machining ballscrews

[T0rnado69]

I've machined them before with indexed tip for hardened material without any trouble.!!
Send Chai an email along with drawings asking him for quote.
Lee Chai doesn't Mind is email being given out he gives it out him self on Ebay.!!

hi dean, i currently use brazed TCT tools i got from machinemart.
6 Point metal turning set and 38pce Carbide Tipped Lathe Tool Set

but have been planning on getting an indexed tool for a while, as they look much better and you just change the cutting tip.
as with the brazed TCT ones i have, you have to take them out and get them sharpened.

where can i find chai contact email..
cheers.

This is the machining diagram used.

thanks for the diagram eddycurrent.

You can do it with hardend tips if your lathe is beefy enough.
Its also handy if you have a collet chuck to hold the screw in the lathe.

the lathe is the clarke cl430
it doesnt have a collect chuck, just a 3 jaw and 4 jaw chuck.


thanks for the info corkcnc.

That's a good point, I used a lathe to straighten some ball screws and a standard chuck does not grip it well.
