Acra B2 VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a **54" x 12" table** capable of supporting workpieces up to **1,000 lbs**, making it suitable for medium to large machining tasks. It has a **vertical spindle with an R-8 taper**, with the option for #30 taper, running up to **4,200 RPM standard** and optionally **5,000 RPM**, powered by a 3.0 HP motor rated for 30-minute duty cycles. The spindle design supports versatile tooling held manually in a single tool carrier, enabling precision control without automatic tool change. The machine operates on **three axes (X, Y, Z)** with travel distances of 30", 15.5", and 18" respectively, providing extensive working envelope for complex milling operations. Rapid traverse and max feed rates are available but unspecified, typical for manual feed systems. Optional support tables are available for enhanced stability during rotary or indexed operations. This setup is well suited for diverse milling applications including drilling, slotting, and contouring. The R-8 taper spindle is a widely accepted standard facilitating the use of common tooling with reliable precision. Overall, this machining center balances power, size, and precision for a variety of machining tasks where manual operation and robust workpiece capacity are essential.
