When selecting fabrication machinery (such as CNC fiber laser cutters, press brakes, or welding robots), you must prioritize positioning accuracy (typically ±0.03mm or better) and repeatability. For cutting equipment, verify the laser source brand (e.g., IPG, Raycus) and the power output (kW) relative to your material thickness. For hydraulic machinery, ensure the system pressure stability and the quality of PLC control systems (e.g., Siemens, Schneider) to guarantee long-term operational reliability.
