Komatsu NTC N3Q

NTC Horizontal Machining Center Model N3Q 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. It 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. As a stand-alone machine it has a 180-degree rotary type high-speed APC equipped with a 90 degree 4th axis NC turn table at the loading pallet. In accordance with the high speed and high productivity features, a 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. A 12,000 RPM wide range, 5 horsepower spindle motor provides optimum speed for high speed machining. Spindle bearing ID realizes a large size of 1.97" with high rigidity. Quick response, heavy duty axis drives and zero clearance, no resistance linear motion guide way systems, allow all 3-axes feed rates and rapid traverse rates of 1,970 inches per minute. Feeds and travels such as these are required for optimum metal removal on near net shape and non-ferrous parts. 4.0 second chip-to-chip arm-less automatic tool change times get the cutters to the workpiece 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 6.9 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. The hydraulic, pneumatic and lubrication controls are collectively arranged in the back to realize space saving and efficient maintenance work.
