mcmaster conversion notes
TODO
DONE
Verified I can unscrew the posts from the base
When I showed sales rep pictures, was told I was recommended the following parts:
1P5AC-1000: Vacuum chuck body and tube - to convert PP5D to PP5GT
1P5AC-0600: Drive/conditioning ring assembly for PP5 Polishing Jig - grooved
1P5AC-1200: Vacuum chuckface for PP5GT - annular grooves for 83mm diameter substrate
1GAG-055: Bluetooth gauge with support clamp (jig serial number required)
Follow up:
1P5AC-1000: doesn't my unit already have this? What is the difference between this one and mine?
1P5AC-0600: my driving/conditioning ring face is smooth, the recommend one is grooved. Does this provide a process improvement?
1P5AC-1200: Will this mount to my existing chuck face body?
The post screws do in fact come out. I think they are just standard M6 optical posts (TODO: confirm). I don't need vacuum capabilities, where I think a lot of the complexity comes from.
Options:
Buy all parts and get running. This is a significant sum, with the lowest cost part about what I paid for both jigs combined
Jury rig something (ie an SBT chuckface) onto the assembly. Replace with shorter posts
Design parts and get machine shop quotes. Most parts would probably be pretty simple to make since I'd be okay with wax mounting
