@meanfazer bonjour et bonne année 2012,pour ce qui est du degagement de l'outils je comprend parfaitement que si la vitesse ne peut etre trop elever ,mais si tu utilise 1 indicateur de retomber dn le filet (filtage au repere) tu peut debrayer ta vis mere en fin de coupe et degager l'outils sans probleme et dons avoir 1VC plus elevee quel type plaquette utilise tu profils complet ou partiels et quel type d'acier utilise tu ? bien cordialement thierry bonne continuation
@stesti79 Non sono in tizio fretta, non dovrebbe essere così critico di come gli altri lavori, ciò che funziona per una persona può non per un altro. Dopo tutto quante persone può tagliare un filo manualmente in questi giorni e solo a farlo una volta e correttamente? Mi piace fare le cose once.Without qualsiasi cazzo di bocca.
Good to see a real machinist at work! As my old metalwork teacher always said, there are three secrets to good turning: a sharp tool, the right speed and not cutting too deep on each pass.
Nice work , dont listen to the youngsters commenting on here about fast speeds and feeds thats fine for CNC machining, this is skilled manual work. Its a bit like young Mechanics, just ask them about a carburetor !!!!
i agree with popebuck. you are using carbide insert sir, not just an ordinary HSS tool bit grounded for threading operations. one factor of tool wear id inappropriate cutting conditions.
Doesn't have to speed it up, he's cutting both ways...that's speed enough. Why be in a rush to get in trouble??? Plus, it takes more talent to machine this way, CNC don't cut it when you're a small machine shop owner. Then when you computer gets infected CNC don't work...can't infect a manual engine lathe...
To all the idiots that say "speed it up" go back to your cnc toys [for machine operators] and leave a proper machinist that does not need servo motors to do his job for him alone. If he "speeded it up" how the fuck is he supposed to whip the tool out at the end of the cut????? No runout groove there, he has to whip the tool out at the same point exactly everytime, or else fuck the job up. I think it is safe to say he knows what he is doing!!!!
@caerleon87 im 16 and i screw cut at about 160rpm on a manual- u dont NEED to speed it up but it gets done alot quicker if you do, its about practicing till u can do it at a fast speed- my 'tutor' at work can do it at about 400rpm (external thread) now thats skill ;)
@ASP1NALL Hi there!! Good for you! i would have loved a lathe when I was your age, but never got one of my own for years... I screw cut at various speeds depending on whether i am threading up to a shoulder on a shaft with no "run out" groove, when i go as slow as possible!!!! [34 rpm on my lathe] If i am threading something with a run out groove, i will go a lot faster!
@ASP1NALL For example, the other day i was threading some stuff M16 about 200mm long with a runout groove about 5mm wide. I started off at 120 then speeded up to 215. M16 is a 2mm pitch though. If it was a finer pitch i could go a lot quicker i suppose, all depends on how brave you are!! What lathe you use in work? I have two, a Harrison 140, and a Voerst-alpine DA180, an unusual austrian made machine!! [Google images and you will see one] GREAT to see someone your age interested in machining!!
@caerleon87 I understand! haha I was screw cutting upto a shoulder the other day- thankfully my tutor, lowerd my RPM :) and I shall take a look at the machine model on monday- however I actually dont have my own machine, as it were, some of the machines are shared and we use them according to the job were doing.
Hi, Threading up to a shoulder is a freak out!! One thing that i do sometimes, when you are coming up to the shoulder, it is very hard to see how close you actually are to it, especially if you are using coolant. If you fix a dial gauge on a base so the plunger touches the side of the saddle, you can zero the dial where you want the thread to stop, then ignore looking at the tool, just watch the dial, and as soon as the saddle moves the dial gauge, watch it reach zero, and stop!!! Much easier!!
thanks for the back up!!!! people with opinions should at least have an idea how to do it themselves! this work ....if done manually .......is not just a case of throwing the bar in the chuck and just turning the machine on and plunge feeding the tool as fast as possible because even if you did manage to make a thread it would look like shit,there are many points in the set up procedure to remember in preparation for thread cutting,i have just got a new camera and im going make another film.
@meanfazer come on don't worry about comments man. at least we can appreciate you put a video online. if you're doing it wrong, who cares actually? in the end these are your tools and I didn't see any demonstrative tendencies in the video, so other people shouldn't worry about it. thanks for the video, man, I often look at machining videos just to catch any good and helpful tricks and go-arounds to apply them to my projects :)
Its easy to ridicule efforts of others. I get it all the time but I at least can get the job done. I'm self taught and when you get a method that works for you ,you tend to stick with it. Steve
It is easier to single point a thread if you mount your cutter up side down and run the lathe in reverse. Then you dont need to worry about crashing into the shoulder. And for crying out load speed that thing up.
I have cut may threads on a manual lathe it works just fine to plunge straight in with a carbide insert. 29deg compound angle is what they teach in school but most folks in the trade go in @ 90.deg works fine and much less math.
Bonne video mais la vitesse de coupe me parait bien basse ce qui n'est geurre favorable a 1 bon etat de surface bonne continuation

It seems like you don't like to disengage the leadscrew. Like my self. Just afraid we losing so much time with forward reverse forward reverse.

It's probably a lathe meant for inch threading, meaning the chasing dial is useless when cutting metric threads.
bfeely 3 years ago
this machine has no start dial on it!

But you could reverse at Fast mode instead of slow.

bit slow
timmy3317 3 years ago
yes it's slow,remember it is a big 24mm thread in stainles steel and I have not fucked it up meaning it has not had to be done twice
