Yantai Dongruitai Welding and Cutting Equipment Co., Ltd. is one of the leading manufacturers and suppliers of sheet metal laser cutting machine in China. We are committed to providing high quality customized machines with low price. Welcome to wholesale the newest sheet metal laser cutting machine made in China here from our factory. 1 years warranty is available.
Manufactured by Dongruitai Laser, the sheet metal laser cutting machine is engineered to satisfy the rigorous demands of global metal fabricators and OEM production facilities. The system combines a stress-relieved welded machine bed, dual-drive rack-and-pinion kinematics, and imported Japanese servo technology to deliver reliable motion accuracy and high processing dynamics. All machine configurations comply with European CE safety standards for industrial machinery.

Technical Features
Welded Machine Bed with Thermal Stress Relief
- Technical Issue: Continuous high-power laser operation and high-dynamic axis motion subject the machine frame to cyclic thermal and mechanical stresses, which can cause structural distortion over long operating cycles.
- Our Solution: The machine frame is fabricated from heavy-gauge steel plates and structural tubing. Following welding, the entire structure undergoes a 600°C furnace annealing heat treatment combined with vibration stress relief (VSR) to reduce residual mechanical stress in the weldments.
- Function: Residual stress reduction prevents long-term frame warping, maintaining structural alignment and linear guide parallelism under continuous industrial operation.
Drive Kinematics & Dynamic Response
- Challenge: Non-cutting motion, rapid traverse between profiles, and frequent direction changes on tight contours account for significant idle time in sheet metal processing.
- Our Solution: The motion system utilizes Japanese high-torque servo motors paired with precision helical rack-and-pinion dual drives on the main axes.
- Function: The drive system supports a maximum acceleration of 4G and a maximum rapid traverse speed of 100 m/min. Higher acceleration reduces cornering deceleration overhead and positioning time between cuts, improving cycle times particularly on thin-gauge components with high contour density.
Precision Axis Positioning and Repeatability
- Technical Issue: Downstream assembly, automated bending, and robotic welding require consistent part edge accuracy and tight dimensional tolerances.
- Engineering Solution: Axis motion is guided by precision linear rails and calibrated during assembly using optical alignment equipment and laser interferometers.
- Function: The sheet metal fiber laser cutting machine maintains an X/Y axis positioning accuracy of ±0.02 mm and a repeatability accuracy of ±0.02 mm, minimizing kerf variation and dimensional scrap across batch production runs.
Multiple fiber laser sources are available
- Technical Issue: Unplanned component failure or high electrical consumption increases total cost of ownership.
- Solution: Dongruitai Laser integrates solid-state fiber laser sources with power ratings ranging from 1.5 kW (1500 W) to 60 kW (60,000 W).
- Impact: Fiber laser diodes offer an expected operational lifespan of up to 100,000 hours under standard operating conditions. High electro-optical conversion efficiency lowers power consumption compared to traditional CO2 systems and supports compressed-air assist gas cutting options.
