Acra AM2 CNC VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a robust work table measuring 42" x 9", with an optional extended length of 49" x 9", capable of supporting workpieces up to 550 lbs. It is equipped with a vertical spindle utilizing an R8 taper, with an optional #30 taper, designed to operate at speeds up to 4,200 RPM driven by a 3.0 HP motor rated for 30-minute duty cycles. The tooling system includes a manual tool carrier holding a single tool with zero tool change chip time. It operates across three axes (X, Y, Z) with travels of 26" (optionally 33") longitudinally, 12" laterally, and 5" vertically. The machine's spindle taper conforms to the R8 standard, which typically has a taper angle of approximately 16.26 degrees and is widely used for precision tool holding via drawbar clamping, ensuring secure and accurate machining. This vertical mill is designed for versatility in single-sided milling and drilling operations, suited for moderate workpiece sizes and weights, with manual tool changes and moderate spindle speed suitable for diverse machining tasks. The axis feed and travel specifications allow for precise material removal on the X, Y, and Z axes, supporting a range of medium-duty milling applications. Its simple tooling and spindle design reflect traditional vertical knee mill characteristics, optimized for manual operation and accurate machining on smaller to mid-sized workpieces.
