Thanks for your input.

I've been getting this boundary lines that show up when face milling between passes. Now I have decided to find the root of the issue.

I've used my TTS Touch/digital dial indicator, dropped Z...

No, it does not slide freely, a constant force on the corner of the stock will make it rotate or slide. I see about the alignment pins. The idea is to be able to mill fully around the part in one...

Thanks guys,



The chuck is 4.3" x 2.3".



That's Durometer 60A. I am using 1430K55 which is Durometer 50A, which is softer. So could it be that? My pocket is the same as yours. Are you...

Please excuse the rookie questions;

I want to mill a blind hole that is 2.9" deep (0.5 Dia). Can I just use 3/8 end mill that is extra long (4" or such) with flute LOC 2" and get it deeper to...

Thanks to all for the reply.

I wanted to decide on a method and set up a small section or a booth for that and do all in-house for the cost and time considering it maybe re-done as well.

Maybe not Tormach specific. Going to start making small parts on my new 440. All ALU.

What do you guys do with finished parts? Left mill-finish? Is it a problem if kept in mill-finish?
