Man! That Fix8 is a turbo chip producer. The finished spindle is a real beauty. It's always very satisfying to watch you produce these artworks. Thanks, Chris.
Yeah, the chips are flying like bullets. I'm scared to get closer with the camera, cause if they hit you it's going to leave a mark. Take care Mr.Boschek.
Ual, i see , your job is so good, i was work in cnc lathe for 14 years, but i filled bad, lot of numbers in my head, now i work on manual lathe, but i appreciate your job.

Beautiful, as always, Chris. When the swarf conveyor is running in high gear, you're moving chips. That was a nice bit of threading. Thanks for sharing!

awesome video chris.glad i stumbled on to. it. i know what that spindle is used for i,m retired thread rolling machine oper and set-up man. thread rolling machine die or roll spindle. yeah love that chip breaking action.. i thought those were made via all grinding. thx for sharing
Great job! Bro, now i student of precision mechanics, here in Costa Rica, i want to make in the near future a job with such a fine finish, i only a 4 months old student, but someday i wanna do something like that, awesome job!!
Wow Chris that Kennametal tool is really impressive with how much it will cope with in removing material? Are they expensive do you know? Also I keep meaning to ask you, does your company have a proper store’s where you have to go get mic’s verniers and tool tips from where you have to sign for what you take out and put back in?? Thanks for all your videos I really enjoy them! I miss being in the shop and turning stuff out and would love to have a lathe at home if I had the space 🙃🙃🙃 From a friend of engineering in 🇬🇧 Andy 😊😊
The tool holder is like $160 and the inserts go for about $40 +/- depends who you get it from and how many. We don't have to sign anything for any tools. We are just a cnc repair shop, nothing fancy.
That's some beautiful work. Were you able to achieve the 16 rms finish when you slowed the feed down? Any time I needed the 16 rms finish or better, I put it on a grinder attachment.
It’s nice to see some REAL feed rates, my work has us running our lathes at a maximum of .010 per rev, averaging about .005 on soft materials like copper and it’s sad. I used to machine 4140 roughed out at .040 per rev
@@ChrisMaj I do semiconductor work so pretty much locked in with how we do things, how the program is written, hard to make any changes. Also don’t have any other customers. There are these little lathe parts about 1 inch long out of copper I make 2000 at a time sometimes, we use a bar puller so it makes 25 pieces per hour, they absolutely refuse to buy a sub spindle lathe ( a cheap one would work) with parts catcher and bar feeder. Could easily make it automated. But they would rather me sit there for an hour doing nothing, it takes 10 seconds to load another bar in. It’s crazy, they don’t care about production and we charge out the ass. That type of mentality makes everything expensive in America
@@ChrisMaj back in the day I would run my lathe at the highest feed rate possible and chips would fly because time is money. Any semiconductor shop is the exact opposite cultures for some reason
@@ChrisMaj we have about 20 different parts total between mill and lathe but for the most part most commonly run the same 4-5 parts everyday. I make 26.50 so not great but it has great benefits and we get bonuses constantly and they buy the whole Company good food every other week
Do you like those FIX8 inserts? Those blue chips sure look viscous! The seem like they can handle some pretty aggressive cutting. You're pretty good with those thread wires. Been using them awhile? LOL!
I'm starting to like that tool but it might be better for fully enclosed machines cause them chips can do some serious damage if they hit you in the face. Wires is what I only use
That tool is a beast when we do 4140 driveshafts at my work we run CNMG544 .300DOC .020Feed 400SFM. What is the name of the part you added to the spindle of the mics when measuring over wires?
It's an Anvil Attachment kit. I think there's 5 pieces. I got it years ago but it looks something like this. 7 PC Micrometer Tip Anvil Attachment Set Precision Ground a.co/d/fRnrOvY
@@ChrisMaj excellent thank you. Most of the time we just use 2 wires not all 3. The measurements are usually with in .0035 or less. We thread to fit to the mating part so being exact on the PD is not as critical.
It's a manual tool post so every time you take a tool out you have to measure again. I'll just take a test cut, measure it and punch it into tool offset.
A powerful lathe machine, but there are some workshops in the world that do not respect industrial security, and the water is mixed with oil. This is lax in the village, left.
Hi Chris, thanks for the amazing video. Like your stable and powerful lathe, that can handle the Fix8 tool. When adding water for the coolant, do you check the concentration ?.
That lathe could use a little more power, but it is what it is. I do check it once in a while, but most of the time I just kind of add water, add some coolant, add more water.

@@ChrisMaj Thanks Chris. I'm only doing smaller stuff up to 11TPI Withworth and 8TPI NPT. I'd consider that as peanuts compared to your threads :) BTW: Can the Fanuc control also operate in something like a manual mode, e. g. running single cycles without writing a program? Not sure if our ~2005 0iTC can do this. I prefer Siemens Manual Turn (from approx. 2000, now the interface is called Shop Turn) for one offs as you can do many semi-automatic tasks. Mazatrol is also a control I like and daily work with. I never really started to like the Fanuc control we have - like when you hit reset in the middle of the program and then hit cycle start it just continues where it was and doesn't jump back to the beginning. The first time I was like "WTF?". But that might also be a parameter thingy.
@@1AB09CC3 most of my programming is done with fanuc manual guide. I don't know about your control, but you have to hit that reset twice in order to go to the beginning of the program
Most of the time I take two finishing cuts. I'll check the diameter, make some adjustments if I need to and then final cut. With large parts like that I can just run one finish cut and hope for the best.

At 4.40 min you show the check on running true so I imagine that your 4 jaw can easily overpower the dead centre in the end of the part and push the job off the centre.
