Spherical Ball Seat
A contract manufacturer of both commercial and military aerospace components is required to machine a family of parts from 4340 material at 33Rc hardness.
- The form required is a spherical ball seat comprised of:
- a .750 convex radius
- Blended to a 15° taper
- Then blended to a concave radius generally between .190 and .250
- And finally facing at 90° to the component I.D.>
- The parts have in common the .750 concave radius but vary in the length of the 15° chamfer, the size of the concave radius and the amount of the 90° facing required.
Genesee designed special hollow mills using four precision ground and matched premium T-15 HSS blades, set to cut to centerline to produce the entire ball seat complete in one pass.
- This Genesee hollow mill solution has been in use for decades.
- The technology has remained constant due to the productivity supplied, even during plant and location changes
