    I picked up a MAHO 400E

    Hi guys,

    I bought a MAHO 400E with a personality problem. Picked it up on Sunday.

    It will be a challenge to try and get the electronics working again, but the mechanical condition is near new. I have been considering doing some sort of CNC mill conversion, but couldnt face spending the money and time on either converting my Deckel G1L into an FP0NC, or paying 2K fo a chinese RF45, and tossing everything but the main castings.

    Bit of a challenge getting it in there. The machine shop is actually the room behind the garage, but the door I only 70cm wide. I'd have to remove the huge control cabinet, the Y-axis ram and the X-axis to fit the Maho through there. I think it is going to remain in the garage now.

    X 400mm
    Y 250mm
    Z 350mm.

    Although right now zero, until I can get the brain going again. Very rigid machine, it weighs 1400kg. The ball screws are about 50mm diameter

    Everything about this machine is pretty massively built. The arm that the user module swings on must weigh 40kg. I figured for only a few hundred € more than an RF45, this way I get ball screws, glass scale feedback, automatic way oiling, a swarf enclosure, 18 spindle speeds from 40-4000rpm through a 9 speed gearbox and 2 speed motor, and German iron. If the Phillips control is not salvageable I'll still be miles ahead on a retrofit to LinuxCNC even if integrating the gearbox in the ladder control is not trivial.

    This is the X ballscrew.

    Hopefully you can get it up and running quickly. My conversion just keeps dragging along...

    I got a Maho 700 a few years ago with Philips 432-10. Took a while to get it running, first me not knowing I had phase not correct then going through hundreds of parameters. When finished it was running better than new as everything was working well even gear changes. You can see where previous owners had been changing gears with a wrench. As I was learning the machine I extended Z axis near maximum. When I sent all axis to home it overtraveled Z because wire to limit switch got caught on cover. The only cover I hadn't taken off when getting machine ready. I have lots of documentation, manuals and wiring schematics but none on reassymbling Z ballscrew. I think you should try and make it run as is first.

    Thanks for posting, I need to get mine fixed.
