    Surface grinders are great at getting really fine finished, flat, and true surfaces. The applications that you have described would fit well, if the parts fit. With the correct tooling, rotary table / dividing head, you could also sharpen end mills and make some very precise lathe tools.

    A surface grinder can be a very useful tool, with many different applications.

    You can make your own parallels, 1-2-3 blocks, vee blocks, and any number of your own really, really flat precise tools. And they can be hardened prior to the final grinding, which is an advantage.

    What brand is it? I got mine a while back because a friend had it for sale and really wanted me to get it. At the time I was hesitant since it is a huge machine and my shop is very small. But since getting I don't know how I lived without it. There are lots of things in my shop with a flat ground finish now. Most of them just because I could. :) I love my surface grinder. Post pictures if you get it. Surface grinding is one area that I could find very little help files/videos online about. Lucky the friend that sold it to me ran one for years as a tool and die guy so he has been my question and answer guy. I still don't know enough to be helpful to others just enough to get me in trouble.

    I used them to resharpen Die sections and any part surface that needs to be ground flat and smooth. If you get one it a good idea to grind the surface of the mag chuck once awhile.

    The grinder Is a Harig 612 i don't recall the brand of chuck but every thing looks and appears to be in good shapeOMG I just checked eBay and prices range from about 1800-4500 so 750 seems like a smokin deal

    They are a tool which I didn't think would be used very often. I purchased one because an offer came along at the right price. Now, I don't think I could do without one. It's used on most of my personal projects anytime flat precision surfaces are needed. Mills make things somewhat flat -the surface grinder brings it home.

    Jump on it you won't regret it. Just remove the table to transport it.

    SG's tend to be particularly heavy and deceivingly top-heavy. Please be careful.

    When I moved mine, the seller had a fork lift. The tailgate of the truck was removed, the unit lifted straight up and level to the bed and 4 guys tipped it over and laid it on it's back. We went this route because we had to travel 75 miles and we didn't feel it was safe to take the ride with it upright in the bed. Upon getting home, there was no forklift so, for 75 bucks, I called a towing wrecker and in 2 minutes, it was gently lifted out of the bed, onto the ground atop a piece of plywood and gently pushed into the garage. From there, I used pipes etc to roll it to it's current spot -where it shall remain for as long as gravity keeps it there (-a long time).

    PS: I was non-descript about the things I use it for. Truth is, I use it on about 1/3 of my projects, many of which are documented here, too numerous to really enumerate... SG's are great. There's a real learning curve -moreso than you might think. Have a very, very healthy respect for that spinning wheel -it can hurt or kill you. Always clamp your work properly and never take off more than a thou or so at a time when using the proper wheel. They're really intended to take of 1-2 ten-thous at a time -a baby's breath.

    I had to go over 450 miles to get my Harig Super612. You don't really need to take the tables off, just lower the motor & spindle housing (not the grinding stone if its still on the grinder) on a block of wood to the table or chuck and lock the table. You should be good to go. Make sure you tie it down or separate as the top main casting is just sitting on the cabinet base, at least mine was. Check the oil pump in the rear sump to make sure it is there and works. I had to replace mine and put in a Little Giant pump, which is considerably cheaper than the original replacement (well over $400). My pump was wired 220V single phase. You can order Little Giant pumps on line for about $100 or less. I installed a Teco VFD drive to the three phase motor and it works exceptionally well!! If you do the same be sure to disable the reverse so you don't spin the grinding wheels off by accident. Also get ahold of Jim at Jdsserv@aol.com. He will be a great help with you on any questions on the grinder. He also has replacement parts if you need them.
    Good luck and enjoy the grinder.
