MAKINO A51NX PRO 6 HORIZONTAL MACHINING CENTER

Technical Description

The Makino A51NX PRO 6 is a precision horizontal machining center featuring a 15.75" x 15.75" standard support index table capable of handling workpieces up to 880 lbs. It is equipped with a #40 spindle taper running at speeds up to 14,000 RPM, with an optional upgrade to 20,000 RPM, delivering high torque for robust machining performance, especially on ferrous materials. The machine provides three axes of travel (X: 22.0", Y: 25.2", Z: 25.2") with a maximum feed rate of 1,968 inches per minute and rapid traverse up to 2,362 inches per minute for efficient material removal and quick positioning. Tool management is handled by an automatic tool changer (ATC) with a standard capacity of 60 tools, expandable up to 313, and rapid tool change times of 0.90 seconds (tool-to-tool) and 2.20 seconds (chip-to-chip). The machine includes a standard pallet changer with two pallets, optimizing workflow for high-volume or complex part production. Notable features include a rigid 3-axis configuration, option for a 4th axis, high-speed spindle with advanced torque control, dual-supported tool-change arm, and a one-piece way cover design that enhances durability and reliability. The A51NX PRO 6's combination of high power spindle, robust mechanical design, and advanced tool handling enables high-precision, high-volume machining in demanding industrial environments.
