I got a routine practice to hit the emergency stop button so when i see something fishy my hand is already on the way to slam the e-stop. This is a nice safety protocol. Be really familiar with the e-stop and do not hesitate to use it. Worst case scenario from using it is a broken insert or a drill. and worst case from not using it is a lost life. If the end of that bar would hit the top of the jaws then it could bounce straight into your face. There was a video of a guy getting hit from a piece of stock that hit the jaws. He had the door open and was standing close to the machine. The stock instantly knocked him unconscious and he almost fell into the machine but luckily he had a co-worker nearby who grabed him.
@@ipadize I struggle to find the video again but it is on youtube. Here is one that is somewhat close th-cam.com/video/EpWjecPS7hU/w-d-xo.html There is plenty of videos of machining accidents. Just search a tad and you find plenty.
Hey Daniel. I was very worried when you mentioned an up and coming crash. When it came to the arse pucker part of the video. I was dreading the worse. But actually it was not to bad. Thankfully. Looks like your starting to master your latest machine. It is on my Wish List, lol. Of machines to buy in future. Looking at buying something new. But Not for a few years still. My preference is a Doosan with a 10 inch chuck only C axis on the turret and like yourself must have a Sub Spindle. As you already know they come in very handy. Good to see the video,s from you. Big Thumbs Up, for future video,s. Peter.
Yea it could have been a lot worse. I have had worse just not on camera lol. I have had this machine tool change with the sub spindle in the way and snapped the parting tool off shattered the safety glass and the machine didn't even notice. I assure you tho it was very scary and was loud when that half inch bar just snapped and went banging around in the machine. Altho the 2nd turret seemed like a good idea its been more of a hassle to keep out of the way most of the time. Sub spindle is a must. At this point I need to get a good collet system for the machine as dealing with the chucks isn't very fun to setup when changing stock size. The machine is a total beast at taking off material. Its nice to get comments keep them coming man and I will try to keep these videos coming.
@@dnjmachine Yes shearing off material in a CNC anything can certainly wake you up, lol. I did a repair on a major CNC Lathe crash at one place i was working. The guy ran the Tool Turret that hard into the Lathe Chuck, it actually ripped the chuck off it,s mount ???? That was a very time consuming repair job and expensive too. Counting my time, replacement parts and the down time of the machine as well ???. Twin Turret machines definitely have there place. But for general turning work they are way more than you might need. A good collet system is a great investment, especially if you do a lot of smaller diameter parts. I need to keep the chuck on my machine as my work varies in sizes, from very small to fairly large diameter pieces. I plan to keep in touch with you as you post more video,s. You are right it,s good to get comments on video,s. It sought helps to make it more worthwhile posting.
That's pretty crazy I probably would have crapped myself had my spindle ripped off and went banging around in my machine. We do mostly collet size work but just hadn't gotten the time or money to buy anything for it. There is always something to buy... We have been really fortunate we have been able to get what we have I feel. The Mori did have a collet adapter not the Okuma tho. Thanks I should do the same for others but I'm barley keeping up with myself these days. Very soon hope to have some things smoothed out.
people dont realize spindles and sub spindlies are C axis and can position, lathes with sub spindles and live tooling are really cutting into machining center sales, it is so competive to produce a part complete with no second ops
Sorry on the delay, I just noticed a bunch of comments not responded to. I will post some code this weekend, I'm away from my shop and my code until then.
Ok, so this is kind of a broad question, You move the sub spindle like any other axis G00 posion. Example. G00 W3.125 move my sub spindle. If you have more than 1 turret its important to call out the turret G13 for A turret G14 for B turret Also important codes to know G140 for main spindle G141 for sub spindle M151 Sync sub spindle Here is the specific code I used to bar pull this doesn't include a spindle sync. WARNING!!! don't just run any code you get on your machine without understanding it, even when you do turn rapids down and single block on. This code is for reference only. I'm no expert on this lathe and I have noticed the same g-code responds differently on different versions of the Okuma. I did my best to comment it but there could be errors in comments.

Well shit happends, one time i didnt change the tool number in the program and the centerdrill mad a little crash coming on x axis, i shat my pants :))
Our machine is rather old and has no conversational. I been working though a post processor and have it mostly setup so use fusion for the bulk of the code. Sometimes modifications are needed. Live tooling we have not invested in them yet as they are pricey.
Its amazing how small that E-stop becomes in a time of need!
That's the truth!
Okumas do not stop for anything lol, some of the best machine tools IMO

Good points, I almost never work alone things always go wrong when your not expecting it and happen quickly.
soo where is the video? i need it for school purpose!

What did you say, son of a _________. Thanks for posting
That was actually my brother the whoa whoa whoa was me freaking out.
Haha the end was so funny, Wow woooowww
Thanks for sharing your mistakes 👍
i was suprised when i saw the pole just like sheared off istead of pushing or turning the tool turret, this must be a real robust machine
Yea this machine is seriously no joke. It leaks oil like a sieve into the coolant but its a beast
people dont realize spindles and sub spindlies are C axis and can position, lathes with sub spindles and live tooling are really cutting into machining center sales, it is so competive to produce a part complete with no second ops
How much lenght, can you get in subspindle, and diameter? I want to buy Doosan PUMA 2100LYSii, but dont find this information.
how to control rapid without single block option please
Mine has a rapid percent knob, So I just turn that down to 0 when I want to stop rapids without stopping the machine.
hi
D & J Machine! can you show me codes for suspindle? i cannot control it,thanks first.
Sorry on the delay, I just noticed a bunch of comments not responded to.
I will post some code this weekend, I'm away from my shop and my code until then.

Ok, so this is kind of a broad question, You move the sub spindle like any other axis G00 posion.
Example.
G00 W3.125 move my sub spindle.
If you have more than 1 turret its important to call out the turret

Also important codes to know

M151 Sync sub spindle

Crash?...
Well shit happends, one time i didnt change the tool number in the program and the centerdrill mad a little crash coming on x axis, i shat my pants :))
you actually use g codes for okuma?
don't you have conversational programming? what about live tooling
Our machine is rather old and has no conversational. I been working though a post processor and have it mostly setup so use fusion for the bulk of the code. Sometimes modifications are needed. Live tooling we have not invested in them yet as they are pricey.
