VF1 tool changer clean up & oil lube issue found!

[@gorak9000]

To get rid of that green stuff, I'd spray it with some kind of degreaser, let it sit, and then pressure wash it. A cnc lathe I got recently I used the oven cleaner trick (just spray everything down with oven cleaner, let it sit 10 minutes, and pressure wash) and it cleaned up everything beautifully! I just got the spindle drive working on that machine today! Pretty happy right now. The first time I've seen the axes and spindle move on that machine since I got it exactly 6 weeks ago

I'm guessing your x phasing error is some capacitors in the x axis drive are getting tired. When you power it up, the timing is slightly off because of the slightly failing caps, but if you power it up with e-stop in, the control side of the drive is powered up before the AC side is, and then the phase detection works properly. In these 90's vintage machines, if you want them to be rock solid, you pretty much should just shotgun replace ALL of the electrolytic caps in all of the electronics with new ones. Then the machine will be solid for another 30 or 40 years!

I have been using a heavy duty grime remover i got from Screwfix same sort of thing, i cant use a jet wash on it as the machine is indoors in the workshop so i just end up using tons of rags to do the job

I hear what your saying and i've heard lots about bad caps in electronics as you mention, i did try another servo amp drive though and another pcb but still the same issue, unless i was unlucky and they all have the same problem which would be just my luck lol

The green is 100% brass or aly bronze chips+coolant. Absolute nightmate to get rid of, it turns sticky/

[@kinzy_fabrications]

Yeah I’ve only ever seen the green reaction with brass or bronze but there no brass or bronze swarf anywhere Either way it’s a horrible mess to clean off lol

i was told to not use Vactra oil on the linear bearings .... told to use a 5 - 20 Weight synthetic instead.... that Info came from HAAS and also remove the Sintered Filter

[@kinzy_fabrications]

Yeah I used Mobil 1 in my mills for about 2 years now and have the filters removed

Hi. A question, maybe some info or even an incorrect procedure on my part. With my VF2 the spindle fan runs on for several minutes after milling has finished. This helps cool down the spindle motor & its associated electronics i.e. IMO a good idea. However, your fan is really quiet (difficult to believe - i've changed mine unecessarily), you've switched it off for video purposes or you don't find it necessary to keep it running on a bit. Any ideas ?

[@kinzy_fabrications]

Hi The noise is really dependent on the type of fan on the machine, on this vf1 and on my vfoe the fan is almost silent but on my vf3 it has a bigger different style fan and it is very noisy, I have the fan timer set to run on for 6 minutes on my vf3

[@user-iw5gb2lj9p]

@@kinzy_fabrications many thanks for the valuable info. I've got the noisy variant. Have you access to the type no. it's VERY loud.

[@kinzy_fabrications]

@user-iw5gb2lj9p the 2 types are not interchangeable due to how they mount on the machine The smaller machines vf0/1/2 with the quieter fan mount on top of the head and the gearbox machines has a noisy fan mounted in a bracket that went around the motor
