Acra AM4 CNC VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a precision-engineered design suitable for general machining and fabrication work. The machine accommodates workpieces up to 990 pounds on a 54" × 10" work table, with an optional 90" width extension for larger components. The vertical spindle utilizes an ISO #40 taper configuration and delivers 3 horsepower at a maximum rotational speed of 4,200 RPM, providing adequate torque for moderate stock removal operations. The three-axis system provides 34 inches of longitudinal travel along the X-axis, 15 inches of cross-traverse along the Y-axis, and 5 inches of vertical quill movement along the Z-axis, enabling comprehensive workpiece positioning and manipulation. Manual tooling capability with single-tool capacity suits job-shop applications requiring frequent tool changes and setup flexibility. The machine's compact footprint and moderate spindle power make it ideal for tool and die work, prototype development, and small-to-medium production runs on materials including ferrous and non-ferrous alloys. The combination of manual tool handling and traditional spindle speed range positions this equipment as a reliable workhorse for skilled operators performing precision drilling, milling, and boring operations without requiring high-speed finishing capabilities.
