ID boring and threading with the Tormach 8L lathe! This project helped me brush up on boring and threading skills and is a great example of how to approach machining any part from scratch. We’ll discuss material, tooling, speeds, feeds, and Fusion 360 CAM.

Vince, where is the Fusion file for this? The link is broken. THanks
Awesome ??? sir
I noticed your pitch didn't match the actual thread it was for a 12 TPI. Are you just using generic images just for example?
Vince, if you have an HSM Advisor License I created a High-speed and Low-Speed profile for an 8L from data supplied from Tormach. I have not tested these as I don't have an 8L but I have been checking out the 8L as it looks like it would be quite good for the type of low volume/prototype parts I would make on them. What is the width of the bed (distance between the V's on the bed)? What do you think about replacing the 0XA tool post with an AXA size – assuming it would fit? The 0XA is what the Tormach Rapid Turn used.
ever heard of G CODE? HOW ABOUT A CHAMFER ON THREADS. inspector would say…."no bueno"
Can you please do a video on setting up lathe tooling in Fusion? The milling side is so much more intuitive.
Drilling and reaming is not the same as drilling and boring. Boring yields better concentricity and a rounder hole, if everything is done properly. Under 1/2” dia holes there’s plenty of solid carbide tooling, Swiss stuff etc.
obviously on a threaded / tapped hole the difference between reaming and boring wouldn’t matter since that ID isn’t doing much on a threaded feature 🙂
1 1/4-7 is ANSI standard coarse thread pitch. Usually designated as 1 1/4-7 UNC.
Just a clarification. Nice video.
Thanks,
John
been waiting for more 8L content! thanks for sharing.
"Lathing"
Does it have to power to cut 4.250 O.D aluminum. Great video.
Good grief, why not just machine this manually rather than messing around with Fusion? Easier, faster, surface finish just as good, and just as dimensionally accurate. As a bonus, it keeps up your manual matching skills.
Thank you for the 8L content
Excellent video! Thank you! 🙂
2:08 ouch that's a lot of tool deflection
why does your thumb look like onigiri
