BOCHI VMC850G VERTICAL MACHINING CENTER

Technical Description

The BOCHI VMC850G is a precision vertical machining center engineered for comprehensive CNC milling operations across mold manufacturing and mechanical processing applications. This three-axis machine delivers X, Y, and Z-axis travels of 800mm, 550mm, and 550mm respectively, accommodating workpieces up to 1000×550mm on its robust worktable with a maximum load capacity of 600kg. The VMC850G features a BT40 spindle taper with spindle speeds ranging from 40–12,000 rpm, powered by a 7.5kW main motor. Rapid traverse rates of 24/24/20 m/min (with optional 48/48/36 m/min) enable efficient stock removal, while positioning accuracy of ±0.003mm per 300mm and repeatability of ±0.002mm ensure precision finishing. The machine utilizes Taiwan-specification linear guide rails and ball screws, delivering cutting feed speeds from 1–8,000 mm/min. Standard equipment includes a 24-position automatic tool changer with 3.5-second tool change time, accommodating tools up to 120mm diameter and 8kg weight. The machine's triangular rib column structure and ultra-wide base foundation provide exceptional rigidity and thermal stability for demanding applications. Optional features include fourth and fifth-axis rotary tables, automatic tool length measurement systems, probes, and chip removal equipment. Weighing 6,700kg with overall dimensions of 2650×2400×2900mm, the VMC850G integrates FANUC or Mitsubishi CNC control systems and incorporates an automatic cyclic lubrication system. This configuration makes it suitable for complex mold cavity work, 3C products, automotive, aerospace, and instrumentation component processing.
