[QUOTE="SidecarFlip, post: 635234, member: 39764"] Sounds to me like the ball screws have lost their balls......:) Interestingly, I read Gary's comments and took them with a grain of salt (to coin an old adage)..... Both my mills pee way oil all the time, actually the only machines that do that. I'm religious about stroking the oiler prior to and after using and regularly, I have to sop up extra lubricant laying in the saddle area... and I'm always watching the screws (gotta get down underneath the table and look) to make sure that they are getting oiled properly, but that is just me. I'm critical of my employees when it comes to maintenance too. Nothing focks up accuracy and/or machines faster than the 'I just work here and I didn't pay for the machinery, so what the hell, just run it attitude'...... Sounds like a combination of shot Gibs (got any adjustment left?) and dry screws that have eaten up the balls. Me, I want 'fluid' movement (fluid being the boundary lubricant between the metal and the metal. Way oil is cheap. I use a lot, on everything with slideways. Of course that means tramp oil skimmers on flood cooled machines but that is a small price to pay for way longevity. I apply the same principles to the air compressors (which are usually run hard and not maintained as a rule)..... Intake filters are cleaned every 3 months, I use K&N washable filters in the Solberg housings and lube oil is changed twice yearly and I use Mobil Rarus Synthetic in the reciprocating units and specified Mobil in the rotary screw.
