The NS Series actuator provides long stroke and speed nearly as fast as a linear.
The actuator structure is that rather than moving the nut in the straight line by rotating a ball screw, the ball screw is fixed and the nut is rotated by a servo motor built into the slider, so the slider moves in a straight line. Because the ball screw does not rotate, the influence of dangerous rotation speeds is minimal and this makes movement at high speeds possible even for long strokes.
A maximum speed of 2400 mm/s is attained through the use of high-lead precision screws (equivalent to C5). Also, since there is minimal impact from dangerous rotation speeds, movement is possible at the maximum 2400 mm/s even at the maximum stroke (3000 mm), so the cycle time can be greatly reduced.
The NS series combines nut rotation functions with the intermediate support structure that has proven itself in the ISA series to attain a 3000-mm stroke, stunning for a ball screw machine.
Two sliders are set on one shaft and a multi-slider is set to operate them separately. Since this makes it possible for two shafts to operate in the space of one shaft, it has a great effect in saving space and reducing tact time. The “collision prevention function” to prevent collisions between the sliders is standard equipment.
Using a servo motor and putting the motor on the outside of the ball screw eliminates the previous need for motor installation space and links the ball screw directly to further shorten the length even compared to the IS series which has already greatly reduced it.
A cable track that expands the capacity is available as an option.
