NSK utilized the 2017 EMO show in Hanover, Germany as the launch platform for a number of innovations designed to enhance machine tool performance. Among them is the new generation of DIN-standard ball screws. The high-speed and low-noise ball screw not only overcomes the challenges of European machine tool applications but also complies with DIN 69051 (ISO 3408) of dimensional and tolerance requirements.
Manufactured with shaft diameters from 32 to 63 mm and leads from 10 to 40 mm, the new ball screw for European machine tools offers a speed factor of 160,000 dn. This level of performance allows them to function in high-speed machining applications that require precise positioning.
Its smooth operation also sets a new standard in optimal preconditioning to withstand as little vibration as possible in linear systems, while also reducing noise levels. Among the factors contributing to this feature was the ball deflector that was further developed to accommodate the new product line.
NSK has been developing ball screws for machine tools since 1960. Today, the product portfolio is very diverse, offering shaft diameters from 4 to 200 mm, suitable for a wide variety of specific requirements such as extremely low noise, short strokes and maximum positioning accuracy.
