Frequently Asked Questions
Can you manufacture bushings and sleeves to my drawing?
Yes. All bushings and sleeves are made to customer drawings. Send your drawing with material, tolerances and quantity.
What is the minimum wall thickness you can achieve?
Typical minimum wall thickness is around 0.5 mm, but this is material-dependent. Softer materials like brass can achieve thinner walls.
Can you machine hardened or bearing-grade materials?
Yes. We routinely machine hardened steels including 52100 bearing steel and 17-4 PH stainless steel.
Can you achieve tight concentricity between ID and OD?
Yes. Swiss CNC turning is well-suited for concentricity-critical components. Please specify your concentricity requirement on the drawing.
