CNC Attachment for Manual Lathe

[@DonQuichotteLiberia]

The editing, script, machining, engineering, design -- everything is top notch. I feel honored to have witnessed the masterful performance of a modern-day Leonardo da Vinci in these dire times.

[@kerkkonenahaima7322]

I'm glad you liked and thanks for kind words! I'm flattered and da Vinci would probably be offended.

[@bobuilt10]

What a fantastic idea. You have created the best of both worlds. The flexibility of a manual lathe and thr repeatability of a cnc. I have the Triumph 2000 and it's quite rare to see the larger Colchesters on KZbin. Very well done.

[@andrzej3511]

Kerkko, I simply have no right words to appreciation for your achievement. You have turn an age-old lathe into a very modern machine with possibilities limited only by your imagination. The second thing that should be emphasized is that for simple turning works the CNC attachment can be easily disassembled. An elegant and effective solution. I am extremely impressed.

[@T0tenkampf]

This is a very well thought out design which requires much less modification to the manual machine than I had envisioned possible. Now I only need to dream of finding my own Colchester

I have two things I regret in that scene. One is that was made in the first place. The odour lingered couple of days in the workshop and had some guests wondering the origin. Second thing is the bottle should have being rotating and the cap should been formed out, It´s a lathe after all. Next time wiser. Thanks for your kind comment!

[@kerkkonenahaima7322]

Thank you Paul! I have certain allergy against Chinese machines, though I own some. Preferring western equipment has turned my workshop somewhat as a museum of technology. Many Colchester lathes have nice clutch system that engages the spindle, the motor runs all of the time. That gives silky-smooth starts and reversing for the spindle, this is very useful when single point threading without an indicator dial.

[@paulbrodie]

[@kerkkonenahaima7322]

This would definitively beat any mini-lathe on that. I would choose bigger motor for compound slide, the trapezoidal (Acme) lead screw has terribly bad efficiency under heavy loads. Material removal on large diameter steel parts can easily make the motor lose some steps and expensive stock is ruined.

[@Mr3mars-tons]

Very nice my workmanship friend, and it’s nice to see old school blueprints as well, I began learning mechanical drafting in 8th year of primary school, and I fell in love with it on the first project assigned. Even though I’ve long since learned CAD, I still prefer to draft out my concepts by hand first & then go copy into CAD. I work off of paper plans any day rather than off a computer screen, (even though it will have to be done if g-codes are needed). However once I have everything down and finalized, I always print a fresh copy and give it another study before I start to make a project, I just like the paper, & it’s handy to have if I conceptualize something new while in the process of a build, I flip it sketch it! Also ya got another subscriber today, looking forward to more fantastic ideas and videos!!!…

[@kerkkonenahaima7322]

Thank you! I'ts quite funny, that when you make a drawing in the CAD, you can stare it all day on the display, but while the printed sheet is still warm you have already found couple of missing important dimensions on it. Next you go to milling machine or lathe and wonder why the origins of the dimensions are awkwardly oriented wrong way around for the operation.

[@kerkkonenahaima7322]

Yes, I will do a YT project video for that in near future. The current terrible sounding prototype functions just great, but is little too complex with the planetary gears.

[@c4t4l4n4]

It was interesting to see you use a parting tool to shape the egg cup. There is the cutting action of the leading edge, then a programmed travel to register the trailing edge into its cutting position. I suppose you have to choose carefully what parts to use this technique on. 👍🙂

[@kerkkonenahaima7322]

You are right, that is not the most optimal tool, but was the one I had in my hands for testing the gadget. Fusion 360 CAM handles just fine the paths for such tool. I bought later full radius carbide grooving inserts and turned some bead roller dies from toolsteel with great succes with this CNC attachment. Flat parting tool can sometimes be very handy on a hobby CNC-lathe without tool changer; small production runs can be carried out with single program without annoying tool changes.

The geometry of that quick change tool post is suboptimal at best. If you happen to be greedy with cut depth and holder gives even slightly, it will extend the tool further out and worsen the situation. I learned to like the fish tail type holder, although I would prefer the kind that I do not yet have.

[@kerkkonenahaima7322]

I haven´t had problems, that I could put the blame on this quick change system. The repeatability is not the best, it must be taken in account in production runs with tool changes. The dovetail may be better, I have never used such. But I have some bad experiences from cheap Multifix clones.

[@heinzhaupthaar5590]

@@kerkkonenahaima7322 At least with german diy cnc folks it's relatively well known I guess, probably due to Isel being german and very common with the diy crowd.

Would like follow-up video when you mail the threading problem , suspect you may need quadrature encoder on headstock spindle.

[@kerkkonenahaima7322]

Yes, that's on my to-doo list, but will require some research first. Mach3 can only take simple one pulse / rev signal for threading, but I was not able to get the indexing running at all. Real encoders are out of the question with Mach3 if I understand correctly. I think that my breakout board doesn't support threading at all. I will probably change the control to Acorn you suggested or Masso or whatever I think would do the job properly. The casing will not take anything bigger electronics inside and while it needs major changes I can change at the same time the Z-stepper to something with more torque. But right now it will have to wait for quieter times in the workshop...

[@airgunningyup]

i tried to get mach 3 to read the index pulses for months , never got it to work.. any luck ?

[@georgetirebiter6437]

To have a better experience in power-snapping m3 or 6-32 taps in cold rolled cheap steel, or other ductile materials, convert your tap drills and taps to thread forming or “roll taps”. You wind up with stronger threads and fewer snapped taps. Indeed, you have to do some stupid things to break a tap with a forming tap, like trying to tap D2 tool steel. Also, a colchester lathe has the torque and rigidity to convert to CNC, so good choice. Other good choices would be other gear driven lathes and Monarch (my favorite manual lathe), which is DC motor driven, and silent AF when turned on.

[@kerkkonenahaima7322]

I have some experience of forming taps with Flow-drill friction formed draw holes on stainless sheet metal, with rather good success. I haven't never tried them on more solid parts, but certainly will give them a try in the future, thanks for the tip. Monarch lathes are quite rare this side of the Atlantic, but what seen on KZbin, they seem great machines.

[@martinconnelly1473]

I put an index on my lathe spindle and tried to get threading to work but failed until I put a Warp9 Smooth Stepper breakout board into the system. You have to read the breakout board specification carefully to avoid this problem. As you have found, they do not all allow threading from a single pulse per revolution.

[@kerkkonenahaima7322]

Warp9 seems to be good option here. For the card I used, there was not much manual to read. I kinda assumed they all support this pretty basic function, now I know better.

Nicely done!!! I have a nice metal lathe but it terrifies me. I think I will go your route and make it CNC so I don’t have to go anywhere near that death trap while it is in operation. Worst that I would expect is a crash from a broken cutter or mistake in the gcode.

[@kerkkonenahaima7322]

When the code is CAM-generated, most hickups can be seen in the cutting simulation. I run my CNC-attachment so that the compound slide hits its physical travel limit just before the tool reaches the chuck jaws. So it's kinda safer in that manner than real CNC-lathes. But you are right, this amount of rotating mass doesn't stop in a blink of an eye, if something crashes.
