Case Study:
MIRROR MOUNT FOR DEFENSE TARGETING SYSTEMS
Challenges
Mirror Mount For Defense Targeting System:
- Very tight tolerances
- Flatness and bearing journal alignment
- A lot of material removal
- Nonsymmetrical part
- Prior efforts resulting in stress relieving and part deformation
Project Summary
Mirror Mount For Defense Targeting System:
This part had multiple challenges for the following reasons.
Overall length 16’’ x 5.00 Diameter
The part was designed to be cast aluminum with only the critical features left for machining, however due to the qty ordered (400 pcs) the customer agreed to solid billet which introduced other challenges.
There was a fair bit of stress relieving from removing large amounts of material and the part being non-symmetrical in shape.
Rough machining was required along with stress relieving heat treat before final machining. The bearing journals required very tight concentricity of .0005 as well as .0002 OD tolerance and the large flat mounting surface required a flatness within 0.001” across the part.
We intended to turn the journals between centers however the tail stock pressure was too great and pre-constrained the part causing deformation once released in the free state. The final solution was to fixture the part onto a rotary table without pre-constraining the part, this allowed us to OD machine the bearing journals with precision boring heads and maintain the concentricity requirement.
There was a total of 10 machining operations to complete the process.
