SPN Series - the performance models from Niigata. The inventor of the BOX-in-BOX design now introduces the third generation of the SPN Series. Since 1993, these models have been recognized worldwide as leading machines in terms of productivity and added value. Horizontal high-performance machining centres with pallet sizes from 500x500 mm to 800x800 mm. THE BOX IN BOX PRINCIPLE The spindle is supported in a nodular cast iron carriage running on vertical and widely spaced X-axis guides. Even under dynamic load, there is minimal deflection at the base and column. Reduced mass for easier acceleration/deceleration and longer life and less maintenance. Axial pressure is always absorbed between the upper and lower X-axis guideways. The center of gravity of the spindle and spindle slide is directly above the lower X-axis guideway, which is located in the Z/X plane. Translated with DeepL
