KOMATSU NTC N4Q HORIZONTAL MACHINING CENTER

The Komatsu NTC N4Q is a high-speed horizontal machining center designed for precision machining of die cast aluminum, steel castings, and other materials used in automotive, medical, optical, and aerospace industries. It features a 3-axis traveling structure with a fixed 19.68" x 19.68" table, supporting a standard rotary table with optional indexing. The spindle is horizontal with a CAT-40 taper, delivering up to 12,000 RPM and 25 HP (30-minute rating), optimized for high-speed cutting and rapid spindle acceleration in 1.2 seconds. The machine utilizes an Automatic Tool Changer (ATC) with a twin-arm arm mechanism capable of handling up to 32 tools with a fast 3.9-second tool change time. It includes a two-pallet changer system for efficient workflow and supports rapid feed and traverse rates of 2,362 inches/minute across X (25"), Y (19.68"), and Z (19.68") axes. The machine incorporates coolant-through-spindle technology and center-through cooling for the X-axis ball screw to maintain thermal stability and high accuracy. Heavy-duty axis drives combined with zero-clearance, low-resistance linear guides ensure precision and durability during rapid movements. The design supports standalone use or integration into flexible transfer lines with hydraulic quick-fixture connections at the pallets. This model is suited for industries requiring high productivity and accuracy in complex, high-speed horizontal machining applications.
