2012 HAAS MINI MILL VERTICAL MACHINING CENTERS

Technical Description

The 2012 Haas Mini Mill is a 3-axis vertical machining center designed for small-part production, prototype machining, and light-duty milling and drilling operations. The Mini Mill is one of Haas's most enduring and widely adopted platforms, recognized for its compact footprint, straightforward operation, and low entry cost relative to full-size VMCs. Axis travels measure 16 in. in X, 12 in. in Y, and 10 in. in Z, providing a practical working envelope for small-to-medium components. The 18 x 16 in. worktable features T-slots for flexible workholding and accommodates standard vises, fixture plates, and tombstones. The spindle is rated at 7.5 HP continuous and reaches 7,500 RPM (with 10,000 RPM optional spindle available) on a CAT40 taper interface, suitable for a wide range of materials including aluminum, steel, brass, and engineering plastics. Rigid tapping is standard, eliminating the need for floating tap holders and improving cycle time consistency. The umbrella-style automatic tool changer provides reliable tool exchange in production sequences. Coolant delivery and chip management are integrated into the machine base for clean, efficient operation. The Haas CNC handles programming and machine management via a color display with conversational prompting, full G-code support, and macro capability. The Mini Mill's installed weight of approximately 2,900 lbs allows it to be positioned in shops with limited floor-load capacity, making it a practical choice for training environments, R&D cells, and low-volume production of precision small parts.
