G4020X sheet fiber laser cutting machines
G4020X is an HSG GX-family sheet laser cutter. The documented processing format is 4064 × 2040 mm; the table distinguishes model dimensions from family-level control features.
Configuration context
The G4020X record keeps its processing format and laser-power range separate from features shared by the GX family. Alpha T control, nesting and dynamic gas-pressure functions belong to the family description; the quotation should identify the installed options.
Selection questions
Specify sheet size, material, thickness, assist gas and required cut quality. Positioning accuracy is not a finished-part tolerance or a cutting-thickness guarantee.
