  • MicroMark and other micro Mills

    Does anyone on the list own one? And would be willing to share their fortunes or mis-fortunes with us?

    I have a harborfreight Micro Mill. It works nicely for the 265$ I payed for it. Cant drill 1/2 holes or use 1/2 end mills with it though, I tried, hehe.
    With that said, I must say, I wish I had a bigger mill.

      Hi Al
      I have the Harbor Freight Micro Mill.
      I Made an adaptor and installed the motor
      feed that is made for the Mini mill on it.
      I make telescope mounts for air pistols and
      other small things with it. I like it fine.
      However I would like to have a larger mill.
      I have the micro and a Unimat SL1000 that
      has a very small milling capability.
      I bought the motorized feed from "Little Machine Shop" for 149.00 and it has variable
      speed.

        One other thing "Little Machine Shop" has all the spare parts for the micro mill.

          I have a Derbyshire Micromill and it's built like a brick @#^*house. It's tough to find parts for though. All in all, it's a great little machine.

            I've done milling on my Unimat DB-200 for years. Same comments about limited size but I have used a 1/2" end mill. Mounted it in the 3 jaw and used it like you would a fly cutter in a larger mill. But slow going with very small depth of cut and slow feed rate. Takes hours to do what can be done in minutes on a full size mill.

            Glad I now have a bigger one.

            Make it fit.

              Yeah, I know! I'd love to have a Clausing or a Benchmaster, but, they are scarcer than hens' teeth! A big Bridgeport like I trained on would be better, but is too tall for the Basement ceiling, so I am going to have to go with not only what I can afford but what I can find room for in the Shop. Thanks for the info. Is there a "Group" for these mini mills like there is for lathes and shapers, etc?

                My HF micro mill drill is the first machine tool I started out with so I don't have anything to compare it with, but I would like to say I am very pleased with it, first of all I like it's small size because my workbench is in my bedroom, the bench is 19" by 6 ft. and my mill shares a spot with my HF mini lathe, and bench top drill press. Second I love the variable speed where you can change the speed on the fly, third the square column is excellent, I am constantly drilling with a center bit raising the head and inserting the drill bit, as well as changing cutters and everything else I constantly raising and lowering the mill head, it also has a nice micro feed handwheel in the front, for depth of cut in the .002" per line, however after using that for a long time I decided I could get better accuracy by tightening up the quill and using an dial ind. with a magnetic base on the back of the column , raise the whole mill head up and down wathcing the indicator.
                The table on my last years model locks the X,Y axis with a center position metric hex head screw. I got tired of using an allen wrench to lock and unlock the table, cause I lock and unlock the table quite often during milling operations. So I bought a couple large lenghth hex screws, and mathcing metric hex keys and made small knobs on my
                lathe, then I cut the hex keys into small pieces then I glued and pressed fit the hex keys into a hole inside the knobs and glued and pressed fit the hex screw into the knob into the hex key, so now the knob has the screw built right in and makes it easy to lock and unlock the table on the fly. The weight og the machine is around 100 lbs. or so so pretty rigid for alot of small milling operations, my model came with a 3/8" chuck, I have used a 1/2 cutter with a reduced shank, and I found with the proper feed and speed I was able to mill with it pretty easy, as long as the bit is sharp.
                With a sharp 3/8" roughing end mill I cut slots, 1/2" deep in one pass in aluminum bar stock, again I find the proper feed and speed and then I have hardly any vibration at all.
                With a little bit of finangling I can fit a 6" rotary table on it.
                Now again feed rate will be considerably slower than you would with bigger models.
                But I am well pleased with mine, but than again that's the only mill I ever owned, so this is kind of a biased opinion because I have nothing to compare it with.

                Here is a project I'm still working on, it's a cross slide table made out of aluminum for my drill press. I only have the two slde mechanisms done so far, but to give an example of size of projects that can be done take a look, this is all done on my micro mill drill. These are dovetail slides.
                The one I was able to cut dovetail length of 7 inchs. all made from 1/2" X 3" aluminum bar stock.

                  I have Micro-Mark's version,(mini-mill) my first, so nothing to compare it with.
                  Does the job, just go slow,no deep cuts.
                  Today I milled a slot with a 1/16" end mill, figure that would be difficult w/a Gonzo B'port.
                  The M-M has MT-3 collets, might be better to get one of the other names, them it will have R-8.
                  I realize its limitations, don't force it, and am happy w/it.

                    Thanks, everyone!

                    dvk, looks to me like you're doing O.K. with that job. Nice work!

                    PSD KEN The MT-3 tooling would suit me just fine 'cause I have made quiet a bit to fit my lathe which also has a MT-3 spindle socket.

                    I am currently working on a live steam locomotive and I am looking for something with which to accurately lay-out, drill, ream, and flute the side rods and mill the other assorted parts. I'm getting a crick in my back from bending over so far to see what is going on while milling in the lathe!

                      Al, If I was you, I'd go over to http://www.lathemaster.com and take a serious look at his Square Column Mill drill. He is a small buisness, and never has many tools in stock, but people seam to like his service.

                        THANKS, Bill H.! That is one hefty little machine and just may be exactly what I am looking for. Thanks for telling me about the site as I had not picked it up in any of the micro machine links.

                            I am very close to getting the mill from Lathemaster, but I'm having trouble getting over the $400 shipping fee he wants. I really don't have room, but it looks like such a nice unit I would find space for it. Still, $400 where most others charge $125 for a similar size and weight item is hard to swallow.

                              I agree with George - nice work - keep it up laddy!

                              George get a grip,man! You know that if she let you do that the next thing she would do is "arrange them" for you beibg the good helpful wife she is, would not realize that in a man's world chaos is in fact - "Highly organized Structure" and messing with your stuff she disturbed the nature of things and you would never find anything again... poor George.
