We Have 6 Makino VMC's and are using Blaser's Blasocut 4000 Strong soluble cutting oil with DM water on all of them. We machine mostly Al6061/7075. There are few parts with Titanium and more recently SS303 and SS316. Till date we are happy with the coolants performance. It gives excellent tool life and Surface finish. Life of coolant is also good as all our machines use Grease for lubrication and there is no mix up of oil in to the coolant. Only problem we have is of foaming which is easily controlled.
Now we are machining few SS303 components having small holes (0.5mm to0.8 mm, 12mm deep). One problem we are facing is of tool life. It is inconsistant. Some drills gives 20 to 25 mins of cutting time and some drills break with in 10 mins of cutting. All drills are custom made from Guhring. Our customer is also doing these components on Makinos with same tools but with better results. Only difference is they are using stratght cutting oil.
So my question has any one used both?. Will it make any difference on tool life specifically on small tools?. Is it easy to handle. Can it work with Aluminium
Machine specs are BT40, 12000RPM, No thru spindle coolant.
