FAQ
Frequently Asked Questions
What tolerances can you achieve for motion system components?
Swiss CNC turning achieves ±0.005mm tolerances and 0.01mm concentricity for multi-diameter shafts. Specific tolerance depends on geometry and material.
Can you manufacture gears for drive systems?
Yes. We manufacture spur, helical and worm gears with module 0.5–8, using CNC gear hobbing and whirling machines.
Do you support prototype development for new robot designs?
Yes. We support prototype development (1–100 pcs) with full engineering support, then scale to production as your design matures.
