Application:
The Samchully STA Series Self-Centering Steady Rests are designed for CNC lathes and turning centers that require stable support when machining long bars, pipes, or slender workpieces. Ideal for both fixed and travelling applications, the STA Series ensures precise centering and vibration control during roughing and finishing operations. These steady rests are especially effective in applications where maintaining concentricity, surface finish, and machining accuracy is critical.
Product Features:
The STA series features a self-centering mechanical design where the arms and center rollers are interconnected, allowing them to automatically adjust to varying workpiece diameters within a centering range from 6mm to 50mm. Central lubrication ensures smooth operation and reduced wear, while the spring-free mechanical system improves durability and long-term reliability. Each roller delivers consistent clamping force, with maximum clamping capacity ranging up from 100kgf to 3000kgf per roller. Designed for demanding production environments, the STA Series supports high roller surface speeds ranging from 700m/min to 800m/min, providing stable support even during high-speed turning. Available in fixed, travelling, tandem, and end-machining configurations, the STA series offers flexible integration across a wide range of machine tools and applications.
