Acra AM3 CNC VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a robust table measuring 54.000 inches in length by 10.000 inches in width, capable of supporting workpieces up to 990 lbs. The spindle is oriented vertically and equipped with an R-8 taper, with an optional #30 taper for added versatility. The spindle delivers a maximum speed of 4,200 RPM and is powered by a 3.0 HP motor (30-minute rating), ensuring reliable performance for a range of milling tasks. Tooling is managed manually, with a single tool holder and no automatic tool changer. The machine operates on three axes (X, Y, Z), each providing precise travel: X-axis up to 39.500 inches, Y-axis up to 16.000 inches, and Z-axis up to 16.000 inches. The design supports accurate positioning and controlled feed rates, suitable for detailed machining operations. The absence of a U-axis indicates a standard configuration for conventional milling applications. The machine’s construction emphasizes rigidity and stability, making it well-suited for both prototyping and production environments where precision and durability are essential.
