Excellent video. I was wondering about the grease fitting - knew I couldn't get a grease gun on them. My spindle heats way hot. I have attempted the fixes discussed in various forums but I can't get the flow through the spindle with the pump provided or a new pump. I have a new pump of the same type and I only get drips out of the spindle, this is after blowing lots of gunk out of it. I believe it is only a matter of time before it fails. i have a new spindle but haven't put it in - I will when the one OI have fails. Now you have me thinking about possible modifications to the cooling system.
Thanks for your video! Can you tell me what fuses you installed? I was going to do the same thing but didn’t think about adding extra fuses. Thank you!
Hello. Great idea and I am attempting to do a very similar setup. Right now I’m have major problems with leaks on the outlet side of the pump. What fitting did you use off the pump to the CNC tubing?
Thanks so much for the rundown on your cooling system. I had the impression that antifreeze wasn't a good idea for water cooled spindles (or maybe that was bleach in a water system). How long have you been using antifreeze in your system? Have you ever changed it out? I like the radiator idea. I was going to comment on the amount of dust in your control box but then remembered that our makerspace cnc's controllers plus the computer are sitting in the open on a shelf under the cnc and are usually covered with a layer of sawdust. ;-p
Richard Farwell I been running the antifreeze since I put the new pump on, that was when I also put in the hour meter and today it has about 295 hours.
I have been a maintenance engineer for 40+ years. Excellent preventive maintenance sir!!
