For Sale (Used)
Converted X2 mini mill from LMS that was put together by me, and had made all the parts that fit the machine. Ballscrews were done in my house, are from Roton, and replaced the origional ball's with oversize, to get a fair amount of backlash removed.Thinking back at the origional ball nuts was around + - 0.0017 to + - 0.0036 to + - 0.0018 To this day it will hold + - in X and Y to 0.001 and Z - 0.0005 that is at around 70 to 88 degrees F. here in Florida, garage kept indoors.
The belt drive is of my own design, which looks like so many familure designs, but a little here, and little there, and uses an vacume cleaner V belt, that is readily available at any store around here. Made the ball nut mounts, before there was any available online, and a few other changes to the gibs and the cast rubbing plates for the gibs. Most screws got change to imperial on most of the machine and castings were cleaned and milled accordingly. The motors are 521oz 34 nema OLD round type, as all I could get at that time, was a fair deal from Camtronics, which I also bought there controller box also, with Gecko 201's inside, and wired for the motors at peak preformance from Dan. Rapids can get to 140 ipm, but 90-95 ipm is just fine.The Controller Box ( Is Not For Sale. Also, the stepper Motors Only and handwheels I would like to KEEP ,as they are for another build, and Not included in the deal) , the couplings, stay with the machine. You would need to get a controller anyway and rewire your new motors to suit. It comes with the original spindle motor, extra brushes, and origional controller from LMS and works fine, but could use more torque as many have changed this to a surplus center KB unit or other. Never had an issue with anything except operator error, It happens to the best of us. Many spare parts are included with the mill, if you want, as I have no use for, or if you would like to go back to maunal operation, Note: some parts are broken and or bent from the cnc conversion. It is a fine mill, no trailer queen, and has made many many parts, and replacement parts, for the home, and community around here, every body always wants something to be fixed because they don't make it anymore, or its too expensive, and the favorite is, its got to be HD, Tim Allen aka. Tool Man Stuff. On one note someone asked about the ballscrew in the back being mounted for the head, and said it would stick or something to that effect, and my reply is, it goes up straight, and comes down straight, been trammed once, and has remained that way for years and counting, even made all the parts for my new mill on it, and client parts also, had no worries, or doubts about it, for what it could, or could'nt do, besides being TOO small for my needs now. I'm happy with the results. Now the LOWDOWN is, Local Pickup Only !!!!!!!, OR... USA ONLY.. If you have Any Questions, I'll be glad to answer, for I am busy making parts for clients, and other parts building, and a life. Please Be Patient ! I'm not going anywhere, Just Busy. Asking Price is $800.00 ?? AS IS........
