Pinnacle LV137/147 VERTICAL MACHINING CENTER

Technical Description

The Pinnacle LV137/147 Vertical Machining Center is a high-precision CNC machining tool designed for medium to large workpieces with a table size of 59.0" x 27.55" (optionally 63.0" x 27.55") supporting a maximum workpiece weight of 2,640 lbs. It features a vertical spindle with a BIG-50 taper, capable of 6,000 RPM standard and an optional increase to 8,000 RPM. The spindle is powered by a 20 HP motor rated for a 30-minute duty cycle, ensuring robust machining performance. The machine operates on three axes (X, Y, Z) with travels of 51.18" (optional 55.11") in X, 27.95" in Y, and 24.01" in Z, each axis supporting a rapid traverse rate of 1,181 inches per minute and a maximum feed rate of 394 ipm. The tool handling system includes an automatic tool changer (ATC) with a standard capacity of 24 tools, expandable to 32 tools, and offers an optional pallet changer with two pallets for increased productivity. Linear guideways on all axes reduce friction, enhancing accuracy and repeatability. The machine lacks a U-axis and rotary or index tables, focusing on rigid three-axis milling operations. Its design supports heavy-duty machining of metals such as steel and aluminum with precision, leveraging features like a circulating oil cooling spindle system to minimize thermal deformation. Control options include Fanuc or Mitsubishi CNC systems, with a human-friendly interface to optimize operation. Overall, this center is suited for workshops requiring reliable, accurate milling with substantial workpiece capacity and tooling flexibility.
