Haas Automation, Inc. MINI MILL VERTICAL MACHINING CENTER

Technical Description

The Haas Mini Mill is a compact 3-axis vertical machining center engineered for precision work in space-constrained environments. Featuring a 28.75" x 12" work table with a maximum workpiece capacity of 500 lbs, this machine delivers full-size machining performance in a small footprint. The vertically-oriented CAT-40 spindle operates at 6,000 RPM with a 7.5 HP motor rated for 30-minute continuous duty, providing adequate power for both light finishing and moderate production cuts. The machine features three linear axes—X, Y, and Z—with travels of 16", 12", and 10" respectively, enabling versatile part geometry and positioning capabilities. Rapid traverse rates reach 600 inches per minute across all axes, while cutting feed rates maximum out at 500 inches per minute, ensuring efficient cycle times and smooth tool paths. The 10-position automatic tool changer delivers rapid tool changes in 4.2 seconds chip-to-chip, minimizing non-cutting time and maximizing productivity. The machine is controlled by Haas CNC technology, supporting advanced features including rigid tapping, DNC capabilities, and macro programming to accommodate diverse manufacturing requirements. Constructed with a reinforced cast-iron base and column design, the Mini Mill maintains rigidity and stability during machining operations while operating on standard 230-volt, 3-phase electrical service. This machine represents an ideal platform for job shops, educational institutions, and small manufacturers requiring reliable, efficient vertical machining in applications where floor space is limited.
