Ball screw manufacturer Ball screw Miniature ball screws BALL SCREW MANUFACTURER NSK is proud to introduce the HMC Series ball screws for machine tools, featuring higher speed operation. Higher speeds are required not only by today’s machine tools industry, but also from the machine industry as a whole. NSK addresses these demands with a higher speed of 100 m/min. Sufficient measures are taken for improved durability, achieving a threefold improvement in rigidity and doubling load capacity. To guard against thermal expansion, a hollow shaft type is available which supports forced cooling for the shaft center. Use of this type provides even greater equalized accuracy and reduced warm-up time, helping to reduce costs. Vibration and noise control features reflect consideration of ergonomic and environmental concerns. We believe the HMC Series will play a major role in advancing the machine industry into a new era.
