Lathe charging.

Did you try running faster? If your current tool is cutting ok, looks like it is, theres no advantage of cbn inserts.
I cant say about other styles of inserts, theres a big trade off between sharpness and durability.
The finish your getting tells me that look like the blunter sort. A light rub on diamond wheel may improve the cut, speed you can push it and finish.

Ok no not yet. Sadly I was busy but I was hoping to get something ordered for Monday.
That never materialised either.
The guy local to me has no R8 facemills but has some 17mm stub ones listed.
I was hoping for speed a trip to him for a cheap head ( he usually sells quality old stuff at well below Chinese prices but I can get it quickly.
Problem I have is he does not have, deal in , or know about tips and geometry.

I was then hoping for a trip to gloster tooling for an R8 arbour and/or face mill early monday BUT they appear to only list TPKN so....I am inclined to still go but to get some tips to see if they are better than the ones I am using. As they are unknown quality and type. Although knowing @Matt-H they won't be crap.

So yes on Sunday I will try faster speeds. I am sure life would be much easier 8f I has white water working.

I've got a spare endmill here I could send you. I know it's not a facemill but it's 16mm dimeter with three APMT style inserts. You'd need either a sidelock holder or an Er collet to hold it.

I haven't got any inserts but they won't be dear, you can buy individual ones from Cutwel.

Will be something decent, although it's got w turned down shank

Just cover the post mate. I've got a walter one exactly the same size and I don't need two. Just gotta sort yourself some tips out.

PM me your address

If you wanted a bigger one for sunday theres a small one on amazon, 20mm shank
www.amazon.co.uk/dp/B088WVV4M4/

Can send you some sharpened inserts for that, should lower the cutting force. I had good results but Id be interested to see them on a proper mill.

What mill do you have then?

 

[Kram]

The lathe. Dont expect the inserts to cut great out of the box but a light rub on diamond they cut like in the video.

What's an HO1

 

[Kram]

H01 is the chinese insert grade for non ferrous/aluminium. High top rake, uncoated and very sharp polished. Not for hard steels.

Shame I needed a 60mm facemill but the one I got did the job.
Well half of it I have another one to go.
