Our Precision Spinning top is made with an exceptional precision-- we don't allow deviations of roundness or coaxiality even by a few microns. Furthermore, NEXT-URANUS is made by carving out from a stainless steel bar (SUS303) by using a Precision CNC lathe, a machine that is also used for processing watches. By processing with one-chucking, we raised coaxiality of the Spinning top to the highest level possible. In addition, even on the processing of the tip of Spinning top, where the peripheral speed becomes zero while spinning, we have created the shape of the sphere R 0.3mm(0.118inches) by using our unique technique. After the precession movement, Spinning top's spinning becomes stable. During the stable period, the Spinning top spins extremely stably as if it is pausing and standing; you will never get tired of watching this smooth movement.
Please note that if you drop or hit the product against the ground, the tip of Spinning top may break and lose its balance.
