Re: [CAD_CAM_EDM_DRO] Coolant Question (was Re: Swarf Removal)

Hi,
On my Fu Wrong Mill/drill, I drilled a horizontal hole in the End of the
table and then a vertical in the bottom of the well to match up with the
horizontal hole. The horizontal hole was tapped for a 3/8" pipe thread so I
could attach a PVC tube to it and drain into my bucket (er....sump:-})

Obviously, I am using a flood coolant (water soluble oil at this point). I
made a shield that sits on the table, but most of the time, I just adjust
flow by use of a 1/4" ball valve in the supply line. I find that by
careful in the amount of coolant splashed on the work, there is little
splash on the floor.
