FIVES GIDDINGS & LEWIS VTC 3500 VERTICAL MACHINING CENTER

Technical Description

This CNC vertical machining center features a main spindle with a maximum turning diameter and swing of 145.000", accommodating large workpieces up to a turning length of 68.900". The main spindle chuck diameter measures 137.000", supporting robust holding capacity. It delivers 100 HP with a maximum spindle speed of 150 RPM, optimized for heavy-duty turning operations. The rotary tool offers 44.20 HP and can reach speeds up to 4,000 RPM, enabling versatile milling or drilling tasks. The machine supports up to 26 tools with an optional simultaneous use of 2 cutting tools, facilitating complex machining operations. With 2 axes, the vertical machining center provides X-axis travel of 80.700" and an optional Z-axis travel extension up to 68.890", allowing precise control over part dimensions. The Y-axis is specified with rapid traverse at 787 inches per minute (ipm), matching the rapid traverse rates for fast tool repositioning on the machine. This configuration is ideal for machining large, heavy workpieces while maintaining high repeatability and precision. The 2-axis control focuses on diameter (X-axis) and length (Z-axis) adjustments, suitable for symmetrical turning jobs with optional off-center capabilities via the Y-axis. The machine’s powerful spindle horsepower, large chuck capacity, and extensive travel ranges support production of sizable cylindrical components common in heavy industries. The combination of high torque at low RPM and rapid tool change capabilities optimizes cycle times and part quality across various cutting applications. This vertical machining center is suited for demanding manufacturing environments requiring precision, flexibility, and efficiency in large-part turning.
