Scope
This document presents the series of conicities and cone angles for general-purpose cones in engineering technology, with cone angles ranging from 120° to 0° (excluding), or conicities ranging from 1:0.289 to 1:500. The values presented in this document are derived through calculations.
This document is applicable to smooth cones, but not to pyramidal cones, conical threads, or spur gears, etc.
