Thread: Turning Silver Steel

Cheers gents

You've all helped a great deal, and taught a novice a lot. The centre was very close to the tool, but just about cleared. Russell your suggested speed rate really helped. Shall polish them later on.

Thanks again

Cheers gents.

im using carbide tips (for stainless material) I hadn't used a centre to support it as I didn't want to centre drill the end of the material, purely for cosmetic reasons. I'm running the machine at about 800rpm, is this too slow? I have plenty of material so will try machining with a centre support first.

really appreciate the help

Hello.

I was wondering if anyone could help, I am trying to turn 8mm dia silversteel down to 5mm. (first time i've used it)

The problem I have is that the finish and accuracy is awful, although the closer to the chuck the more accurate the finish, its 0.4mm out the furthest point away from the chuck. (50mm hanging out of chuck)

I'm using plenty of coolant, applying a nice steady feed rate and using a sharp facing off tool.

Any suggestions would be hugely appreciated.
