SHANGHAI SIGMA VMC1890 VERTICAL MACHINING CENTER

Technical Description

The SHANGHAI SIGMA VMC1890 Vertical Machining Center is a robust 3-axis CNC milling machine designed for heavy-duty precision machining. It features a large travel capacity of 70.87 inches on the X-axis, 35.43 inches on the Y-axis, and 27.56 inches on the Z-axis, accommodating workpieces of significant size and complexity. The machine is equipped with a powerful 29.5 hp spindle motor capable of speeds up to 6,000 RPM, utilizing a BT-50 taper for enhanced rigidity and tool holding capacity. Its worktable measures 78.74 inches in length and 35.43 inches in width, supporting a variety of workpieces. The tool magazine accommodates 24 tools, facilitating extended unmanned machining cycles and rapid tool changes. The VMC1890 operates under the FANUC 0i-MATE-MD CNC control system, which offers precise digital servo control, linear and circular interpolation, and extensive programming capabilities for complex machining tasks. This control supports fine acceleration/deceleration management, multi-axis coordination, and high-speed serial communication for optimized machining performance. The machine's structural components—consisting of high-strength cast iron with ribbed casting—provide high stability and vibration resistance, contributing to accuracy and surface finish quality. Its rapid traverse rates typically reach up to 15 m/min on the X and Y axes and 12 m/min on the Z axis, ensuring efficient material removal and cycle times. Suitable for aerospace, automotive, mold, and general mechanical manufacturing, the VMC1890 combines rigidity, precision, and automation capabilities for high-efficiency machining on large workpieces.
