Milling Crash Course

[jimustanguitar]

I've been googling videos on milling to gain a baseline understanding of the terminology, tools, holders, processes, etc. Glacern tooling has a 9 part milling crash course playlist that seems like it covers the fundamentals nicely. 












And since I'll be using ER20 collets for starters, this video from Haas (which I posted in another thread, too) is a nice way to understand those.

And here's a nice video about milling vises, variations, and quality.

This guy lost a bit of credibility on this video with his fans. It has a lot of info in the video and worth watching for sure, but It's pretty obvious that he is biased to the expensive USA one that was given to him to do the video, and the caparison is really apples to oranges. The China vise isn't in the same league, obviously the USA one will be a better vise, It's not a fair comparison. His fans ripped him up pretty good in the comments (if he hasn't deleted all of them). He also made a jab at AvE, which a lot of people didn't like. AvE buys his own things he takes apart and doesn't allow companies to "give" him tools for a "good Review". Not sure if it was done in good humor or sarcasm, others may have taken it the wrong way.

I have to agree with a lot of the machinist out there in other videos, it all comes down to tolerance and what you can afford. Do you need it to be 0.01, 0.001, or 0.0001. For a hobbyist, the China vise is most likely sufficient. Of course when we get moved and get some grants, we will be buying the best vise we can afford for the best mill we can afford. Even after using the "decent" china vise on our china Mill, you will instantly recognize the value in a good precision vise.

He did a follow up to that video. I haven't finished either yet, so I guess I saved the fun part for later

Yeah... That first video is great for education, but it's no shootout. He's comparing a base model generic to a hot rodded premium. There are interesting bits about both, but they're in different playing fields and price ranges - not a comparison.

Still interesting information about how they're made, what makes them accurate, how they flex differently when used, etc.
