Guide Bushings
iSwiss Guide Bushings are precision-engineered to deliver the stability, accuracy, and performance demanded in high-precision manufacturing.
Designed for Swiss-type CNC lathes, these bushings provide rigid support for bar stock, ensuring consistent concentricity and minimizing vibration at the point of cut.
By maintaining tight tolerances and reducing deflection, they allow manufacturers to achieve superior surface finishes and dimensional accuracy, even on slender and complex components.
