes and structural steel profiles. Its square and round hole design supports different workpiece shapes, including round pipes, square tubes, I-beams, channel steel and angle steel within the specified clamping range.
With a round pipe capacity of Ø15–Ø230 mm and square tube compatibility up to 230 × 230 mm, this model provides a practical clamping solution for manufacturers working with various metal tube sizes. The front and rear chuck configuration has a maximum combined load capacity of 300 kg, making it suitable for compatible tube laser cutting machine configurations with demanding workpiece requirements.
The JTBY-230SV-350 also supports selected structural profiles, including I-beams and channel steel up to No. 15, as well as angle steel up to No. 12. For special-shaped workpieces that exceed the effective jaw length, customized jaws can be considered after evaluating the actual profile dimensions.
For machine manufacturers and equipment integrators, the defined front and rear dimensions and flange specifications provide important reference points for machine integration and replacement projects.

Workpiece Compatibility and Applications
The JTBY-230SV-350 is developed for tube laser cutting machines used in metal fabrication and structural profile processing. Its 230mm working range makes it suitable for applications involving larger metal tubes and selected structural sections.

Round Pipe Cutting
Suitable for round metal pipes with diameters from Ø15 mm to Ø230 mm. Typical applications include industrial piping, metal frames and tubular components.

Square and Rectangular Tube Processing
Designed for square tubes up to 230 × 230 mm, subject to the specified circumscribed-circle limit and jaw geometry. Actual rectangular tube compatibility should be checked before ordering.

I-Beam and Channel Steel Processing
Supports compatible I-beams and channel steel up to No. 15. The actual section dimensions and clamping position should be evaluated to ensure secure contact with the jaws.

Angle Steel Processing
Suitable for compatible angle steel up to No. 12, depending on profile dimensions and jaw configuration.
Machine Compatibility and Installation
When selecting a tube laser cutting chuck for a new machine or replacement project, mounting dimensions and flange specifications are important factors to check. The JTBY-230SV-350 is designed with defined front and rear dimensions to support machine integration and installation assessment.
The chuck features a 350 mm front dimension and a 145 mm rear dimension. These measurements provide key dimensional references for evaluating installation space, mounting arrangements and compatibility with the machine structure.
Mounting and Flange Specifications
The JTBY-230SV-350 comes with the following flange and transmission specifications:
Front Flange: 110, transmission ratio 1:4
Rear Flange: 90 (110), transmission ratio 1:3
These specifications should be checked against the machine's mounting interface and transmission configuration before installation. For replacement projects, buyers are advised to compare the existing chuck drawings and flange dimensions to avoid mismatches.
Installation and Machine Integration
For tube laser cutting machine manufacturers and equipment integrators, proper installation requires consideration of more than the chuck's external dimensions. The mounting position, connection interface, transmission arrangement and available installation space should all be evaluated.
