Hello to all:

I am getting ready to mount a Huanyang 2.2 kW water-cooled spindle on my Kuka robot arm. I plan on using orange auto-coolant (to avoid stuff "growing" inside my system) and a heat-exchanger (http://ugracnc.com/CNC-SPINDLES/Heat...System-2X.html)

One thing I'm not sure about: how long should I make the hose runs? My Kuka has a spot on top of the arm to mount external equipment (welding power-boxes, etc)....but I don't know if my hose runs will be long enough/have enough coolant in them with this plan.

Thanks for any advice!
