K35 Heavy-Duty Fiber Laser Tube Cutting Machine | Large Diameter Pipe Cutter |- LX Laser

The K35 Heavy-Duty Fiber Laser Tube Cutting Machine is a powerhouse designed for the most demanding industrial applications. It breaks the limits of traditional tube processing, offering unmatched stability and precision for large-diameter and overweight metal pipes.

• Max Diameter : Up to 350mm (Optional 450mm)

• Max Payload : Up to 1000kg+ per tube

• Chuck System : 3-Chuck  Intelligent System 

• 
  

Core Advantages 

1. Zero Tailing Technology (3+1 Chucks) 

The K35 is equipped with an intelligent three-chuck system that enables zero-tailing cutting. This significantly reduces material waste and lowers the production cost for expensive heavy-duty pipes.

2. Heavy-Duty Bed & Super Load-Bearing

Built with a reinforced machine bed and heavy-duty rollers, the K35 can easily handle pipes weighing over 1 ton. It ensures no deformation during high-speed rotation and cutting.

3. Versatile Profile Processing

Beyond standard round and square tubes, the K35 excels at cutting H-beam, I-beam, Channel steel, and Angle steel.

4. Automatic Loading for Heavy Tubes 

Optional automatic loading system designed specifically for heavy pipes reduces manual labor and maximizes production efficiency.

Q1: What types and sizes of metal tubes and profiles can the LX-K35Ⅲ-5-66 laser tube cutting machine process?

The LX-K35Ⅲ-5-66 is a high-precision fiber laser pipe cutter engineered for large and heavy structural metal profiles:

• Round Tubes: Diameter from  40mm to 350mm. 

• Square Tubes: 40* 40 mm to 350* 350 mm

• Structural Steel Profiles: Supports national standard Channel Steel (13.7# to 32#), Equal Angle Steel (50* 50 mmto 250* 250 mm), I-beams (10# to 32#), and H-beams (up to 350* 350 mm).

• Maximum Load Capacity: Handles a single-pipe weight of up to 1,300 kg (216kg/m) with a maximum loading length of 6,000 mm

Q2: How does the LX-K35Ⅲ-5-66 ensure cutting accuracy and prevent heavy tube sagging?

To maintain high precision during heavy-duty CNC metal tube laser cutting, the machine integrates several advanced mechanical design features:

1. Side-Mounted Bed & Welded Frame: The side-mounted structural bed undergoes high-temperature annealing and gantry milling to eliminate dynamic stress, guaranteeing vibration resistance and long-term stability.

2. Follow-Up Support System: Active follow-up supports prevent long and heavy tubes from sagging during rotation, maintaining a positioning accuracy of ±0.05mm/1000m and repeat accuracy of ±0.03mm

3. Automatic Tube Centering: Built-in four-sided automatic center calibration neutralizes minor tube deformations or twists

Q3: What is the benefit of the full-stroke pneumatic chuck system in this fiber laser pipe cutter?

The LX-K35Ⅲ-5-66 is equipped with a 360*360mm square-hole full-stroke pneumatic chuck system:

• Wider Processing Range: Clamps a broader range of square/rectangular pipes without manual jaw adjustments.

• Ultra-Short Tailing (Zero Tailing Potential): Under optimized nesting software layouts, the front chuck actively moves to avoid interference, enabling minimal tailing waste (tail length down to 20 mm) and significantly lowering raw material costs.

• High Clamping Force & Speed: Delivers smooth rotational positioning (up to 60 rpm) without tube twisting or deformation.

Q4: What laser powers are available, and what are the maximum cutting capacities?

This heavy-duty industrial laser tube cutter supports fiber laser power options from 6,000W to 12,000W (Maxphotonics / Raycus):

• Carbon Steel: Maximum cutting thickness up to 25 mm (using O₂ gas).

• Stainless Steel: Maximum cutting thickness up to 16 mm (using Nitrogen or compressed Air).

• Aluminum Alloy: Maximum cutting thickness up to 14 mm.

(Note: Maximum processing speeds reach up to 15 m/minfor thinner-walled tubes.)

Q5: What industrial applications benefit most from the LX-K35Ⅲ-5-66 tube cutting laser machine?

Due to its heavy payload capacity and profile cutting capabilities, the LX-K35Ⅲ-5-66 is widely utilized in:

• Steel Structures & Building Bridges

• Heavy Engineering Machinery & Tower Crane Manufacturing

• Petroleum & Chemical Pipelines

• Shipbuilding & Special Vehicle Chassis Manufacturing

• Subcontracting Laser Tube Processing Services

Q6: What warranty and technical support services are provided by LONGXIN LASER?

LONGXIN LASER offers a comprehensive global customer support framework:

• 1-Year Warranty: Full machine warranty (excluding laser source warranties per manufacturer and standard wear-and-tear consumables).

• Lifetime Technical Support: Free lifetime software updates and online/remote technical consulting.

• Fast Field Response: 24/48-hour rapid on-site dispatch support for troubleshooting and installation training.
