Frequently Asked Questions
Do you support humanoid robot development programs?
Yes, we are a head-tier supplier of humanoid and collaborative robot core parts for one of the world's largest collaborative robot manufacturers, with expedited sampling and 7-day batch delivery on repeat parts.
What tolerance matters most on robot joints?
Feature-to-feature accuracy between bearing bores; that is why joint housings run on five-axis or turn-mill in one setup rather than across two.
