Komatsu NTC N4Q

NTC Horizontal Machining Center Model N4Q - 500 Suitable for high speed machining of die cast aluminum parts, as well as near net shape, or precision steel castings for the automobile industry, office automation, medical, optical and aircraft industries. Utilizes a three axis traveling structure with a fixed table that allows the machine to be used as a stand alone universal machine, or in flexible transfer lines. 180-degree rotary type high speed APC equipped with a 90-degree 4th axis NC turn table at the loading pallet. Hydraulic source can be easily provided for each pallet, for quick connection to hydraulic fixtures. To assist high speed machining, coolant through the spindle is provided as a standard feature. X axis ball screw with center through cooling coolant as standard feature helps p revent heat distortion and maintain high accuracy. A 12,000 RPM wide range, the 25 horsepower spindle motor provides optimum speed for high speed machining. Spindle start time (0~12,000) has been reduced to only 1.2 seconds respectively. Quick response, heavy duty axis drives and zero clearance, as well as no resistance linear motion guide way systems, allow all 3-axes feed rates and rapid traverse rates of 2,362.2 inches per minute. Feeds and travels such as these are required for optimum metal removal on near net shape and non-ferrous parts. 3.9 second chip-to-chip automatic tool change times get the cutters to the work piece in the shortest time to allow minimum out-of-cut non-productive time. The new 180 degree rotary pallet changer moves the pallet from the load station to the action station in only 7.4 seconds, again minimizing the out-of-cut time. The loading station also rotates to allow access to all sides of the pallet to expedite loading and unloading. The standard 0.001 degree table index time for a 90 degree index has been reduced to only 2.0 seconds.
