Drehen mit der Unimat Part 1

Für diejenigen, die es interessiert mal ein bisschen Dreherei mit der Emco. In diesem Video wird das Gewinde einer alten M20 Schraube abgedreht, sodass es als Rundstahl verwendet werden kann (Rundmetall kaufen ist mir zu teuer :D)
Viel Spaß damit!

Hi Kevin. Thanks for the nice comment, and yes indeed it seems like a giant screw on the Emco :D Will be probably the largest thing I will ever turn on this lathe... But I had it lying around and nothing to screw onto so I decided it to use this way. I will make one more video showing turning between centers (again an old screw) and using the milling option of the SL. Then I will finish the "Emco-Series" - I don't want to bore my subscribers :D Greetings Adrian

Hi Adrian Don't stop making videos with the unimat, when I said let it have a good rest I tried to say let it have good sleep after such hard work :) I think you should show all the operations that it can perform. Greetings Kevin

[@AstraWerke]

Hi Kevin Yes, I got it like that - but for people which aren't experienced in turning etc get bored if there is "Unimat Part 1, Part 2, ..." So I try to compress things... The circular saw, the coping saw, and the grinding machine are too slow/ not strong enough for use with metal... Thus, the Grinding Stone-Dust will ruin the precision parts due to its abrasive influence... But the saws are okay for wood. So I'll be showing it as a mill and some additional stuff with the lathe. Greetings Adrian

[@scheppach69]

Hi Adrian That M20 screw looks massive in your Emco lathe ;) but it seems to cope quite easily with the task you gave it! I hope you will now let it have a good rest :D Good choice of music, great production, keep up the good work! Greetings Kevin

[@AstraWerke]

Yes, it is one of the smallest lathes available (apart from those for watchmakers) But it has all the equipment (will upload a video from it as a mill soon - if you are interested), you can turn between centers, it has a steady rest, 4 jaw chuck, and all that - the only thing it doesn't have is an automatic feed and quick-change box - but for those sizes,dies will work fine... and you need a good trained arm :-) Greetings Adrian

[@AstraWerke]

OK, I wish you good luck for the purchase, hope you will get it! It is a very nice machine if you know her limits. The largest diameter with the jaws mounted like in this clip is 25mm (thats shown in the clip BTW - the jaws were about 2mm away from hitting the ways), with the jaws inverted you can go up to 50mm. All the best Adrian

Hi there, thanks for the subscription! 150 € is a good price for the Unimat - what kinds of accessory comes with it? Things you should look for are spair belts as the original ones tend to snap quite quickly, but you can buy a length of belting via Ebay, you can simply cut the desired length off and melt it together, that holds forever. Else, of course the bearings should be OK and the slide should not have play, but when you clean it after every use, you've got a tool forever! Cheers Adrian

[@KeithFenner]

Thanks Adrian for the tag on the link for your video, that has got to be the smallst lathe I have ever seen, someone working. ;{)-----

[@valic000]

Hey Keith.You have great vids.love to watch,how creative you are.I have a Lorch,a big watchmaker lathe,and a smal Emco 3 unimat too,but you wil be amazed,what you can do with it.almost anything,only two rules! must be smal,and no rush :-) I make pistons for my model engines,very accurate to a 5/1000 of a mm. Miniature conrods for model diesel engines with 1 cc volume etc..Runing engines ofcourse! Keep posting your work a lot inspiration for a lot peopel! regards from the NetherlandsI Peter

[@ClassicCarSpotter]

Thanks for the reply, it really helps! Concerning the accesories I have no idea if he has something extra than the base setup in the photos. I still haven't talked to the guy, he's 50km from my town so if I go to see it I will probably buy it. Thanks again, if I get it I'll let you know :)

Ich habe heute noch mal etwas experimentiert - wenn das Lager warm wird, dann läuft es viel leichter! Nimmt jetzt so gut wie kein Power mehr weg :-) Gruß Adrian

[@AstraWerke]

Hallo Peter. No need for english - nederlands is ook mooi :D Das Problem mit der Reduktion ist, dass die Riemen und Lager relativ viel Widerstand haben, und dadurch der Motor weniger Kraft hat und schneller heiß wird... Aber ich werde es mal probieren, okay? Gruß Adrian

[@valic000]

Dann solltest du checken,ob alles frei dreht,alle lagerstellen nicht abgenuetzt sind,und eventuel PTF schmiermittel ( +teflon) benuetzen.Das reduziert sehr gut reibung. Groetjes

[@valic000]

Ich denke alles was schmiert ist oke.Nur halt sorgen,dass die riemen nicht fett werden....sonst hast du keinen antrieb! :-)

[@valic000]

amazing what a smal machine can do! you shoud reduce the speed Adrian,the diameter is too big,and its steel.With half the speed and maeby moore power when you use reductions,wil cut far better,but as final last cut,high speed is good! Keep doing experiments and learn..like I learn also when I was at your age and m first smal lathe! :-) Tot ziens mennertje! Regards P&P

[@valic000]

Ja,ist gut denkbar.Hast du nicht mit der hand erst mal gefuehlt,wie schwer sie drehen? Aber wichtig ist ja,das es nun oke ist!

[@PatrickN487]

Hallo, schauen wirklich sehr schön aus die 3 Videos. Überlege auch mir so eine Drehmaschine zuzulegen. Für den Modellbau ist sie ja Ideal, gerade wenn man Knunststoff, Alu und Messing bearbeiten will. In welcher Preisklasse liegt die Drehmaschine und weißt du auch was das Zubehör so kostet? Insbesondere zum Fräsen? Danke für deine Antwort

[@valic000]

Oke,das kann sein.Dann wird das oel duenner,und es dreht leichter.Denke aber das da irgendwas etwas noch anlief,und jetzt freigekommen ist..Schoen,das es immer besser geht!! Gruesse P&P

[@AstraWerke]

Das kann sein, dass die "Werksschmierung" ein bisschen verharzt war - die Lager haben ja Jahre bei Bernhard rumgelegen...

[@ClassicCarSpotter]

One more thing, what's the largest diameter of material I can work with on this lathe?

[@ClassicCarSpotter]

Hey Adrian, I like your videos and I subbed :) I'm looking to buy a mini lathe, but here in Macedonia so far I only found Einhell MTB3000 but it's out of my budget (here it cost 650 euros). However, I found a second hand Unimat Emco SL 1000, so should I get it? The guy is asking 150 euros, what do you think? Is it expensive? What shoul I be careful about when looking it? Thanks!

[@scheppach69]

Oh yes I agree the price of steel at the moment is ridiculous!!!!!!!!

[@AstraWerke]

Das ist ja das komische - die Lager sind ja alle brandneu! Vielleicht ist das Schmierfett zu dick? Würde da auch normales Auto-Öl gehen? Gruß

[@PatrickN487]

Hallo Adrian, Ich danke dir für deine Antwort. Gut das ist erstmal eine Hausnummer und da weiß ich bescheid was ich an Geld sparen muss. Vielleicht finde ich ja auch noch eine andere Maschine die für meine Zwecke reichen würden. Da ich ja Hauptsächlich Kunststoff bearbeite und ganz selten mal Messing und Alu.

[@AstraWerke]

Hallo! Meine Maschine hat mit dem ganzen Zubehör 380 Euro gekostet, man muss aber immer ein bisschen warten - leider ist die Unimat auch ein Sammlerobjekt und dementsprechend teuer. Am billigsten sind meistens die Maschinen mit Zubehör (wie bei meiner Maschine), sonst zahlt man sich mit dem ganzen Zubehör dumm und dämlich. Also einfach ein bisschen abwarten, irgendwann kommt dann was rund um 400 Euro. Gruß Adrian

[@silly800ify]

How many inches is chuck? And how many watts is motor?

[@AstraWerke]

The Chuck is right around 2", the Motor pulls about 60 Watt, later Models had 80.

[@silly800ify]

@@AstraWerke thanks for the info! I just bought an sl db 200 and its really cool ! I just wanted to see what im able to turn on it .

[@AstraWerke]

@@silly800ify I strongly suggest mounting a stronger Motor, the machine is rigid enough for alot more than the original motor is able to pull

[@silly800ify]

@@AstraWerke thank you so much man I appreciate all the help. Because it seems well-built so I was hoping to do a little bit more than just really small pieces so thank you for the tip

[@AstraWerke]

@@silly800ify No Problem. The Unimat was my only lathe for a long time and whilst some jobs took their time its never let me down.

[@AstraWerke]

Nein, hatte vertraut, dass sie perfekt gehen, wenn sie neu sind - einfach eingesetzt, Fett rein, Rolle drauf und fertig eeehhh...
