MICRO Mill MF 70, 37110

Great Mini Mill. You aren't going to machine an engine block with this, there is very limited height adjustment. But this machine is sturdy, stable and reliable. I've used it to machine stainless steel, brass and Delrin so far, in our prototyping lab. It's a great value. Picture below is a concept controller I made using this. I machined the cord grip hole and radius in the 1/8" stainless bar with this bar, and hollowed out the Delrin rod for the switches and electronics.

From Cutting the box open, to milling my first cut All inside One Hour. that would have been CUT in Half, if MORE INSTRUCTIONS were provided in the "Instruction Manual" !!! What would I change in Instructions? Only add that to Assemble the XY Table to the base, Crank the Y AXIS All the way IN (TO the Column) or OUT (AWAY from the Column) to insert the 4 cap head screws !!! Yes, that ~is~ a minor thing, but I had not drank my morning Coffee !!! My First Milling was upon a piece of Ba!tic Birch Plywood, which will be a "sacrificial surface" for other milling jobs. It was installed over the center t-slot only, as it was just scrap plywood. I have a dust prevention plywood custom fitting to the left & right of my Proxxon Precision Vise which arrived three days before the mill :-) I am pairing the Mill with a Proxxon 150 Lathe, arriving "soon". All told I now own 6 Proxxon tools, including their engraving equipment. Great Tools, Great Designs, just needs a ~bit more~ Instructions in my opinion.⁷

This is a fine entry level machine, a good value, designed for light work. It met those expectations and has fulfilled my needs mostly. It reliably chews out material but at a slow pace because it is a small machine. It is made in Europe, not Asia, which is a big plus to me. One might expect high precision in a small machine but that is a bit unrealistic given the price point. My only criticism of the function is the play in the table is a bit excessive, but that likely could be adjusted. It doesn’t appear to be slop in the manufacturing; I have just been too lazy to attempt to tighten the table and haven’t needed that precision for the work I have done to this point.

I read the reviews prior to purchase. Accurate and durability were excellent in the reviews and also number one with me. One should also purchase the drill chuck as precise holes are important when working on small hobby parts.

Excelent mini mill for cutting RC carbon fiber that is 2.5mm thick. Really does extremely accurate parts up to 0.10mm accuracy and is not that loud (Even when running at 20,000rpm). Super easy to use and the stock clamps work great at holding the parts. You will likely need a HEPA vaccum and a mini cnc spoil board to not damage the xy-stage. It's pretty great value if you are into prototyping small parts quickly at a home workshop. Just make sure to get RC specific metric mill bits with shanks of aprox 3mm and carbon fiber cutting bits from 1.5mm to 3.0mm for best results.

Unfortunately for my needs this was just way too small. I wanted to be able to use it, the price was so good. But it's really tiny.

If you buy one of these looking for an advanced Dremel you will be very happy. If you're looking for a mini Bridgeport, you may be a bit disappointed. The Proxxon MF-70 combines the utility of a Dremel with the precision of a mill. With it you'll be able to perform many operations that would be difficult or impossible holding the Dremel in your hand. Before I decided on the MF-70, I considered cobbling together a mill from a Dremel 220-01 stand and a HF X-Y vise but the Dremel stand is crap and HF X-Y vises seemed expensive and crude. I also considered getting a Vanda-Lay ACRA rig, but when you add in the cost of the adjustable X and Z axes it approaches the cost of the MF-70, and you have to add your own Dremel. In my case the MF-70 was not the cheapest option but so far it's been fun to have in the shop, and it has a lot of support if you want to go CNC. BTW I recommend picking up the 24260 precision vise, it complements the mill nicely. On the downside, the most disappointing aspect of the MF70 is that when cranking the X axis, the table deflects +/- 0.010". That's 20 thousandths total error. Using a twisting grip on the wheel rather than cranking the handle helps reduce this to a few thousandths. Tightening the gibs helps, however the motion then becomes "grabby." The Z axis scale ring hangs up sometimes which throws it off zero and causes errors. I also wish the head rotated since it would be useful to position the spindle horizontally at times. Another review mentions the Z axis has a lot of play or backlash. Most likely the problem is that the Z axis stop nut was set too loosely at the factory. Here's the fix: You'll need a 2.5mm allen wrench and a deep 10mm socket. Remove the four allen bolts on the top cover of the Z pillar, unscrew the Z leadscrew from the spindle nut, and remove the top assembly from the mill. Slip the 10mm socket over the leadscrew and tighten the nylock stop nut under the cover (it's left hand threaded so tighten to the left). Lightly snug the nut then back it off a bit so there's minimal axial play and the handwheel turns freely. Reassemble and test. The Z axis will be much tighter. UPDATE: After less than a month, and used only on weekends, the motor died. It was running fine when it went "POP", the GFCI it was plugged into tripped, and that was that. It's currently at the Proxxon repair center in NC. This is very disappointing considering I've had a Dremel for years and it's taken a beating and still runs strong. Apparently the handheld Proxxon unit also suffers from these types of failures. This review has dropped a star and will be updated after my repair experience. UPDATE 2: Prox-tech repaired the unit and it's running again. The motor and controller board were replaced. This motor is noisier than the original, similar to what other reviewers have noted, but it is tight with no excessive play as far as I can tell. Turnaround time for the repair was ~2 weeks not including shipping. Since I'm wary the motor is going to die again I've been running it at lower speeds, well off max, and it seems to be running cooler. I hope it continues to run for years because it's still a great little device and fun to use.

Very nice

Efectivamente hay un error en la publicación, las medidas en pulgadas están correctas, pero no las métricas, yo la compré sabiendo que Proxxon es una marca más bien para hobby, y me gusto mucho. No, no es industrial ni mucho menos.

On peut facilement faire de la sculture sur bois avec cette machine. Le bois est le matériel idéal pour apprendre à bien manipuler la machine. Une fois que l'on sait, on peut passer à l'aluminium, le cuivre et à la fin, le fer. C'est une machine bien imaginé pour le petit bricolage. Elle complète bien l'atelier de menuiserie de papa.

worked well but burnt out fast

Excelente maquina, aun cuando vibra un poco, el maneral de velocidades, no se siente muy firme, el desempeño es excelente, lo compre para trabajos de modelismo y caseros, me funciona perfectamente bien, los materiales de muy buena calidad, de metal y suave para manejarlo. Lo recomiendo ampliamente.
