High-Precision Laser Cutting Machine GL3015-SJ | 500W-3000W | Trusted China Suppliers and Factory
Product Features
This robust and highly optimized mechanical structural design achieves outstanding overall rigidity and structural stability. By virtue of its superior stiffness performance, the equipment is capable of reliably sustaining dynamic loads generated under extreme operating conditions, steadily enduring high acceleration levels up to 1.5 G during frequent rapid positioning strokes and continuous high‑speed feeding motions. Meanwhile, the well‑engineered structure effectively restrains mechanical vibration, elastic deformation and resonance interference induced by high dynamic movement, thereby minimizing machining errors caused by structural displacement. As a result, it maintains consistently precise dimensional accuracy, stable repeat positioning accuracy and excellent workpiece surface finish quality throughout the entire continuous machining process, significantly improving processing reliability, production efficiency and finished product qualification rate in high‑speed precision manufacturing scenarios.
The main bed applies a heavy-duty integral frame with precisely computer-controlled welding to guarantee uniform strength and tight structural connection. Before precision finishing, the whole structure is processed by advanced vibration stress relief technology, reducing residual stress by over 80% compared with traditional methods. All guide rail mounting surfaces are finished by large gantry milling, achieving a smooth surface quality of Ra1.6μm. This provides an ultra-flat foundation for linear guides, minimizing friction resistance and ensuring stable motion accuracy, high processing efficiency and extended service life in long-term mass production.

The GL3015-SJ offers a cutting range of 1500mm × 3000mm, making it suitable for large-format workpieces. The power range spans from 500W to 3000W, providing flexibility for cutting a wide variety of materials at different thicknesses and speeds.
Q
What level of positioning accuracy does this machine achieve?
The GL3015-SJ achieves both positioning accuracy and repeated positioning accuracy of ±0.03mm/m. This high level of precision is supported by the ultra-flat guide rail mounting surfaces finished to Ra1.6μm, high-precision grinding helical rack and pinion transmission, and precision planetary reduction gears.
Q
What key components and brands are used in the drive and electrical systems?
The machine uses a Bus AC servo drive system. The X and Y axis linear guides are sourced from Shanghai Silver or CSK, while the rack uses M2/M3 specifications. The gas path and proportional valves are SMC brand, and all electrical accessories are Schneider, ensuring reliable performance and easy global maintenance support.
Q
Can the workbench configuration be customized, and what power supply is required?
Yes, the GL3015-SJ comes standard with a single workbench, but a double exchange platform can be configured according to customer demand for improved production efficiency. The machine requires a 380V 50Hz/60Hz power supply and has a footprint of 5000mm × 2600mm × 2000mm, suitable for standard industrial facilities.
