    Re: Reballing linear blocks / wagons / carts

    I have done this with some knock-off Hiwin rails. Usually, the bearings are what goes out first instead of the rails (Unless the rails are not hardened). I know the rexroth are hardened rails, so you...

    Pretty much any rail 20mm or bigger has retaining clips in them, preventing the bearings from coming out when taken off the rail/temp block. When I have to take my bearings off for some reason, I...
  3. Re: Anybody buy linear rail and bearings from an amazon seller called Joomen?

    I have. Got 2 1200mm 1605 ballscews as well as 6 1200mm 20mm linear rails for my diy router. They work really well. Had to pull the bearings out and clean them (which you should do with any rails...

    Re: Cutting Raw Stock to Size on a Mill

    I don't think I will ever have the balls to use a hand held circular say like that on metal, even with a metal cutting blade.

  5. Re: modifying a lathe spindle for use as a 4th axis

    While the front bearings are most of the load that will be seen on the spindle, it's still worth the time and money to maintain the rear bearing as well. This is because it keeps the spindle steady...

    Both are great machines to learn on and upgrade later. It just depends on what type of machine you want. The C-Beam had a moving table, while the Sphinx has a moving gantry for Y. Before I had done...
  8. Re: Which CNC Router to get for a beginner with a budget

    If your looking at a learning machine, I would look into the OpenBuuld's C-Beam or Sphinx. They are much more forgiving, have a good drive system (leadscrews instead of small 5mm belts), and a lot of...

    Re: Understanding Mill Specs

    So what it's saying is you have 6 7/8" is usable travel in X and 18 7/8" in Y. In truth, it's probable 6.5" x 18.5" in travel with whatever you have on Z. The tabel size listed is just that, the...

    Tell me about it. 2.2kw Spindle, 25mm Z-Axis plates, linear rails for both X and Z, Ball-screw, and the 35mm plates for the gantry itself. And that's just the gantry.

    ES-MH234120 As Spindle Motor

    So, I have a used ES-MH234120 (12N.m torque, 1700 oz.in).

    What I'm trying to figure out is would it be worth using it as a Spindle motor on a manual mill (Being converted to CNC) in place of the...

    Re: Sieg X2 conversion about dead?

    If it is the dovetail box, then I would say put linear rails on the Z-Axis. If the manual mill is big enough, you should be able to take the column off, secure it to the big manual mill and mill the...

    Re: Recommended Voltage for DYN4 Drives/Motors

    True on all accounts. As long as the RPM isn't lower than 1000-1500 RPM, it will work well for what I need. Unless I completely re-design my whole machine, I don't think I will be maxing out the RPM...

    So, I think I am going to change to the DYN2 drives with a 750 motor. Honestly don't know if I want to run the DYN4 servo's at 120v. Was going to use either a 1000w or 1500w toroidal 70v power supply...

    Re: Recommended Voltage for DYN4 Drives/Motors

    I was wondering that as well. If it does, the CNC is on it's own 120v, 25A breaker. So if the amps are double, the breaker will handle and still have about 25% over-head room just in case.

    Ok. So that's not bad at all. I had calculated the max speed (@3000rpm) to roughly 500ipm, and knew I would never be able to get that on my home machine.

    I was not expecting to go over 1000rpm on...

    If you ever decide to get rid of the 400w servos, hit me up or post them in the classified section. I had just started looking around for servos to upgrade my machine from steppers.
