Hello,no sense if you realize centering before turning on the top and arrive over it in header.This generate a tracing drool so you need to restore at the end.
You not use it so the things not needed it's only lost time do that.I suppose you do that for replace a misalignment of the outside tools....
Another observation:you use shorter clamps and a smallest diameter than total lenght of the parts.When I look on that have idea you
turn outside diameter too but was not.In this way you can use longer clamps and over outside diameter.
You will have safety job and can push more and more over cutting parameters with more precision too.

Put the tailstock on and you can run so much faster. I always use it

@@dennisdanielsen1953 I didn't feel the need to do this since it was a short piece.

Looks a bit slow on the DOC and feeds. Watch your machine's power monitor to see if you can improve the roughing operation. I run parts like this at 2,5 - 4 mm DOC and around 0.5 mm/ rev using a W insert with 0.8 or 1.2 mm nose radius. Especially increasing the feed rate is always a good idea - it improves chip breaking practically always.

@@bigbattenberg Thank you for your interest and suggestions. I generally lathe with Q 4mm chip, 400 rpm, 0.25 feed. But I will try what you said as soon as possible.

@@MasterTornaci We run a small and a large Okuma lathe and with the small one I aim to be at about 90% spindle load which means about 2.5 mm Ap and 0.5 mm/ rev. (typically in 42CrMo4). Using those settings on the much more powerful big lathe gives only about 30% spindle load so I can take much heavier cuts, right up to the maximum indicated by the carbide insert manufacturers. It really pays to optimize because most of the time is spent roughing. Also of course it is interesting to watch you insert wear.
One last thing to mention is directed coolant flow, just last week I read some information from Ceratizit claiming that tool holders with nozzles directed to the cutting edge especially from the bottom can massively increase performance and insert life. I have to dive further into this. Of course you have to first determine if you machine has adequate coolant flow and pressure to use this technology.

Why you dont use a tailstock? Then you can easily increase cutting parameter 😊

[@MasterTornaci]

@@burghardtzerspanung I use the tailstock for longer pieces.
