Is someone able to tell me his/her opinion about oil-base coolant Blassomil22?
I got that stuff and only aluminum goes ok, steel 12L14 looks like s... (I mean surface finish). Turning 4340 with 55degKennametal KC5010 kills insert very quick (100-150 parts). Previously I was able to make 500-1000. Salesman told me I should be able to machine 12L14 but it seems like only Aluminum 2011. Feed and RPM used during turning - recommended by Kennametal minus 30%.
Any opinions about that coolant?? thank you.
I am surprised that you are having that much change in tool life by using that oil. Be ure that you do not have another issue, alignment, etc. before changing your coolant. We use all Blaso products here, mainly the Blaso Mill Uni 20 or Uni 10. i prefer the Uni 20 because we use 2000 PSI high pressure pumps and this works well with this pressure. But also when running standard pressure I have no issues in most mterials we cut.
The only thing I have changed was the oil, before Hangsteffer 5228(or something like that) Hard Cut, now Blassomil22. They recommend that oil for swiss, and for light machining. I understand 4340 at depth .125" is not the light machining but I'm surprised 12L14 gives me so much problems. I should have use Vascomill according to maker's website, but I wanted to know what the others thing about that oil. Thank You for an answer Tcooper571.
