EMCO UNIMAT 3
JOB DONE MAN!!
I have a medium size lathe but it is a nightmare to work on small parts as M3 -M4 screws or small pins and axles.... so, I had the chance of getting an Original EMCO UNIMAT 3 lathe,made in austria...
here we are.. from my dad to his son (myself) , the unimat is changing his dad which is me now!!
As anything that comes into my lab I need to disassemble parts off to fix problems and improve fitness of my machines!!
The emco is really well made, I never had chance to work on an original one before and I am pleased to be an EMCO dad (owner) now...
check out my emco just before cleaning and servicing...
I got many accessories as... 4 jaws independent chuck, extra 3 jaws chuck with reversed jaws, two face plates with dogs, tailstock drill chuck and more....
I will make a miniaturiZE ALGRA toolpost for this miniaturiZED jewel (emco unimat , I mean)...
also I will install a YADRO computer based DRO system to make this lathe the coolest on the planet!!
stay tuned!!
work work work.....
more work...
all disassembled now .....
the headstock is equipped with 6003 ( 17 * 25 * 10) bearings, they are not tapered but there is a elastic watchers system that makes the bearing close as tapered ones.... the runout should be zero or so.....
bedways sanded down with 2000 grit paper and any part cleaned and serviced.
in this photo I am mounting back the carriage 4 gib screws, using some medium strength loctite, to improve jibs stability...
During the inspection of the motor I felt a bad NOISE and I discovered then that one of the bronze bearings was worn!!!
I had to machine a new bronze , I fount an old bronze in the scrap box...which was bigger but with a 7.00 mm bore, so first step was to drill (mill) a 8.00 true bore, and then make it tall at 10.00 mm.... (showed).
next step is to make it same external size as the original bronze....on the lathe (the big lathe save the son lathe!!)
a small touch on the lathe for the motor axle which was out of 0.05 on the left end....
all mounted now and perfectly working!!! smooth ride at 5000 rpm!!!!
tool post, that will be replaced soon with a MINIATURIZED algra toolpost (AKA Dicksons style turret ..)
4000 RPM ??? I can't think to machine something so fast!!!! good range anyway 130 to 4000
tailstock with dead center (I will make a live center soon...)
do you wanna turn between centers? you can do it with the UNIMAT 3!!!!
update april 2007:
I have built a small lathe box with dip tray on top, to hold all parts in place!
check out painting step....
material is layered wood, 10mm thick.
this is the complete result, I have installed a neon lamp also.
the lathe is held in place by 2 M4 screws..which hold also the dip tray!
