40" SHEAVES, CNC VTL (Koło linowe, tokarka karuzelowa cnc)

CNC VTL GOODWAY GV-1600M

[@johnnybodank959]

Been running vtls w/out live tooling since 2006. Now I'm looking for a job on vtls with live tooling. Been hard finding someone willing to train me. Atleast watching your videos has given me an idea of what it's like.

[@bones357]

This vid had it all, and I appreciate all the effort that went into making it! Tool changes, setups, indicating, setting paramaters on the PMC, and the final results! 👊👍

[@wheelitzr2]

You made that OD tape look easy! Thank you for sharing.

[@gaminggami4138]

You make some great videos Chris, i love watching em. Btw i would love if you could post some videos regarding the programming and the set up procedure.

[@anrmanufacturingltd4436]

Great video, would love to see more of what you do.

[@MWL4466]

Nice job Chris. The company i work for uses these sheaves of all sizes. We are its lifting division. The equipment these are installed in get a lot of abuse over the years. Greetings from Canada.

[@userwl2850]

At 3.00 in my last video I mentioned you using that tool Chris. That is a beauty of a job you're doing here. 👍

[@patrickdean9797]

i like your trepanning videos David

Gracias Chris......saludos desde Medellín colombia,.....un abrazo

Excellent vlog, I was puzzled by the AISI 1060 material, then you showed the final machining on the VTL. Good to see a small part of the programming, I assume this Fanucs "Conversational interface"?, I am only a newbie on Proto Trak (South Western Industries). ATB from the UK. Regards John.

hello very good your work. I never worked with a vertical cnc lathe.

Chris, you will need a nice piece of cod to go with all those chips... know going to watch the rest of the vid. ATB from the UK

[@jimsvideos7201]

These parts seem a lot nicer than they need to be, but that speaks well of your work and leads me to wonder why the engineer would draw it that way.

[@whatevernamegoeshere3644]

Well. If there's an edge or burr, it fucks up your cable that runs on it, if the cable is screwed, the next roller is screwed too, if it's excentric, your axle will be screwed... You can either make it nice or make the whole machine short lived. One thing is sure tho, if you do the latter, you can't really expect them back ever.

[@jimsvideos7201]

@@whatevernamegoeshere3644 That makes sense for the rim, it's the rest of it which seems over-done though.

[@cambrowndrums]

@@jimsvideos7201 that’s engineers for ya, the whole point of a machinists job is to make the part to the drawing specs no questions asked.

[@jimsvideos7201]

@@cambrowndrums If the engineer can convince the bean counters to pay for it, they can have whatever they want; that doesn't bother me in the slightest.

[@ipadize]

seeing big chips popping off is really satisfying. Today i cut 1.2083 with a Fraisa endmill (37mm doc, 1mm woc, 0.1mm/tooth). Not as big as those chips but still

How do you deal with coolant foaming while washing splinters?

[@user-dm8vh8yy4y]

[@mattcaesar5781]

Great job you know what your doing. When your finding center is there a reason you dont touch the side of the tool and add or subtract 1/2 the width? Also whats your feed and depth of cut for that vnmg. Thanks

[@ChrisMaj]

You just set your live spindle offset in the center of your table. If I remember correctly DOC: 0.070" FEED: 0.018 IPR . I probably could have used that tool with round insert but that VNMG was breaking the chips nicely.

[@MarkAllan1]

This is a great channel really interesting. Chris Ive noticed the revolution speed increases the closer to the centre of the part, why does it do that and not the other way round ?

[@colehoulden9127]

The smaller a part the faster it needs to spin. Rpm calculation is (12xCS)/(Pixdiameter of work piece). I.E. CS for 1018 crs is 70. (12×70)/(Pix1)= 267 rpm. A 4 inch part would a quarter of the speed.

[@tristinknee5650]

Is there any way you could share your program creation process for this machine?

[@kisspeteristvan]

mmm that 3" spade drillbit requiers a lot of torque .Even the milling spindle is impressive on that vtl . Coolant looks really bad , hope it doesn't smell .

[@ChrisMaj]

I don't know what's with that coolant but it looks like this after about a week of use, but at least it doesn't smell. I don't know if it's the coolant or the high pressure pump and there is 250 gallons in that tank.

[@kisspeteristvan]

@@ChrisMaj Interesting... , on the horizontal that i work on shit starts to grow(fungus or something) after a while , has to be found and cleaned periodically , but cooland color is not affected by that .

[@DailyGyu]

Excellent. How did you do c-axis machining? I am very curious. I want to try it.

[@tristinknee5650]

I'm not Chris, but I program a similar machine. There is a milling mode and a turning mode on my machine. When milling mode (M35) is active, I can control the orientation of the spindle in degrees, or I can program like it's a standard mill even though there is no Y-Axis. What Chris is doing in this video is most likely Polar Coordinates control since it works wonders for drilling, tapping, and other non-interpolating movements. All you have to do is specify degrees. The other milling mode is Polar Coordinate Interpolation (G12.1), and this allows me to use the X and C, instead of X and Y, to mill a square pocket for example. The machine manipulates the X and C axes together to act as a virtual X and Y axis.

[@tuantq06]

What machine is that?! Used to work with an OM VTL. Looked just like this. But the coolant eye is a bit different

Don't agree with your choice of tooling. Rough facer was chattering, 80° straight vertical needs pocket support. Question. What's the true repeatability of the tool changer? We had a similar machine style and just fought the. +--.0005" bore.

[@ChrisMaj]

DOC 0.150" and 0.030 IPR I think that tool did pretty good and there was no chatter. I haven't had any problems with the tool changer so far.

[@jimsperlakis5634]

@@ChrisMaj I had to replay to make sure I was reading it correctly. That was impressive. It only squealed on the 1st few inches of facing. I'd have used the 100° edge if all you were doing was facing.

[@jimsperlakis5634]

What is the true repeatability for a tool from part to part in the real world ? We fought the tolerance constantly. I've been retired from cnc programming/processing for 17 years but I still love watching how people are doing it. I had everything from old Excello NC machines & Burgmasters to new twin spindle Motch 235d, Hessapp, Warner/Swasey retrofits, Fellows cnc shaper and Sip cnc jig bore plus many used from cat Peoria.
