ER32 Collet Chuck for Proxxon PD 400

[Wongster]

After another hour plus, I'm at 50.03mm...



Should I bring it down further to, say, 45mm before flipping it over? I'll be cleaning up the should at this point.

Surface finish not that nice. Can see some little "pot holes". During cut, I heard rough sound at times and clean shearing sound at certain section. I'll put on the carbide insert tool with radius tip to clean up the surface a little before flipping over. This is just to test if I can get a better finish for later use.



Still can't do a better close up... Will bring out my new camera for a closer shot to show the pot holes.

Time to go work. These days, I dislike having to work on Sunday. Thank God it's only 4 hours this time.

Regards,
Wong
