Femoral head
Since cobalt chrome is an abrasive material, the challenges when machining the external sphere include getting a high surface finish, reducing vibration using longer tools and getting inserts to run a full batch.
Benefits:
- High quality surfaces with positive round inserts
- Increased tool life
- Secure process
Machining solution
- Rough turning: Use T-Max P. Use HP for chip control and process security.
- Semi Finish/Finish turning: Use positive round insert. (for more information, see below)
- Parting off
Machining solution – semi finish
Machining solution – finish turning
Selected component features
- External sphere
- Taper hole
The challenges when machining the taper hole include getting a high surface finish, reducing vibration using longer tools and getting inserts to run a full batch.
Other challenges when machining the taper hole is the use of small tools and to handle vibrations, but also to get a flat bottom hole- for Laser etch ID.
- Flat bottom hole, for Laser etch ID
- Small tools
- Vibrations
Benefit:
- Effective process for flat bottom
Machining solution
- Drilling with CoroDrill® 846
- Rough turn taper bore and finish flat bottom(for more information, see below)
- Finish turn taper bore
Machining solution - rough turn taper and finish flat bottom
