Competitive Strengths
1. High in cutting ability
* Max tube size: 500mm
* Max weight of single tube: 2000kg
* Cut round, square, rectangular, oval tubes, angle, channel, H-shaped steel, as well as I beam
* Deal with high-reflectivity tubes like stainless steel and AL alloy because of its multi-layer anti-reflective structures
2. Cut with 0 tailing
Due to 7-axis linkage and reverse cutting of three chucks, 0 tailing will come true for the max tube utilization rate.
3. High-precision cutting
Its innovative dynamic 7-axis tube pulling function may correct the tube deformation to a certain degree, just for cutting at high precision.
4. Need less costs of production
As for its laser generation, the electro-optical conversion rate reaches over 40%. Electric power and cutting costs will be greatly saved for users.
Mechanical Benefits
- Classic design
* This is a large-sized machine, covering a relative large area.
* To cut long tube, its control system sits in the middle and cutting area runs through it to facilitate the full-course movement of three chucks, as thus, long tube is handled easily.
- Autofocus laser cutting head
* Small in size and light in weight, with all-optical temperature detection
* Autofocus and auto obstacle avoidance functions can make sure of high cutting precision and prevent possible collision.
- Three pneumatic chucks
* Full-stroke chucks mean that they can move at will in whole stroke, which helps to keep tubes stable during cutting
* Dual-rail sliding blocks are used to improve the ability to clamp heavy tubes
* There is also through-beam sensor that can detect tube position and enable automatic clamping
- Side-attached machine tool bed
* It is designed as triangular, with high stability and large loading capacity
* The bed is made of three segments. Each is outfitted with lifting holes to facilitate transport at less costs
* Through fine welding, annealing stress relief, secondary aging treatment, as well as precision finishing, it will be full of high rigidity and long service life.
- Follow-up support
* The servo-controlled support can adjust tube supporting height based on actual diameter until tube is coaxial with chucks center. It usually cling to tube surface.
* This support is used to prevent low precision caused by long tube sagging and heavy tube’s rigid impact on the machine during unloading.
- Automatic loading & unloading devices
* Loading device, composed of tube conveyor and supporting racks, will feed tubes into cutting area automatically.
* The segmented unloading device works with multiple groups of receiving units to adapt to tubes of different lengths.
Control System Benefits
The intelligent bus-based CNC system is special for three-chuck tube laser cutters. Based on real-time bus system, it allows for faster and more stable cutting of corners. Other special-shaped steels are also handled easily.
- Automatic nesting software
Besides high automation, it can also realize co-edge nesting to minimize cutting times and save raw materials to the utmost.
- Tube deviation compensation
Make low demands on tubes while clamping, raising piercing and cutting accuracy
- Automatic obstacle avoidance
Apply to both chucks and laser cutting head that can prevent collision and need less maintenance

Optional Benefits
1. ±45° bevel cutting
The machine can cut tubes into ±45° bevel in one go. With less procedures, tube cutting efficiency will be greatly raised.
2. Safety fence
The machine may work with safety fence to separate cutting area. It is good for preventing man-machine injury or unexpected shutdown caused by workers’ intrusion by mistake.

What is the cutting capability of lasers of different powers?
The power of a fiber laser directly impacts its cutting capabilities. Fiber lasers with different power levels are suitable for various material thicknesses and types. The following article provides an overview of the cutting capabilities for the main power ranges: Cutting Capacity and Speed of 1.5kW-80kW Fiber Lasers
What should you pay attention to while maintaining a laser cutter?
Laser cutter can cut a wide range of materials, incl. stainless steel, carbon steel, alloy steel, silicon steel, aluminum, aluminum alloy, galvanized sheet, aluminum-zinc plate, pickled sheet, titanium, and other metal sheets. They can be applied in most metalworking industries, such as sheet metal working, kitchenware, aerospace, electrical cabinet, household kitchenware, automotive parts, construction and agricultural machinery, and more.
What advantages does a laser cutter have compared to other traditional cutting modes?
Laser cutting replaces traditional mechanical blades with an invisible beam of laser, offering high precision, fast cutting, no limitation on cutting patterns, automatic nesting to save materials, smooth cut edges and low operating costs. It is gradually improving or replacing traditional metal cutting processes.
* The mechanical parts of laser cutting head don’t contact workpiece, preventing surface scratches during operation.
* Laser cutting is fast, with smooth and flat edges that typically require no further processing.
* The heat-affected zone is small, resulting in minimal deformation of sheet and narrow cutting seams (0.1-0.3mm).
* Cuts have no mechanical stress nor shear burrs.
* High cutting precision and good repeatability without damaging the material surface.
* CNC programming allows for the processing of any flat pattern and the cutting of large entire sheet without the need for molds, saving both time and costs.
What is the warranty period of laser cutter?
The complete machine is under 2-year warranty. Its main accessories and consumables will be replaced depending on their specific service life. We also provide original accessories for global users, with quotes available within 24h and delivery within 3-7 working days. The change of these accessories will be given priority to our nearby subsidiaries or local service centers.
Does laser tube cutting machine have auto-correction function?
Yes. Our machines are usually equipped with advanced CNC systems that use capacitance centering to measure tube’s actual size and automatically calibrate to align the tube profile with its model. It also features real-time compensation for tube deviation, reducing requirements for tube clamping and improving the tube piercing accuracy.
