    Overcome the Noisy Haas Coolant Pump?

    Hey All, We have a 6 month old Haas VF-2SS. It's the first Haas I've worked on and I like most things about it. But MAN is the flood coolant pump loud. I've seen others complain about the same thing on the new machines around the internet so I'm wondering if anyone knows of a good way to quiet...

    Fadal VMC40 Y-Axis Ball Nut Installation

    Hey All, I did something foolish, which was to remove the Y-axis ball screw from the ball nut on my '92 VMC40. Now I've removed the ball nut, collected all the balls, and am trying to reassemble it. Inside the nut, there seem to be a couple ball catcher things that allow the balls to feed in and...

    Fadal VMC40 Y-Axis Screw Coupling Question

    Hey All, I've been having some trouble with the Y-Axis on my 1992 VMC40. When rapids are set to 100%, it makes this strange shuddering noise when moving on Y. I'm also getting terrible position repeatability. When moving the table by hand, I noticed a "thunk" whenever I changed direction. I...

    Fadal VMC40 hi/low Speed Change "squeak"

    Hey All, Just had a new VFD installed in my 1992 Fadal VMC40. While running through tests, the mechanic and I noticed that when the spindle is running at, say, 500 RPM and then is changed to 3000 RPM, the air system engages the high range belt before the spindle has fully stopped and the belts...

    Rookie Tool Length Offset Question

    Hey all, After years of manual machining, I'm finally finding my way into the world of CNC. I have a 1992 Fadal VMC40 with the 88 controller. I have realized that I know absolutely nothing about TLO, even after reading loads of articles. Here's how I do it now: - Place 1" gage block on part -...

    Rolling Thin Wall Brass Tube

    Hey All, I'm not sure this thread belongs on this site, since it's not about machining, but I'll give it a shot: I'm rolling some 2" O.D. x 0.050" wall brass tubing for a bar footrail and I'm having lots of trouble. It's kinking, obviously. I'm using a JD Squared Model 32 tube and pipe bender...

    Mitsubishi Inverter Troubles

    Hey all, I posted recently about the Mitsubishi Freqrol Z300 Model FR-Z320-7.5K-UL inverter in my 1992 Fadal VMC 40. It seems the brake resistor has been getting wayyyy too much current, enough to melt its aluminum housing (see pic 1) and create a fair amount of smoke. After testing, all of...

    Dangers of Working with Inverters?

    Hey All, I have a 1992 Fadal VMC40 with the mitsubishi Freqrol Z300 Model Z320-7.5k-UL. I often get a spindle fault upon starting the machine, but when I let it warm up and sit for half an hour or so it works no problem. I figured it was the inverted because I was getting an alarm on it and...

    Hey All, I'm not sure if this has been covered somewhere else but: I'm having trouble naming my programs. I've had this 1992 Fadal VMC40, my first CNC, for a few months now and have been just keeping track of what program number corresponds to what, but I'd like to have comments in the title...

    Good Circuit Board Cleaner?

    Hey All, My 1992 Fadal VMC40 arrived with a bunch of gunk, crud, goo, junk, dust, etc. on a lot of the circuit boards. I'd like to clean them up a bit. Any good recommendations for a spray, non-conductive, affordable circuit board cleaner? I was given some recently that was insulated to 60,000...

    Hey All, This may seem ridiculous to some of you, but I'm looking for better looking, more "stylish" safety glasses for myself and my team. As a high-end art and architectural metalworking shop, we are trusted to make important aesthetic decisions and execute them exceptionally well. Our...

    Fadal VMC40 Spindle driver fault - servo amplifier fault

    Hey all, Came in this afternoon, turned on my Fadal, went to warm up the spindle and got a "SPINDLE DRIVER FAULT" with "SERVO AMPLIFIER FAULT" on the next line. All axes jog and move fine. Now, spindle most of the time doesn't start at all and the message "SPINDLE CONTROLLER OR DRIVER FAULT"...

    Start - Stop Push Button Wiring

    Hey all, long time reader, first time poster. I'm having a difficult time figuring out how to wire an old GE start - stop push button switch to a 3-phase motor. This is for a friend of mine who has a wood jointer across the street. I usually don't touch jointers, as they are how I became...
