    Haas Super Mini Mill - Controlling the Coolant Blast

    My Haas Super Mini Mill has the Programmable Coolant option. The problem is that in many cases the coolant ricochets of the part and carries chips up into the umbrella tool changer. Some of these chips stick to the tapers of the toolholders and prevent a proper fit into the spindle. I end up with erratic cut depths and tools that don't run on center. I end up having to constantly stop the machine to clean the toolholders and the spindle - what a waste of time! Has anyone else had this problem? Is there a way to decrease the coolant pressure?

    We have a main valve on ours, just cut it back a bit. We also installed valves on each nozzle to adjust flow. You could also install a bypass valve to shunt some of the coolant back to the tank.

    Re: Haas Super Mini Mill - Controlling the Coolant Blast

    We were having issues on our Super Mini mill, and once we installed new springs on all of the sliding covers on the umbrella tool changer it really helped with the issue of the chips getting onto the tapers.

    What was happening was the sliding covers were not closing up completely when the tool pocket was empty and that was allowing the chips into that area of the tool changer.

    When we removed the tool holder from the machine we changed all of the springs even if they were still someone working ( they are not very expensive, so I figured since I had the tool changer removed it made sense to change them all )

    Haas has a good video on how to change them out.

    It really wasn't to hard of a job, but make sure you have someone to hold the bottom of the tool platter when you loosen the bolts so it doesn't fall down into the machine

    It sounds like you don't have the programable P-Cool he is talking about, but he could install a valve on his main supply line to the P-Cool unit and control the flow with that valve

    That is correct, no P-Cool on our machine.
