Linear guides play an irreplaceable role in machine tool motion because they serve as the primary driving component. This gives linear guides considerable room for development. The demands of high spindle speeds and rapid acceleration/deceleration in machine tools often lead to increased loads on ball screws. To meet these high-speed requirements, it is generally possible to use ball screws with large lead pitches. However, selecting ball screws with large lead pitches can result in insufficient load-carrying capacity and rigidity. The high-speed ball screws developed by HIWIN feature low noise and low vibration, making linear guides an exceptional choice for machine tool components. As a result, linear guides also help mitigate the drawbacks associated with ball screws.

Anti-vibration application of linear guides on machine tools:
As is well known, excessive vibration amplitude in machine tools can significantly shorten their service life. Therefore, effectively controlling the vibration amplitude of machine tools can greatly benefit their performance. In this regard, linear guideways play a crucial role. To meet the high demands of industrialization in the machine-tool industry, the industry is increasingly adopting rolling-element guidance systems such as linear ball guides, which have enabled traditional feed rates of just a few meters per minute to be boosted to over ten or even dozens of meters per minute. This represents a substantial improvement in efficiency. The adoption of linear guideways has dramatically enhanced machine-tool productivity, a development closely linked to ball screws. During their effective service life, these machine tools can operate continuously with virtually no maintenance required—a truly win-win situation.
Machine tools must have high vibration resistance: Machine tools equipped with linear guides are prone to vibration, and the rapid reciprocating motion of moving parts can exert significant impact on the machine bed. Linear rolling guide pairs have extremely low damping, greatly enhancing the overall vibration resistance of the machine tool.
