Acra AM3 VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a 54" x 10" manual table capable of supporting up to 750 lbs, designed for robust workpiece handling. It operates on 3 axes (X: 39.5", Y: 16.5", Z: 16") with precise travel and rapid traverse capabilities, delivering versatile machining within these travel limits. The spindle is vertically oriented with an R8 taper, standard for manual tooling, offering a top speed of 5,440 RPM and an optional 4,200 RPM variant. The motor power rating is 2 HP continuous (30-minute rating) with an option for 3 HP for enhanced performance. The tool carrier supports a single tool with manual tool changes and zero tool change chip time, emphasizing manual operation rather than automated tool changing. The spindle taper conforms to the R8 specification, widely recognized for a taper angle of approximately 16.26 degrees and typically used on manual vertical mills; it allows secure tool holding with drawbar retention. This machine lacks rotary and U-axis support and an index table as an option, focusing on essential three-axis machining functions. Its rigid, stable structure supports precise machining tasks requiring vertical spindle orientation, suitable for milling, drilling, and tapping operations. The combination of manual tool handling, three-axis travel, and a moderate horsepower spindle makes this vertical mill ideal for workshop environments where flexibility and manual control are prioritized.
