I noticed you started with tiny cuts. Would it not be better to start with a fairly deep cut to get the crust off the casting? The CCMT inserts that you have seem happier with big cuts, at least on my machine.
I think I was just being cautious to be honest, only the one casting an all and the tips are 07`s , I agree sometimes its best to get under the scale as soon as.👍
You are right especially with HSS steel tools. The crust contains sand bits but it also is in contact with the sand on freeze up. This can cause a light skin of white iron to form which is hardened. The quorn castings have in the past been annealed which should solve this problem.
Hi Badger, very professional videos are getting better, thanks for your time. Regards Beagles.
