My employer is in the process of buying a new HAAS VF4-SS, one of the major debates left was 300 PSI or 1k PSI for Through spindle coolant. We were informed today by the salesman at our HFO that as of yesterday the 1k system is no longer available. Their reasoning is the flow rate and pressure between the systems is similar enough for a drill with .090" coolant holes, there for the higher pressure system is not needed. I have seen previous posts on this forum stating that on smaller drills (<.250") 300 psi is not sufficient, there for this decision makes little sense to me. Any one else think this is an ill conceived move? Also can anyone confirm that the 1K PSI system is no longer available?
