PINNACLE LH500 HORIZONTAL MACHINING CENTER

Technical Description

The Pinnacle LH500 Horizontal Machining Center is a robust 4-axis CNC machine designed for high-precision horizontal machining. It features a **19.7" x 19.7" (500mm x 500mm) table** capable of supporting workpieces up to **880 lbs (400 kg)**. The machine is equipped with a **horizontal spindle** featuring an ISO 40 taper, capable of speeds up to **8,000 RPM** with an optional upgrade to **15,000 RPM**, powered by a 20 HP spindle motor rated for 30 minutes. Its tool handling utilizes a **40-tool chain-type automatic tool changer (ATC)** as standard, with an optional pallet changer supporting up to 2 pallets for enhanced productivity. The LH500’s travel distances are **25.59" (X), 22.04" (Y), and 22.04" (Z)** with rapid traverse rates to 1,181 IPM, providing efficient multi-axis movement with a full 360° B-axis rotation for complex part machining. The horizontal orientation combined with a rigid fixed-column structure optimizes stability and precision, while the rotary table offers hydraulic-expansion locking for heavy cutting resistance and consistent positional accuracy. The machine is compact relative to competitors, featuring advanced linear guideways and a sturdy fabricated base to minimize deformation over time. It supports a workpiece size up to approximately 630 mm diameter by 610 mm height and includes optional features such as pallet changers and enhanced spindle speeds, suitable for versatile manufacturing applications requiring precision and efficiency in horizontal machining environments.
