Ugh; seems my good luck has run out. Right when I get an order for 50 sets of parts my machine starts giving me fits.
This last weekend I used to machine to make some parts - all went great. I used my flood coolant like always and by the time I was done my coolant was looking murky so I decided to change it with my next run.
Today I go out to the machine and home it. The y-axis makes a metal-on-metal squealing noise a bit but homes OK. I'm good about giving it a few squirts of oil with the oiler before milling anything every time. So I figure it might need more oil so I give it a good number of squirts (6 or 7) and start running the axis back and forth to spread the oil around. It keeps making the squeal but the noise is quieter except every couple of times in several different spots it jams and I lose steps. I go back and try and oil those spots specifically by squirting on them and traveling back and forth other them and it seems to get better, almost totally eliminating the sound and no more jams. I go over the whole travel giving it a squirt every inch or so (going though all the oil in the oiler and then some in the process) and then do a few more full travels. Either no sound or minimal sound and no jams consistently.
I go eat lunch and come back in 30 minutes. It's back to jaming again worse than before. Now I'm really nervous something bad is wrong and honestly, I don't even know where to begin. We've had several days of cold and hot alternating weather and I'm worried my bad coolant somehow got into the ways and rusted something but I've looked under the covers and everything looks ok (and is totally swimming in oil). I'm going to get a small screw driver so I can actually remove the way cover in the front (without removing the enclosure) to really see but from everything I've seen, it looks good.
This is a new problem for me, any suggestions on where to start looking? When it jams, a little bit of hand pressure and it un-jams, so that's odd too. Thanks in advance for the help!
