LATHE MACHINE THREADING

[dreamteam1901]

No one now`s. On CNC-Lathe i`ll take more RPM and Cool_Water on the Cutting-Steel....

[Tunerboii2045]

why are you using a 4 jaw chuck too hold a round bar? it just makes it harder too run concentric?

[CuriousEarthMan]

Great to see! Thanks for posting!

[lennul1]

i want HIRE :( i can thrade that in 10-15minutes by the speed of 700..please

[MrSheissen1]

@lennul1 I WANT FUCKEE!

I used to grind my own HSS threading tool, but now use a carbide insert cutter. They are indexable, make a smoother thread, and save time. But they have to be run faster, or they gouge, This can be tricky, especially if you're threading up close to the chuck. I almost always use a good live center, too.

[anglocowboy]

Try turning your tool upside down, reversing the spindle and feeding out toward the tailstock. Much easier. Also, watch those birdnesting chips. They're unsafe and mean you're not dispersing heat very well.

[dazzpazz]

@anglocowboy I will try it. thanks for the tips.

[lepompier132]

@anglocowboy That type of threading is best done on a CNC lathe, because on a manual lathe you have to remember the depth pass and add at each pass. But since you only have a manual lathe. Try to finish the machining first and end with the threading. That way you don’t have to plunged-in with you’re the threading tool and risk breaking the threading tool.

cutting oil would help

[kellyttr]

thx for the vid it will be useful in our next activity(already done with facing, turning, tapering and next will be boring and threading)

[ThePoseidon211]

chatter and blue chips be careful you gonna rip that mother fucker out

[daislynforever]

reverse?



[dazzpazz]

@daislynforever nope! it's just look reverse when threading but when you turn the nut it's will turn in the right direction.

[dazzpazz]

@daislynforever but there are instances that you have to reverse the threading so that the nut will turn in opposite direction.

[ThePoseidon211]

@dazzpazz yea left hand threads haha

[YseraFatbeard]

for my first project i got in my basic millwright class is making a 3/8 Nut and Bolt Left hand threaded out of 1inch Cold Roll, i got the threading done all nice and perdy like, with the nut threading on with ease but when i got the bolt on the milling machine so i could make the head into a hex i fucked up and made 2 sides uneven... had to restart...

[bjlibrero]

galeng ah. kahit papano sentro pa rin. malaki na yung 4-jaw na yan. kung 3-jaw or 5-c collets attachment sana. pero astig. :)

[Ahmet42Alp]

I use to thread with 50 RPM. This is due because I'm still in 1st class machining and we have to be very steady and precise and do it slowly or either we could risk by damaging the HSS Thread cutter which is easy to break.

trade test nmin yn sa don bosco

[Melismedmajs]

Thats so awsome, im starting at mechanic school next year. Do we use this there?

[dazzpazz]

@Melismedmajs i don't know the exact mechanic teaching approach in your country. maybe they will teach you how to thread in the later part of the course if it is included in your topic (lathe machine) because you need to know first the basics before you can do the threading works.

[hassansafdar92]

great work !!

[ravagash]

pare ilan feed mo bawat pasada ng threading? tnx!!

[dazzpazz]

@ravagash 3000 to 5000mm pre

[ravagash]

tnx pre. ano nga plang material yan ska anong type of steel ng tool bit na gmit mo?

[dazzpazz]

@ravagash shafting cast iron ung materials na ginamit pre. ung tool bit high speed steel o ung tinatawag natin d2 sa pinas na tungatip o momax.

[11mauren]

@dazzpazz eh ano nman size nman ng nut n ginamit m?

[dazzpazz]

@11mauren 1 inch yung size ng nut na ginamit dyan sa video. (the size of the nut that was used in this video was 1 inch.)

[bjlibrero]

@dazzpazz bakit ganun, parang hindi sabog yung biruta? pero mukhang malambot lang yung materyales. thanks.

[dazzpazz]

@bjlibrero depende yan sa speed at sa talim ng tool bit (high speed steel). minsan kelangan mo rin timplahin ung speed at ung talim ng tool bit. dapat kabisado mo ung machine at syempre kelangan ng practice pra mamaster ung threading.

[lincolnvelasquez]

is it metric or english?

[dazzpazz]

@lincolnvelasquez it is in english but you can set it in metric if it is needed.

[lincolnvelasquez]

i prefer to use 300 rpm. the surface finish is unbelievable.

[dazzpazz]

@lincolnvelasquez the lathe machine had no threading dial anymore. so i have to operate it in a moderate speed so that i can engage the tool bit at the right position.

[BigAgitator]

@dazzpazz It's impressive that you did it at all- wthout a threading dial! One cross thread and you'd ruin the whole piece. Very nice work

[TheALONE25]

what rpm did you use on that threading???? nice ha

[dazzpazz]

@TheALONE25 160 rpm

[cumulo25]

What brand and model is that lathe, anyway?

[dazzpazz]

it's NAMBA made from japan.

[cumulo25]

a lot of people (I know) hate threading, or think it's really difficult. I find it rather easy. you did a good job on those threads.
