Why Complex Large Parts Demand a Rigid Structure Platform: GV1625 vs. Conventional龙门 Machines

In high-precision manufacturing, the choice of machine tool isn’t just about power—it’s about stability, repeatability, and long-term reliability. For industries producing complex large components like aerospace frames or composite molds, even minor vibrations can lead to costly errors. That’s where the GV1625 double-column CNC milling machine stands out—not as an upgrade, but as a necessary evolution.

The Hidden Cost of Weak Structural Design

Many manufacturers still rely on traditional gantry mills for large part machining. While initially affordable, these machines often suffer from:

• Low rigidity: Up to 30% more vibration under heavy cutting loads (based on internal testing across 120+ production lines).
• Thermal drift: Temperature changes cause up to 0.05mm deviation per hour—enough to fail tight tolerance specs in aerospace parts.
• Inconsistent surface finish: Poor stiffness leads to chatter marks, increasing rework rates by 15–25%.

GV1625: Engineered for Precision Under Pressure

The GV1625 isn’t just another CNC mill—it’s a purpose-built platform for complex, large-scale workpieces. Its dual-column structure, reinforced with cast iron and steel alloy beams, delivers:

• 2x higher static stiffness than standard gantry models (measured at 120 N/mm vs. 60 N/mm).
• Reduced thermal deformation through integrated heat dissipation channels—maintaining ±0.02mm accuracy over 8-hour shifts.
• Optimized force transmission that minimizes deflection during deep cuts, ensuring consistent tool life and surface quality.

“After switching to GV1625, our mold production time dropped by 22%, and scrap rate fell from 7% to under 2%. It’s not just faster—it’s smarter.”

Real Results, Real ROI

In one case study involving a leading aircraft component supplier, GV1625 enabled the machining of a 2.5m-long carbon fiber layup mold with:

• Surface roughness improved from Ra 6.3μm to Ra 1.2μm — critical for composites bonding.
• First-pass yield increased from 82% to 96% due to reduced vibration-induced warping.
• Tool wear decreased by 35% thanks to optimized chip evacuation and stable cutting forces.

For decision-makers evaluating equipment investments, the question isn’t whether you can afford the GV1625—it’s whether you can afford not to have it.
