Milling and casting polymer ...

[Mohammad Khair]

all vertical mills have a relatively high tolerance specially those light weight ones.
only lathes have the minimum tolerance, some of them less than 3 micron they said.
but all those numbers are pure theoretical.
no wander if a light vertical mill has a tolerance of more than 30 micron.
to get low tolerance you must mill softer materials.

do you think it would work to mill a full puck in wax, then cast the puck, then put the puck back on the machine and mill the screw channels and implant interfaces ?

 

[CoolHandLuke]

i don't think so. that cast would have to be 1um over 98mm tolerance accuracy. ridiculous.

no need for that.

then getting it back in the machine in precisely the same spot... no angular or lateral movement.

You must use a high-quality wax, high density and without bubble, I saw discs with micro bubbles, pas bon !
I found this wax in Brazil, I like it like the samba !
