Heavy-Duty Structural Rigidity for Tough Metal Cutting
The Qingluan VMC855 Vertical Machining Center is built for heavy metal removal in tough materials such as pre-hardened tool steel (P20, H13), stainless steel (304, 316L), and ductile iron. By widening the Y-axis stroke to 550 mm and deploying heavy-duty 45 mm roller linear guideways, the VMC855 provides over 35% higher structural torsional resistance compared to standard 850-size machines.
Core Technical Advantages
- Widened Column & Pyramidal Bed Architecture: Symmetrically ribbed box castings absorb aggressive cutting chatter, allowing large-diameter face mills and high-feed indexable cutters to run at maximum material removal rates (MRR).
- Dual Support Spindle Headstock: High-precision angular contact bearings with circulating oil chillers ensure thermal stability under continuous heavy roughing and prolonged finish-milling cycles.
- Ready for 4th-Axis Rotary Indexing: Spacious table envelope with 800 kg load capacity seamlessly integrates pneumatic or hydraulic 4th-axis direct-drive rotary tables for multi-sided turbine blade and complex valve housing machining.
