15 G0602 Turning Metric Threads



I learned how to thread by watching Tubalcain's Youtube channel (/user/mrpete222/videos?query=threading), and with some help from John Grimsmo (/user/JohnGrimsmo). Even though I had plenty of help, it still took me FOREVER to get a single usable thread.... Then I got another :)

This may not be advisable on your own personal lathe but at school when
dimensions don't permit a minor diameter "relief" or "runoff" cut ill
thread as close to the shoulder as I'm comfortable hit the foot brake and
simultaneously back out the cross slide. Hitting the brake probably
stresses the lathe in one way or another but you sure do get nice threads
haha. I've found that .003 cuts are good for roughing, an when your down to
the last .005-.010, .001 or less gives a great finish. Cool video and yes
mild steel sucks

Автор Michael Nooij (6 месяцев)
29.5 degrees is not enough for cutting on 1 side, 27 degrees gives best
result.

Автор seditiousmonkeyart (10 месяцев)
The biggest issue you are having with your thread cutting is the lathe
itself, and has nothing to do with it being a metric thread, mild steel or
hand rolling the chuck. These small lathes simply lack the rigidity needed
for thread cutting, especially the smaller threads. The flexing is a big
factor to poor thread quality and tool breakage. This applies to parting
also. This is also an issue for carbide or insert tools. You simply cant
cut at the correct cutting speed on the small lathe. I agree with the
others, use HHS and you will get a better finish.
Others have also pointed out the depth of cut you were taking was way to
much for the mini-lathe, ergo point 1. You have addressed this in part by
reducing your cut and by positioning your compound to 29.5 degrees.
Might I also suggest that for such small threads use a die rather than
cutting it, much faster.
I hope you are having more success these days with your thread cutting.

Автор Stantonleman (6 месяцев)
Good to see you got carbide to work. I know that was not easy. Carbide is
brittle, provides a rough surface finish at low speed, and requires higher
tip loads. Those reasons are why I switched to HSS tooling (i.e. I gave up
on carbide). I found using HSS for thread cutting with lard oil (available
at McMaster-Carr, MSC, etc.) helps considerably with mild (1018) steel. I
use a hand crank to drive the spindle when threading. Some HSS tooling I
ground but A.R.Warner sells HSS insert tooling (also sold through little
machine shop).

First to thank you for all this videos I got same machines as you do (g0602
and g0704) and your videos help a lot.
So I have been researching inserts and as you may already know every
manufacturer marks them in their own way so its hard to know what kind of
material they are meant to cut. Diferent iserts are made with different
properties. Some are meant for harder and some for softer metals. From
China there is C2-C6 mark that is used to define hardness of insert carbide
but with name brand ones its hard to figure out but visually. At end maybe
grade of tool may not be best for softer steel.

very rare that someone will reveal the truth. I respect you for that.

Автор slapfrog (8 месяцев)
Try using threading oil, I thread rigid metal conduit at work and there is
a night and day difference between the quality of the threads when you use
motor oil compared to threading oil. You can pick up threading oil at Home
Depot or Lowes in the plumbing section. Apply a light coat each pass and
you can thread mild steel very nice. Hope this helps.

Автор Charlie Moore (1 год)
Hi russtuff, I would get the same results with mild steel too. I like to
use drill rod for any home made shafts it threads really good. As suggested
try using a HHS tool that you grind your self. also get your self a pitch
gauge. it has the double depth measurments for the threads. although not
for metric threads.

Автор russtuff (2 года)
@UCMWINGS I have no way to grind blanks and the pregound ones cost more
than what I think they are worth. Granted, had I started with them instead
of carbide I am sure I would feel differently :)

Автор jchinderle (1 год)
hey there, i think one of your probs may be taking to big of a depth of
cut. when i learned how to turn threads in tech school we were taught to
start with a doc of .003-.005 but as you start getting into the material
you have to bring the doc down to .001... it takes longer but it wont chip
your insert or sharpened hss and you have to think, when your cutting
threads the chip load isnt just on the tip but also on the sides of the
tool so youre taking a depth and width of cut.

Автор russtuff (2 года)
@patrickdarcy Right! I am a bit surprised I haven't been told "never do
that" yet. I'm sure I'll get it eventually :)

Автор russtuff (2 года)
@DallasFFL Congrats! Have you played with the dials on the front at all? It
sounds like it may be in between settings, which will disable the leadscrew.

Автор Andrea Evangelista (2 года)
I ran out of space again. If you are in the Los Angeles area I would invite
you to my shop and in a couple of hours I could have you threading like a
champ. Alternatively, we could Skype, thereby allowing you to see in real
time responses to questions you might have and see in practice what I could
show you. I would like to see you do a better video with good information
and nice results. Good luck either way, machining takes time and is hard to
learn on your own. I know the problems.

Автор makun16 (1 год)
The reason for turning the compound in at 29.5 degrees is so that you on
cut one side of the thread and not both. By doing this, it will give you a
cleaner thread and prevent the root from being torn out.

Автор russtuff (2 года)
The feelers may have not been ideal, but they did get it done. Using a
decent steel really was the difference in breaking tools vs getting a good
result. Thanks for watching!

Автор Brad Trelstad (2 года)
Hey thanks for the instruction. I just picked up a lathe like this and it
doesn't have a Thread Dial. I also have to try to figure out how to center
the tail piece. I'm looking forward to how you did that. I'll be taking
apart the tail pc. tomorrow to do the cleaning like you showed. Mine is all
gummed up as well. Thanks again, ChiefBDT@gmail.com

I've had no problem doing SAE threads with this lathe and using the timing

I picked up a 1x30 belt sander from HF and it does a great job on the HSS
bits. Wish I had gotten one with disk as well. I also picked up a diamond
grinding wheel (#32397) that I just chuck up in the lathe and sharpen the
brazed carbide bits since they have not been that sharp when I get them.
People say HSS is sharper than carbide but after some quality time with
diamond stones on the carbide, I can't really see that much difference.
Probably just because HSS is easier to sharpen.

Автор russtuff (1 год)
I really do need to get working with HSS. That said, once I started turning
12L14 I had great luck, so I have been trying to work with it whenever I
can. Thanks for watching!

Автор russtuff (2 года)
it didn't make any sense to me either at the time, i was just doing what i
was told. basically, the leadscrew is an INCH pitch, so you can't turn
METRIC threads by disengaging the half-nut and reengaging at another point.
when turning INCH threads that is exactly how you would do it, but for
METRIC you must leave the half-nut always engaged. it's dumb.

Автор Perius (2 года)
If I remember correctly, the main reason for setting cuts at an angle is to
reduce the stress on the tool. Less surface area in contact with the
material gives less chatter and less strain on the workpiece. Some
machining tips: Make a metal hook to pull out the shavings. Don't use your
hands! Nor pliers, they might "hook on" to the shavings spin around and hit
your face. Buy some proper cutting fluid. Use alcohol as cutting fluid on
aluminium. Use dishwashing soap and water on plastics. Have fun

Автор bubster1981 (1 год)
Yea!, , but metric threads are spot on.??? I thought it having an imperial
lead screw 12 t.p.i it would be better suited for .s.a.e threads , guess
not. Yea , scratch out a 13 tpi thread and closely measure it ...or any for
that matter an see what you get...or measure the carriage travel per
spindle turn (accurate 1 turn and backlash removed frm carriage) and see
what you get. 13 tpi equals 13 spindle turns divide 1 inch carriage travel
.077''/ rev

I made a swing up tool holder for threading a while back. Instead of
backing off, it swings up out of the way. Copy idea from Bogstandard on
madmodder. He has a video of his in action here under the user blogwitch.
HSS is sharper and better for light cuts. Carbide seems to want a bigger
depth of cut to be happy. Metric leadscrew makes metric threads a no
brainer though...

Автор russtuff (1 год)
WHOA! I am going to have to try that and see what I get. I haven't any
problems like that, but I also have only cut a few threads.

so stating it isn't as helpful as offering tips on how to get better

Try grinding your own HSS tool, you can grind HSS to a much sharper edge
than carbide, the tool still doesn't look like it's cutting cleanly there
doesn't seem to be nice coils of swarf coming from the tip, you could also
try grinding a little bit more of a positive angle on the top of your tool.
Thanks for the video, I enjoyed watching it. Regards Tim

Автор 65ply340 (1 год)
Sharpen your own tool bits out of 3/8 high speed with a 60 thread gage for
a pattern, put on center line. Use some kind of cooking oil for lubricant
(any seems to work) and you can cut cold roll, stainless, brass, aluminum
etc. Throw away that carbide not sharp enough, but will work with hardened
steel. You are right - leaded steel cuts the best.

Автор bigdicdangler (1 год)
hey Russtuff, you got a machine capable of making new gear bushings, why
not make a few so you don't have to press them out?

Автор russtuff (1 год)
Uh... why didn't I think of this? Great idea!

Автор bubster1981 (1 год)
its interesting , because if you take 20 t.pi for instance ,the carriage
should move .050'' per spindle turn...if you have an error of .0025 per
turn, doesn't sound like much , but over 20 turns that's an error of .050''
which is a thread plus or minus! gives you an idea how precise thread
cutting really is

Автор bubster1981 (1 год)
My fault,my fault! sorry for the mistake, but this lathe is a decent thread

Wow I forgot all about those gears haha. I vaguely remember being able to
do it without a press, since I don't have one. RE 12L14, I found that it
turned weird, like cast iron with short showers of chips, not long stringy
blue chips like other steels, also the workpiece and the pile of chips
rusted within days, so I'm not a huge fan. Love turning 4140 though! Great
vid bud, doing it under power certainly helped. A little bit of thread
wobble is perfectly acceptable.
