SHAN WANNAN VMC855 VERTICAL MACHINING CENTER

Technical Description

The SHAN WANNAN VMC855 is a precision vertical machining center designed for high-accuracy industrial applications. This three-axis CNC machine features a robust worktable measuring 1000×550mm (39.37×21.65 inches) with a maximum load capacity of 500-600kg, accommodating diverse workpiece sizes and weights. The machine delivers impressive travel ranges across all axes: 800mm (33.46 inches) on the X-axis, 550mm (21.65 inches) on the Y-axis, and 550mm (25.59 inches) on the Z-axis, providing substantial machining envelope for complex part production. Powered by a 11-15kW spindle motor (approximately 20.1 hp) with a BT40 taper, the VMC855 achieves a maximum spindle speed of 8,000 RPM, enabling efficient material removal across various applications. The machine incorporates rapid traverse rates of up to 48m/min on X and Y axes and 36m/min on the Z-axis, significantly reducing cycle times. Positioning accuracy of ±0.005mm and repeat accuracy of ±0.003mm ensure consistent, high-precision machining suitable for automotive, aerospace, and mold manufacturing industries. The VMC855 features an automatic 24-station disc-type tool changer with rapid tool-to-tool changeover times of approximately 1.5 seconds, maximizing productivity. Advanced components include Taiwan-sourced spindles, precision ball screws, Japanese NSK bearings, and a comprehensive automatic lubrication system. The machine weighs approximately 5,000-5,500kg and measures 2,800×2,300×2,300mm, offering a compact footprint with substantial work capacity ideal for precision manufacturing operations.
