Analyzing problems and finding the right solution is one of Ball screw manufacturer NSK’s specialties. When a medical manufacturer needed to correct inaccuracies they were experiencing on reagent testing machine (liquid handler), they called on NSK. Our engineers determined that placement inaccuracy was caused because machine was using a low-torque motor with high-torque linear guide from a competitor. NSK Engineering advised that a linear guide designed with the ability to handle the low torque motor would solve the problem. The competitor’s product was removed and replaced with NSK’s PU and PE series linear guides.
NSK breaks through to an unprecedented high speed of 100 m/min. Even at such speeds, NSK ball Screws maintain a high degree of accuracy with the lower noise and compact design identified with NSK.
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.
