PAT MOONEY PMI-CNC 300A VERTICAL MACHINING CENTER

Technical Description

The PMI-CNC 300A is a 3-axis vertical machining center designed for precision milling, drilling, and tapping operations on aluminum and non-ferrous materials including copper, brass, and plastics. The machine features an impressive X-axis working length of 118 inches (3000mm), with Y and Z-axis travel of 11.81 inches (300mm) each, making it ideal for processing long profiles and extrusions. Equipped with a 7.5 HP spindle motor capable of 20,000 RPM, the machine delivers robust cutting performance suitable for aerospace, automotive, door and window, and architectural applications. The traveling column design incorporates servo motors (Mitsubishi) combined with precision ball screw and gear/rack transmission for accurate positioning on all three axes, with rapid traverse rates of 328 FPM on the X-axis and 98.4 FPM on Y and Z axes. The cutting feed rate ranges from 0.0393 to 39.37 inches per minute, providing flexibility for various materials and operations. Standard equipment includes an ER32 tool holder with air clamps, automatic waylube lubrication system, and oil misting cooling to extend tool life and ensure superior cut quality. The machine is equipped with precision linear guide ways for smooth movements, a safety guard, light curtain, full spindle cover, and spindle air blast as standard features. The table working surface measures 11.81 x 118 inches with four vises, each providing 242 lbs maximum holding power. PC CNC control enables straightforward operation, while the compact footprint and comprehensive safety features make it suitable for job shops and production environments requiring reliable, consistent machining capabilities.
