Machining Large Billet Molds on a Haas VR-9 5-Axis at Mallory Pattern Works

nice looking shop

our company just bought a vr9, so far very disappointed. Trying to tap a plate with 481 holes, keeps going into z axis encoder fault. Been 8 days no word from Hass tech service yet. Also the coolant flow is terrible. Says the high speed pump should flow at 12 gallons a minute, ours is pumping about 10 gallons in 5 minutes, don't see how we're suppose to use it on a mold when some cavity's we cut out 6 to 8 inches deep. The haas tech is trying to tell us that's how the pressure is on a vr9 5 axis. I noticed when haas shows you how the high pressure coolant pump works they are not using the vr9 in the video.

Sorry to hear that, what city and state are you located in?

@@hfotridentmachinegroup we're in Fountain , Colorado.....haas just told us today the machine is designed for 2 gallons per minute coolant flow which is terrible, not sure how we're gonna make this work. We wanted to see one before we bought this but they said none available in our state. There is 2 of them but you needed security clearance. How do you flush the chips out efficiently?

@@mounta59378 we are the HFO in 14 states, mostly in the Midwest and Northeast, which is why I ask. Have you considered a high-pressure coolant system, like MP Systems? I'm not a service tech, so forgive me if that's not something that would solve the issue, just a thought.

@@hfotridentmachinegroup Haas does sell a higher pressure pump but we were told would be a waste of money because the line coming thru the 5 axis head is only a quarter inch diameter
