KOMATSU NTC NH3S HORIZONTAL MACHINING CENTER

Technical Description

The Komatsu NTC NH3S Horizontal Machining Center is a high-performance CNC machine designed for precision and efficiency in demanding production environments. It features a robust 14.0" x 12.0" table, with an optional extended table size of 20.0" x 12.0" to accommodate larger workpieces, supporting a maximum workpiece weight of 1,100 lbs. The machine is equipped with a horizontal spindle featuring a #40 taper and a maximum spindle speed of 12,000 rpm, delivering 5.0 HP (30-minute rating) for reliable cutting power. The NH3S offers a standard 3-axis configuration, with an optional 4th axis for enhanced versatility. Axis travels are 13.8" (X), 11.0" (Y), and 13.8" (Z), with optional X-axis travel extending to 19.7". The machine supports both index and rotary tables as optional features, enabling complex multi-sided machining. Rapid traverse rates reach 1,970 ipm on all linear axes, while the maximum feed rate is 394 ipm, ensuring fast cycle times and high productivity. The A-axis provides 105° of rotation, and the B-axis offers full 360° indexing for flexible part positioning. Tool change chip-to-chip time is not specified, but the machine supports optional pallet changers for increased automation. With its compact footprint, high-speed performance, and flexible configuration options, the NH3S is ideal for high-precision, medium to large part machining in industries such as aerospace, automotive, and general manufacturing.
