    Default Magerle F7 Grinder Questions

    Hey everyone, recently picked up this fine old swiss watch of a grinder for a good deal. Got it all cleaned up and am trying to get it fully functional and I was hoping someone here would be able to provide some insight into the function of the machine. The wheel dresser and auto-feed seems super trick.

    I am hoping someone will be able to tell me how to engage the manual hand wheel for cross feed. The only manual I have been able to find is one for an older machine and its missing some key pages. It seems to need a combination of lever positions to engage the nut, but I can't for the life of me figure it out.

    Any advice appreciated!

    Josh

    Any chance you can go back to the seller and find where it came from. so you might ask some questions?
    looks like a very nice machine.
    I found a seller of a manual bet the price is $95.00
    OPS that was 95 pounds, so about $120 USD.

    Appreciate the help! That is actually the manual I have, from Tony. Its for a Magerle F7, but one that is 10 years older and there are a decent amount of control differences, and it also is missing the picture that numbers the levers that it talks about, doh! So I have "lever number 5 does...." but no idea which lever is number 5.

    The seller I got it from, acquired it from a machine shop buyout of an owner that died, so unfortunately he hasn't been much help.

    The other tidbit I am really having trouble figuring out is the auto downfeed. It has a really neat mechanical system that uses an adjustable block and a limit switch with a micrometer that is tied into the dressing diamond. I understand how the system works, I think, but I believe there is an electrical problem that is causing it to not work, bad relay or something. Just hard to diagnose with not knowing much about the machine!

    I found this post:

    One of the comments describes how to engage the crossfeed nut with a lever but I cannot find that lever on my machine and wonder if it was one of the changes over the years

    This company used to have 2 Magerle crush grinders that I helped scrape years ago (40 or so, I see they still have crush grinders, so nothing to loose. They may have a manual. give them a call and ask...all they can say is no.... Cylindrical Grinding, Honing & Lapping-Circle Pines, Minnesota
