    Proxxon Micro Bandsaw - WHAT?!?!?

    Post by Ivo on Wed Apr 25, 2012 5:00 pm

    Been looking at some metal bandsaws on the net...was on the verge of buying it, but in the last minute some unexpected expenses popped up (things break and need repair Rolling Eyes ) and once again I'm back to ~ "can't afford it".

    Either way, I thought it was a nice find and I thought I'd share it with you guys and hear your thoughts.










    http://www.amazon.com/gp/product/B001D6PJAQ/ref=olp_product_details?ie=UTF8&me=&seller=
    Proxxon Micro-Bandsaw MBS/E


    After a recent experience with a Chinese made
    product, it is indeed a great pleasure to examine and report upon a
    Proxxon machine. This machine is the Proxxon MICRO bandsaw, MBS/E. I emphasize the word micro so there is no delusion on what this product represents.

    I have a small metal cutting bandsaw from Lathemaster and also the extremely popular Delta 14" woodworkers bandsaw. The MBS/E
    saw fits a different purpose altogether so therefore stands in a class
    of its own. If you are a hobbyist model builder, this is an absolute must for your workshop.

    I like bandsaws probably better that any other
    kind of saw. Of course there are limitations, as they can not do inside
    cuts. But I like the fact that the blade is always traveling in the
    cutting direction, no lost motion. I also like that the blade's cutting
    force is down against the table and not kicking back like a rotary saw. I
    feel safe getting my fingers close to the blade but of course realize the danger.

    This saw with it's variable speed (395 to 820
    Ft/Min) is perfect for cutting sheet stock, tubes, small bars from out
    of almost any material a model builder chooses with which to work. I
    have already cut some sheet brass and steel with little to no effort. The saw does the work.



    This is the saw out of the box without the table
    installed. I immediately noticed some slight changes from the pictures
    supplied by the manufacturer. The main switch is now a heavy duty toggle rather than a push button magnetic switch. The blade guides are now the ball bearing version
    which used to be extra cost. I ordered a pair, now extra, as I was
    going to install the better guides anyway. Nice that it is now standard.
    This is the rest of the parts in the box except for the 24 TPI blade on the right
    that I ordered extra. The standard installed blade is 14 TPI. The is
    also a narrower depth special temper 14 TPI blade available as well as a
    diamond blade. The diamond blade requires the water cooling kit and
    will add an additional $185 or so to the cost of the saw.




    This is a speed selection recommendation chart. It is mostly all yellow so I don't see it as much value. The speed control is not linear, at least from the motor sounds. The speed control is more logarithmic than linear. That could be intentional design due to the built in speed compensation mentioned in the manual.
    An overall look inside the case. The wheel diameters are slightly over 6 inch.
    The dark green case is die-cast aluminum. Plenty rigid for this
    purpose. The yellow front is plastic and is chained to the rear case
    near the center.


    Here is an unexpected feature. The bottom wheel has a brush that scrubs the tire of debris. Note the wonderful looking die cast and machined wheel. There are two ball bearings per wheel. One on each side.
    Here you can see the big (red) main switch with
    removable lock pin (yellow). The black knob to the right is the speed
    control. There appears to be plenty of adjustment to the motor for belt tension.


    The upper wheel is as impressive looking as the
    bottom one. Two ball bearings here also. The tires on both wheels is
    some sort of plastic/rubber and can be replaced if/when needed.
    The axle plate on the bottom is bolted on with
    three screws. Again, a very good looking part. You will have another
    look further down in this series.


    Both the top and bottom tires have a
    flange on the rear edge that prevents the saw blade from slipping off
    the back of the tire. That is a good idea as that is the direction the
    blade is pushed when making a cut. The blade could be pushed off the
    wheel if the blade guide bearing is not properly adjusted.
    The top knob is blade tension adjustment. The middle knob locks the blade tension and has some effect on tracking. (More on tracking later.) The bottom left knob is the adjustment lock for the blade guide


    The back of the saw. The motor and speed
    controller is completely covered. The ventilation slots are fake. The
    black tube on the bottom left is the vacuum connection. The three black bolts are the bottom wheel shaft mounting.
    The machine label indicates the motor is 110-120 volt 60 Hz and 1/8 HP. This is entirely adequate
    for the size and purpose of this small light duty saw. I have
    deliberately stalled (tested) the blade and motor with overly aggressive
    feeds in brass with no harm. Just let the blade and motor do their
    work. There is not a lot of rotational mass (momentum) in a tool of this
    size to overcome heavy feeds.


    With the cover open it can be seen that the bandsaw is not very wide. The base is in fact too narrow
    front to back. The product manual recommends the saw be screwed to a
    bench or a wider base. I am going to make a wood base extending as wide
    as the motor both rear and front.
    This is another unexpected cool feature. The four front cover bolts are captive. No loosing these bolts when the cover is removed.


    This is the die cast table. Talk about polish!
    The coolant trough is cast in but looks machined. The T-slot (yes,
    T-slot) IS machined in. The center is a replaceable plastic part.
    Another step of quality. The saw blade entrance slot is bolted to maintain alignment.


    The bottom of the table looks as nice (without
    polish) as the top. Look at the hefty mounting/angle plate. The taped
    holes in opposite corners are for the water exit from the coolant trough on the other side. Extra parts are provided in the optional water cooling kit.
    Simple design but the table locks very secure.

    Just another look under the table. The saw blade enters the cover here.
    I don't know how warm the motor may become. This kind of band sawing is not usually heavy duty or long term.


    Here is the new blade package. Several 42 inch blades are available including a diamond blade that requires the water cooling kit.
    This is the triple ball bearing blade guide. It was installed on my test machine so it must now be standard.


    A miter gage is provided with the saw. Another quality detail is the T-Slot in the table. Quality IS in the details.
    I set the table angle with the precision square.
    The center insert is a bit too low and the table edge will snag small
    parts. This insert could be be shimmed or a new insert (brass?) made. If
    you don't intend to angle the table the slot could be much more narrow.


    Another overall look at the saw. This time with the table mounted.
    Close up of the vacuum port. The tube to the left is soft rubber and is (I assume) some sort of adapter for the vacuum hose.


    Here is the top blade tension adjuster. I noticed the two hex screws at the top function as tracking adjustment by tipping the plate at the top.
    Here is another look at the bottom wheel. Note the rim on which the belt drives, has no teeth. The toothed belt runs like a flat belt. This may provide some motor / controller protection from a jammed saw blade.

    In the bottom right corner is a little slide that can be removed to let the chips fall out if the vacuum port is not used


    I examined the adjustment plate and added some more thread locker to the tracking screws. I could see there was already some on the threads.
    I adjusted the tracking until I got the blade to
    track where you see here, just off the rear flange of the tire. It
    required about one turn on both screws. This provided improvement from out-of-the-box running.


    It can be seen that I have been cutting some brass before this picture. This is the 24 TPI blade.
    This brass barb is where the water connects if the user desires water cooling on the blade.


    The blades are claimed to have very long life
    and it can be seen in their design that the teeth set and built in wave
    set are designed to provide very good kerf and cut tracking.
    I am measuring the throat. Book says 5 29/32 (150MM)...


    ... but I have some extra space at this end. Overall available head The total machine is height is a little over three inches.


    The overall machine is about 19 inches with the knob
    The overall width at just the base is 12 inches.

    The saw runs quietly like my Delta wood bandsaw.
    You know it is running but the noise is not loud or objectionable. The
    gentle sound can make you lower your guard.

    Cutting metal of course still makes some noise. Ear protection
    is recommended as well as eye protection. As small as this machine is...
    it is still a power tool and there are certain inherent risks. It is
    not a toy saw to be given to a young child without supervision.

    The quality I saw (and show here) will make this a favorite
    tool for anyone who uses it. It will also last a long time as it is not a
    minimal built product.
    The space in front of the blade is almost 4 inches.
    This saw is not designed to be a
    competitor with full size band saws. Don't buy this one if you have full
    size work to be done. If the need is to cut small parts from thin
    materials then this saw will do it quickly and with style.

    My intention at THMS is to use it for cutting small steel,
    brass and aluminum parts for use in my machining projects and metal
    constructed models. This is a must have tool for anyone building scale
    models from real life materials. Small scale live steamers, scale boat
    builders, doll house details come to mind. This saw is a "big brother"
    companion for the type of work done with a scroll saw as it has a larger
    blade. It works best for less detailed and straighter cuts.

    Update: I have installed the Proxxon bimetal
    blade and have found this saw to be an excellent tool for cutting metal
    for use on my A3 Locomotive project as well as any other metal parts I
    have tried. The blade is the most expensive of the blade selection, but
    makes the MBS/E saw a true metal cutting miniature bandsaw for the
    machine shop.

    It will cut thin (1/8" -1/4") wood with little problem. Thick
    (3/4") very soft wood such as basswood or balsa tends (in my experiance)
    to load up the fine teeth on the 14 TPI blade and such use is not
    recomended by me for this saw. A 6 or 7 TPI skip tooth or raker blade
    would be a better choice for sawing soft wood, but is not supplied by
    Proxxon.

    The blade length is 42" and is smaller than (say) the Delta
    blades. I haven't yet found a second source for 42" blades. However, the
    Proxxon blades seem high quality and should provide long life in hobby
    type service.

    Bottom line the Proxxon MBS/E is a very good micro bandsaw. It gets high marks from THMS. Stop drooling all over your keyboard and go order one.

    $300 for a bandsaw this cute...hmmmmm scratch ...I kinda like it. cyclops

    Since the work we do does not require brutality of heavy machinery 90% of the time, so this might just fit the bill. I heard a lot of good things about Proxxon guys, if you guys also have something to say, I'd be delighted to hear your thoughts (perhaps even your own quick reviews of this or similar saw)...

    As much as I love my Nicholson hacksaw,



    ...sometimes I just want to buzz through something using a nice straight fence,



    ...know what I mean? Very Happy

    Hi Ivo,
    Proxxon sure makes a nice piece of kit, I do not have the bandsaw but used my other proxxon toole firly heavily and so far they held up fine. I dont know if they produce n china todays as most manufacturers do but the quality is better than the usual china crap out there.
    As for the Bandsaw, if you will get happy with one of these mainly depends on what you would want to use it for.




    Forget about cutting steel with this machine.


    I guess it will struggle with thicker brass,bronze, ally too and dull far quicker than anticipated.
    At first, the lowest band speed setting (band speed for this machine is between 180-330m/min) is still far too high for effectively cutting steel. Depending on the kind of steel (mild, tool, stainless etc.) cutting speeds of 15-75m/min are recommended.
    At second there is no bi-metal blade avaliable, trying to cut some steel at too high speed with an unsuited blade will dull your blade very quickly.
    If you have a light duty of cutting wood, plastics and thinner non-ferrous in mind I would say go for it: As far as I know there is no good alround bandsaw on the market that covers cutting speeds from 15-850m/min. You can have one for either metal or wood but not a one-in-all.

    Thanks for the input, yes I'm only thinking about cutting things in the 16-14 Ga range...and occasionally thicker pieces, but only small cuts in difficult areas and with coolant/cutting fluid.

    As far the bimetal blade...yeh, that's one thing I overlooked, but perhaps there are blades available for other saws that match the size or can be cut, shortened, and welded for use with this saw? I think my neighbor has some experience with welding badsaw blades...might need to bring that up next I talk to that crazy biker (went to buy beer). Laughing
