PM1127 Lathe turning steel into chess piece.

PM1127 CNC lathe conversion turning steel into chess piece.
Please excuse the photography. I borrowed the camera and it was giving me trouble.

[@RichardNash100]

I love it I could watch this machine do bits all day

[@therenboster3024]

excellent demonstration of roughing and finishing cuts!

[@daalhoffarm]

Wow i wasnt expecting this to be a small Chinese lathe! Your work piece is sticking out very long to do those agressive cuts, thats what i was thinking. This mini lathe was pushed to the max...

[@oldman6495]

I just picked up an old Lodge and Shipley copymatic lathe. Making a chess set was my first thought. Maybe Brass and Aluminum. All I need is to set up the hydraulic pump to run the copymatic system. Very cool!!

[@GeneralChangFromDanang]

1:56 Looks like your lathe was hittin' the bottle earlier lol.

[@ydna]

nice chips...that's some aggressive cutting for a 35 insert, it did the job...

[@JRo250]

Cool machine. I agree with some of the comments that you were taking rather big chunks out of that piece for a machine this size... and with no coolant/lube. Hopefully by now you've gotten yourself a better CAM software package that doesn't cut air. Most modern CAM take this into account.

[@depenthene]

Pattern repeating cycle. Some controls can't cut pattern like that with turning cycles so easiest option is to make pattern repeating cycle.

[@justtim9767]

Brutal DOC.

[@ellamuller3336]

Soooo satisfying

[@wolfitirol8347]

You use the same lathe as we know in Germany / Austria as D290V from China I have it a year now and am very satisfied...

[@jonassporsheim3779]

Wow, such skills

[@The_Joker_]

This is painful! HELP I need A drop of oil

[@mikhaelabarrientes5347]

what metal is used in this video (the one his working with) coz we're also gonna do something like that and we've got no idea what metal to use

[@edgarascorpion3117]

Se nota que ese programa lo hizo algun estudiante o aprendiz ya que aun tiene muchas fallas durante el proceso de desbastado ya que hace muchos movimientos inecesarios, asi como la herramienta no es la adecuada ni para el acabado, pero todos empezamos asi, buen video

[@ARIFINLATHE]

Nice ...good..💯

[@skeeterweazel]

Pretty fancy turning there. Is the lathe motor stock?

[@TheMindOfTheAll]

turning BDMS without coolant :O mad guy!

[@joeyvpoisonfree]

That bishop is on fl33k

[@dirkspeed3120]

The Cutter is a carbide insert.

[@amanandhischainsaw]

This is impressive considering it looks like its being done by hand

[@qualeb8164]

Hella Jeff lol cnc

[@MrThenry1988]

Lol. Mine don't go like that.

[@htowler5293]

Is this automated ?

[@ElaBellll]

is it possible to do a curvey shape like this if its not cnc, it seems like getting the head to move like that would take extraordinary skill and cordination.

[@NathanPaulViney]

Technically possible but I wouldn't try! Ideally get yourself some different shaped cutters or make your own :)

[@therenboster3024]

+OLEMINER49ER It certainly is but the cost of tooling! that and its laborious.

[@norbertvarsanyi2580]

+OLEMINER49ER it is simpler than you would think! He more than likely uses a shape of an already done chess figure. The lathe's set in a way that the tool will move like the finished chess figure. That's why he moves the tool according to the shape of the figure even when he is not cutting the steel with it.

[@sodalines]

can you turn a peace like that without it being cnc?

[@sudo_nym]

''piece''

[@TarponDaddy1]

I know it's ben a few years you did this video but would you have the GCode for it

[@lacaver64]

its an cnc？

[@ksb2112]

Were you playing the soundtrack to Eraserhead at the end there?

[@Guitcad1]

I'm no machinist so I have to ask, how is that blade not red hot and melting? That _has_ to be generating an _insane_ amount of heat!

[@MF175mp]

It's tungsten carbide, the steel will vaporize before that melts and it's hard as woodpecker lips

[@danc1197]

1 down, 31 to go. You would also want a steel board.

[@indianajones6407]

Hot rolled steel.

[@sagatbalrog]

is it doin it by itself

[@CoolGuyCoolFly]

sagatbalrog Yep, it's done by CNC.

[@middlemanclayton1]

good old g73 pattern repeat :D, or is it g74? been a while since ive had to can cycle. nice bit of turning btw

[@Zkkr429]

Would have been better using a G71 roughing cycle.

[@middlemanclayton1]

Josh Hanson depends, some older controls like fanuc for example cant handle complicated shapes, you cannot program a shape that goes from big diameters to small doameters, some machines will only turn small to big, if you try it you might get an error code "shape not monotonously" and your right, g71 is much better to use because pattern repeat cycles cut a lot of air, nowadays i use mazatrol which is a piece of cake

[@Zkkr429]

G71 has two types of cycle, you differentiate between the two in the first line of your block after the calling the G71 cycle. You need to put in both an X and Z value and it will do a non monotonic shape. Even old Fanuc controls can do this.

[@middlemanclayton1]

Josh Hanson really? have tried this on our older machines, fanuc Oi an O series do not seem to support this as errors occur even when you define x and z values on the first line

[@Zkkr429]

I use Fanuc 10 controls, there's type 2 G71 on those and there definitely is on 0i TD controls. I am not an expert on all different Fanuc controls and I have looked up that some don't support this cycle. They must be REALLY old controls that I haven't had the pleasure of using.

[@virustwin]

what is the chisel tip made of?

[@NathanPaulViney]

tungsten carbide by the looks of it

[@CoolGuyCoolFly]

Nathan Viney Definitely tungsten carbide.

[@Pendragon501]

What's the cutting bit made of?

[@ryanhankin8304]

1984sFinest carbide

[@charliemooney5742]

1984sFinest

[@MAAZ_Music]

1984sFinest Silicon carbide (SiC)

[@hardcase1659]

No it's not. It's Tungsten Carbide

[@1metiz]

Quite a bit of chatter with those feed rates

[@EllenDegenerate3588]

+1metiz it looks like its getting too hot as well, you can see how the brass cutting tool is bluing the steel that its cutting off

[@getfookedweeb7484]

thats normal

[@EllenDegenerate3588]

fair, I have no experience just observation

[@getfookedweeb7484]

this was automatic right?

[@ethanjones3482]

no, by hand

[@qualeb8164]

Arno Van Nieuwenhuyzen it says cnc in the desc so i would assume it was automatic unless this guy has super fast hands

[@tom_kearley]

and that's how you get circumcised

[@kasanahsagi3236]

Can yo give me a job sheet ???

[@MrThenry1988]

That ones not like mine. Lol.

[@eswarsaitej7074]

No coolent goddddddd

[@t3chfr3ak]

Why would you profile cut your rough cycle? A waste of time cutting air.

[@oxm18]

Why dont you made an air rifle?

[@calibra8125]

Wirtschaftliches arbeiten kann man das nicht nennen.

[@Neodymio]

Está mecanizado para el culo.

Your feeds scare me, your DOC scares me, finish is eh.... try again
