Threading with a Geometric Die Head
Вставка

- I thought today was as good of a day as any to make a geometric die head video, I bought this when I restored the turret late and have been using it regularly ever since.

Thank you for sharing, I recently started using die heads as well. I also found very little information about their use online. I have found that I have the best results when I allow the turret to feed at the pitch of the chasers, It’s nerve racking, but it just works. Also, I use flooding oil, they need tons of oil to work best, it’s also very good for your machine. There are remastered company videos from Geometric that have a wealth of information on here.
That attachment is so cool. Glad you get your hands on one. I’ll check out more videos.❤
Very cool machine
that is cool.
Just purchased a Jones & Lamson 16S threading die head on Ebay,
Very cool, thanks!
im a threading specialist from detroit and i recommend that you increase your feeds and speeds to not have the tooling engaged for so long heat is not good for the chasers shoot and scoot.
There is no feed to adjust, the chasers screw them selves onto the bar and pull the turret / geometric along with them however perhaps a higher rpm wouldn’t hurt I just simply do not know what the right rpm should be and at $100 per chaser I don’t like to experiment
love the machine @@westislespecialprojects
Hi there, nice video, I'm in the Uk, and I use something similar but smaller than you have, but it does look like your's is a Coventry Die Head, or Alfred Herbert Die Head.(like mine) On mine there are two settings, for a rough cut and a finishing cut, so you might look and see if yours has the same facility. When first engaging with the bar stock, make sure you compress the spings in the head to ensure a good start for your thread, hope you don't mind my imput, I've been using these things for years, take care, Dave
Thanks, it’s a geometric brand as far as I know. Did you watch the whole video? particularly the part about the roughing and finishing lever? Your comment suggest you didn’t make it all the way through
Yes, I did watch all the way through, sorry I missed that bit! That's great then, gives a better finish. sounds like my die box then.👍
That is a Geometric Die Head, it looks like a DDSA type, and about 1-1/2” size. Thats a nice heavy duty die head with all the features one could have.
I know them as Herbert die heads but that was probably because that's what the company had in stock. We had ones suitable for 2BA up to 2-3" BSP, maybe bigger it is getting a bit fuzzy after 30+ years. Most of the stuff was small so the Ward 7 was far to big.
You lathe Must have enought torque in order to keep that much of power.
Thank u for the information i have a turret lathe with 2 geo heads
테롓(헤드)선반 ? 구입가 얼마입니까 ~!??
Great explanation! I understand that the geometric die is easier and faster, but can you also single point thread on this machine, like you would on a regular manual lathe?
No it can’t, it has a variety of feed rates but none that will match the pitch of a thread.
@@westislespecialprojects thanks for the explanation!
Is there a way to install a compound rest on a heavy turret lathe like this?
Not on mine
Sir I want to training with u
