Engineering Overview & Structural Rigidity
The Qingluan VMC850 Vertical Machining Center represents the pinnacle of mid-size industrial milling performance. Engineered around an ultra-rigid HT300 Meehanite cast-iron foundation that undergoes dual thermal stress-relief cycles, the VMC850 eliminates structural deformation under heavy cutting loads.
With an expansive 800 × 500 × 500 mm working envelope and a 1000 × 500 mm ground T-slot worktable capable of handling 600 kg workpieces, this machining center easily accommodates high-precision automotive components, aerospace brackets, plastic injection mold bases, and complex mechanical prototypes.
Core Technical Advantages
- High-Dynamic Direct-Drive / Belt-Drive Spindle: Powered by a 7.5 kW continuous / 11 kW peak high-torque spindle motor reaching 8,000 or 10,000 RPM, dynamically balanced to ISO G0.4 standards to eliminate surface chatter and maximize carbide end-mill life.
- Pre-tensioned C3 Precision Ball Screws: Double-nut ball screws on all three axes are laser-calibrated using Renishaw interferometers with pitch-error and backlash compensation, guaranteeing ±0.005 mm positioning and ±0.003 mm repeatability.
- Rapid 24-Pocket Disc ATC: Bi-directional random tool selection driven by a high-precision mechanical cam mechanism ensures smooth, vibration-free 1.8-second tool-to-tool changeover.
- Ergonomic Full Enclosure & Chip Management: Sealed telescopic stainless-steel way covers protect guide surfaces from abrasive swarf, paired with high-flow dual flush nozzles and an automatic screw/hinge chip conveyor.
