Good stuff, John! After making a fixture I always find it a good idea to make a machining template for it. That way I can use it in a future job without a lot of faffing about.
Beautiful machining footage! I would have totally thread milled that center hole thought. I thread mill pretty much every thing larger than m5 BTW, I am so jelly of your crazy high spindle speed.
Well done John, they are powerful way of holding a part, I made my own from aluminium, a simple countersunk bolt, it wouldn't have the same mechanical advantage as the real deal, but it worked very well
I plan to try making my own at some point in the future. For these parts, I wanted something I was confident would be reliable. Especially because I'm not holding onto much material.
Hey John, Quite informative. Is this id clamp available for 5mm components? We have a rotary blade of id 5mm to sharpen edges, and we really struggles to hold the job for production.
Can't wait for the next video. Have been looking at using these for some of our jobs. Thanks for sharing.
Thanks. I have another video I'm editing about adapting one of these to work on my 4th axis.

Less faffing about > more faffing about
Thank you for the very interesting video. I never knew about internal clamps. Now I know.
Definitely very cool. And as others have pointed out, they're not that hard to make.

Yea, I need to buy some thread mills. And I'm really enjoying that 30K spindle. Plus the tool changer.
Nice one John! Can't wait till November :)
Thanks. The plan is to drop the video on November 18.
Interesting video dear man. Thanks 🙏
Glad you found it interesting.
really enjoyed that also new to me :)
Glad you enjoyed it

good video johnsl
Thank you!
Do you know how you would clamp a part with a slot?
yay

It looks like the smallest on sold by Miteebite might work: www.miteebite.com/products/id-xpansion-clamp/
@@JohnSL Dear John,
Thank you so much for the useful information and link 🙏
Stay safe and healthy, Take care.
Best regards
Nice. It's a reversed collet.
Also called an expanding arbor.
Yup.
no milky coolant, what do you use? I see its clear.
It's Blaser Synergy 735 coolant. I chose it because it's clear, which is great for video.
What would be the best material for this expanding collet ?
These are made by Mitte Bite, and their web site says they're made from 12L14 steel.
