Acra B3 VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a 54" x 12" worktable supporting workpieces up to 1,000 lbs, suitable for a variety of medium to large parts. The machine operates with a manual tool carrier holding one tool, complementing its single spindle design with a vertical NT #40 taper spindle. The spindle delivers 5 HP continuous power (30-minute rating) with a top speed of 3,750 RPM, optionally upgradable to 5,000 RPM, allowing effective machining of various materials. The 3-axis configuration includes travels of 30" on the X-axis, 15.5" on the Y-axis, and 18" on the Z-axis, providing substantial workspace for complex machining tasks. Rapid feed rates and precise linear motion control enable efficient and accurate positioning along all axes. Optional support for rotary or indexing tables enhances versatility for advanced machining operations requiring multi-angle workpiece orientation. The machine’s structure and vertical spindle orientation deliver high rigidity and stability, essential for consistency during heavy-duty milling, drilling, tapping, and boring processes. This setup makes it well-suited for applications demanding high precision, moderate to heavy cutting loads, and reliable manual tool handling on a robust and stable platform.
