Swiss Lathe Guide Bushing

Swiss Lathe Guide Bushing is a core accessory for Swiss-type automatic lathes. It holds the bar stock during machining and provides stable support and guidance. This reduces bending and vibration during cutting. The accuracy of a product directly affects the roundness, straightness, and surface quality of machined parts. We provide product parts for major brands including Star, Citizen, Tsugami, and Tornos. We use precision CNC lathes for inner and outer diameter finishing. This ensures accurate fit between the guide bushing, machine spindle, and bar stock. We specialize in high-difficulty custom parts with micron-level precision.

Swiss Lathe Guide Bushing parts require extremely tight tolerances. Any deviation affects part quality. Our capabilities include inner diameter accuracy of ±0.005 mm for bar stock clearance. Outer diameter accuracy is ±0.005 mm for machine spindle fit. Roundness is ≤0.003 mm for high-speed rotation stability. Cylindricity is ≤0.005 mm for consistent guidance along the length. Surface roughness is Ra 0.2–0.4 μm for smooth bar feed. The inner hole of a product requires precision grinding, not just turning. We combine CNC lathes with surface grinders. We machine inner and outer diameters in one setup to ensure concentricity. Common materials include powder metallurgy steel, tungsten carbide, and bearing steel.

The service life of a Swiss Lathe Guide Bushing depends on material hardness, work material, rotation speed, and lubrication. We use powder metallurgy steel with good wear resistance and self-lubricating properties for high-speed applications. We use tungsten carbide with high hardness and wear resistance for stainless steel and titanium. These materials extend the life of your product parts for high-volume production. We are ISO9001:2015 certified. We recommend keeping spare product parts in stock. This prevents production downtime when bushings wear out. We support non-standard customization.
