G Series Side-Load Laser Tube Cutting Systems

Type: Product Series Entity | Source: QG Laser Technical Proposals

Overview

The G Series is the backbone of QG Laser. Side-loading architecture spanning four sub-series: Standard (C), Zero Tailing (CL), 5-Axis Bevel (K), and Straight Cut (Z). Diameters from 90mm to 350mm. Power from 3000W to 6000W. Automation from manual to fully autonomous. Every G Series machine shares one philosophy: cut more. waste less. repeat forever.

Model Naming

``


G{MaxDiameter(mm)}{Variant}{-Sub}

 G     = High-Speed
 120   = 120mm max tube diameter
 C     = Side-Load
 CL    = Side-Load with Zero Tailing (L)
 K     = Bevel — no C suffix, architecture independent
 Z     = Straight Cut, small dual-chuck push-load reciprocating feed
 V12   = Next-gen V12 platform
 MAX   = Upgraded heavy-duty

 G120C     = High-Speed 120 Side-Load Standard
 G120CL    = High-Speed 120 Side-Load Zero Tailing — 99% utilization, <20mm remnant
 G120K     = High-Speed 120 Bevel — ±45°, one-pass weld-ready
 G90Z      = High-Speed 90 Straight Cut — dual-chuck push-load reciprocating
 G120C-V12 = High-Speed 120 Side-Load Next-Gen V12 — dual control system
 G240C-MAX = High-Speed 240 Side-Load Upgraded — reinforced architecture
