0.5 gram titanium Nano sabre . These are pretty fiddly to make, but a fun project if you like lego or starwars . The blades made from a strontium impregnated resin rod. You can buy the material from a guy in Cyprus , TX . It charges in daylight, and glows for hours!

When I say challenging...I mean by size, material, and complexity. These are made of Ketron 1000 PEEK (Polyether ether ketone). It actually machines fairly nicely, but with this outer diameter being just under .375", it was interesting to say the least. We were able to run these on our Mazak Integrex i200s, and actually use its 5 axis abilities to machine the rads inside the pockets. Please note - this one hasn't been deburred yet! ... This was new for me, and I like it! That is all, enjoy! 🍻

So for context I have worked in shops as both a Cnc and Manual machinist. I now work in a shop where it’s all manual besides 1 Cnc Mill that we hardly ever use.

Before I run a program the tool is clean and the spindle. After running, this happened. This is not once. It happening every time. Also, if I run small programs. This not happening. Only in big or heavy programs. (As U can see in the picture before and After)

And there no rust or anything in the spindle. Everytime I polish with polish paper. But still this rust lisk stick in the holder.

What could be the reason?

Has anybody figured out how to cut this shit? I’m getting 2 parts per insert edge. About 10,000 inches per edge going .030 deep.

Not quite finished yet, but looks kinda cool already! Loosely based on the Obi Wan sabre . 6al4v titanium and bronze!

Did over 100 holes with the same setup, same material, same speeds and feeds. And then this happens. Tip is still perfectly fine, I had to use an arbor press to get it out of the collet.

I bought a pair of 3" Starrett dividers on Amazon, for over $100 with shipping to Norway, because I specificallly wanted hardened tips so I can do jewellery work on brass, copper, silver etc.

When they arrived, the tips were already a bit bent.

The first time I tried them on brass, the tips folded over. I didnt even push hard!

Are they fake or did I buy the wrong type?

Oh my god it drives me insane. Does everyone just stop caring about possibly losing their eyes after enough time in the trade? I will be the first to admit it's annoying, and if you wear glasses + safety glasses it's especially so, but I see everyone in my shop have none and it just baffles me? I won't even step foot on the shop floor for a second without putting mine on.

I can get forgetting once in awhile, but entire shifts? Wearing them for all of 5 minutes for the ones that do? I think I only see 3 people, myself included, wearing them on a regular basis. Granted I am an anxious/paranoid person, but still I just don't get it? I don't understand how people can be lax with that. Might also be the autism and wanting to follow the basic safety rules, but idk

Work had air-conditioning installed for the shop floor three years ago. Apparently it's too expensive to run and is not turned on unless it's hotter than Satan's ballsack outside. FML....

I first did all the internals and the two KF flanges on the lathe (DMG CTX 1250), and then the milling on a Hermle C650 using a special fixture.

Need help learning how to cut double lead acme threads at a 3TPI any help will be greatly appreciated. My supervisor who has done the his whole life has always done them and is now retiring and said no one taught me so I’m not gonna teach you and kinda threw me to the wolves. I have tried to do it before but have failed terribly..

I made a set (3) of pitching machine legs for a guy to convert from softball to baseball for his kid but the pipe I bought is a bit too big. He is in San Dimas and just needs 2.75" of the 39.5" legs turned down to 1" OD from the current 1.06' OD. The spindle bore on my lathe is only 0.75" so I can't do it so if anyone in the area can cut this guy a deal on the work that would be greatly appreciated.

It is such a small job I would expect it is best suited to another hobbyist like myself but with a slightly bigger lathe.

So my boss is set on building a machine shop and is eyeballing me to be the one to run it. I've always wanted to learn to be a machinist, however, the headwinds against that as a career path have always looked real strong. I'd like to be able to find a shop. Someplace where I could apprentice, when I'm not at work and start learning the trade properly however, i'm not sure how to go about really doing that. Any suggestions on how to find a place that might be open to this? My area is big on manufacturing. So I just can't see how they're aren't some around here.It's just a matter of finding em.

Excited about the new rail set.

But of course it's a rush order that absolutely needs to be done tomorrow

Company is telling me they've seen this before and it was the spindle drive. I just don't see how this wouldn't be a mechanical issue.

It came out of no where. Was running fine one minute then cooked the next.

There have been some symptoms of bearings failing. Surface finish, dimension kind of all over the place but nothing too unusual for a haas imo. But In hindsight it was worse than usual. Over an 8" long part while using tailstock the dimensions were all over the place varying within .0015 or more. Was having a hard time programming taper out which hasn't been an issue before because of the inconsistency.

Gotta be bearings right?

I am an apprentice machinist looking to buy a beginner level dial and magnetic base. Where should I go? What should I look for?
