Product Overview
This high-precision guide bushing is specifically engineered for Tsugami BO20 Swiss-type CNC lathes, ensuring superior stability and concentricity during high-speed machining. Designed for bar diameters from BC3.5 to BC20, it provides exceptional support for long, slender workpieces—significantly improving machining accuracy and surface finish.
Guide bushings play a critical role in Swiss-type lathes by supporting the workpiece close to the cutting zone, minimizing deflection and vibration during operation


The Guide Bushing for Tsugami BO20 Swiss-Type Lathe is a critical precision component engineered to meet the exacting demands of high-speed, high-precision machining on Swiss-type CNC lathes. Specifically designed for bar diameters ranging from BC3.5 to BC20, this hardened alloy guide bushing provides exceptional stability and concentricity, directly impacting machining accuracy and surface finish quality.
In Swiss-type lathes, the guide bushing plays a pivotal role by providing rigid support to the workpiece extremely close to the cutting zone. This proximity is fundamental to the Swiss machining principle, effectively minimizing deflection and vibration during high-speed operations, especially when machining long, slender, or complex bar stock. The result is significantly improved dimensional accuracy, tighter tolerances, and superior surface finishes on the finished part.
