Controlling deformation in thin-wall robot motor housings

A buyer-focused note on thin-wall motor housings, 5-axis machining, stress release and fixture planning for robot parts.

Controlling deformation in thin-wall robot motor housings

Thin-wall motor housings need a balance of weight reduction, heat dissipation and assembly stability. The original domestic article focused on how deformation appears during roughing, finishing and stress release.

For an overseas RFQ page, the useful takeaway is simple: buyers should share wall thickness, datum strategy, material grade and critical coaxiality requirements before machining starts.

Engineering review should look at fixture pressure, staged material removal, thermal behavior and whether the part needs intermediate stress relief before final finishing.
