For years I have run jobs like this on my Manual Lathe. But, thankfully times have changed and I can finally justify the need for a CNC Lathe to run jobs like.
Hello Peter, Sorry I have been on the missing list, back now... Nice to see your subscriber count is rising nicely. Interesting video. Take care. Paul,,
It's good to see you're still around on RU-vid I tried searching for your channel a few times, but every other channel besides yours was coming up ?? I must admit I did unsubscribe some time ago when you stopped posting. It's nothing personal, just me with my not using throw it out mentality 😒 Looking forward to inviting myself back and seeing what you're up to at the moment. Thanks for watching, and I'm looking forward to seeing more from you 👍
I'd run the process: Drill first, then use your O.D. turning tool to turn away from the chuck, chamfer, face, then part off. Three tools instead of four.
I guess it's worth trying a different way to make these parts. It's mostly the Parting Off op that gives me most drama. But thanks for sharing your thoughts, Peter 👍
@@weldmachine It has been a while, but I saw a video where the person used a piece of wire attached to the tool changer that would catch the part after being parted off. As for the bird's nest, I'd try plunging faster. Thicker chip, but less of it.
@number40Fan I actually use a wire to catch the small nylon washers I showed in this video when I am Parting Off. In the same way as you mentioned, lol 👍 I could increase the feed rate on the Parting Off op. But, not many of the parts would land in the Parts Catcher ?? IF I was running a lot more parts, I could possibly change a few things to make this job run unattended. But, it's only 300 parts, which is still a fair few. But, IF it was a job that took a few days to run, I would definitely try to improve things a little more. But, I'm sure by fixing 1 problem, I will create a new one. Always like that 😒
Have you tried to run a "chip breaking" cycle with your drill? Not specifically a peck drilling cycle where the tool rapids to the end of the part, just backing off a millimeter or two to break up the chip. Also, Im not sure what you are using for programming but I think there is a setting or a way to program your part off where you slow both the feed and the spindle speed way down so that when the part breaks away, it is less likely to fly around the machine.
Hi Chris. The drilling cycle isn't too bad without a chip break. IF I was drilling metals, it would be an advantage to chip break maybe every 4 or 5 millimetres. But, with plastics, it's possibly easier to run the drill to full depth and remove the chips later if necessary. It works out about every dozen or so cycles I need to clear the drill bit. I slow down the feed rate and spindle speed right at the end of the parting off cycle. It's more so the nature of Nylon, especially to get long stringy chips that don't seem to want to break off ?? IF I was running a Collet Chuck, this would stop the parts dropping down onto the chuck jaws and being launched ?? Out of this run of 300 parts, only 3 parts were damaged a little too much to include in the order. I usually run an extra 10 parts to make sure I am covered for when some of the parts don't work out so well. Thanks so much for sharing your thoughts. Peter 👍
Yeah, it doesn't seem like there's any obvious way to automatically clean up the swarf. At least the more complicated solutions might not be worth to implement for small batches.
Very true. For shorter runs, it's best not to overthink things and waste too much time trying to dial things in perfectly. A CNC Lathe for me is already a huge improvement over my previous set-up 👍
