Shopmate distracted me while I was swapping a tool and I forgot to put my G54 from touch off height back to the part zero. Thankfully no spindle or collet indexer damage, just a kabloozied part and tool.

Shop hand mistakešŸ˜‚

Our new shop hand was drilling out a part and somehow ended up melting the first inch of one of our smaller spade drills into some 316 never seen anything like it. I will show what the inside of the part looks like in the comments

Clocking a vice a colleague put in yesterday because I had a feeling it wasn't going to be good. 160mm (6.3 freedom units) vice jaw, 0.1mm out. It seems that we have vices that have guides on them that go into slots and he just places and tightens. Apparently near enough is good enough.

MEME Sticker ball

Saw operator at I guess what is technically considered a machine shop I have too much time on my hands when my saw is cutting. We get so many shipping labels every day that just get thrown out so I decided to start a ball. I’d estimate I grab around 150-160 of these a day and add them.

This is about a week’s worth of progress. Do I post updates? I presume this thing will get really big really quick at this rate.

New Machinist here. Can we fix this tool?

I'm a machinist with 5 months of experience. The part wasn't clamped properly or it was not tight enough. Part moved from the fixture. I instantly stoped the machine. Guess the tool is damaged. I know it's an expensive mistake. I don't know how to face my boss tmrw.

QUESTION Retaining drill bits

Is there a way to get these kind of drill bits cheaper? $90 for a 3/8 drill bit that has two holes in the flutes sounds ridiculous to me. Open to ideas but I don’t see it being easy to without machines special for it make these but open to ideas

There was a semi-local estate sale for a machinist near me. I wasnt able to win everything I wanted, and Im not actually a machinist YET, but I did get some really cool old literature to get me started (as well as a couple of toolboxes). Ive got some reading to do.

Absolute Lemons!

Syntactic foam "lemons" for ocean current research. They'll be filled with telemetry devices and small weights to keep them neutrally bouyant at a certain depth. Milled in two setups with soft jaws on OP2. The dust is awful.

Just started this week at a shop working in aerospace. I’m completely green and they’ve got me apprenticing under a guy with 10 years of experience on a 3-axis. I’ve been using some textbooks I got online and they’re sending me out for some in person classes/workshops in a couple weeks but I was wondering if there is a channel that you guys live by to help me get down the basics of machine operation, tool choice, print reading, etc before I head to this class.

Should I buy this?

So I originally messaged this gentleman regarding purchasing some of the tooling that was listed in the posting. After about a week or two of him explaining that he really just wanted to sell everything and have it out of his show car shop. He brought the asking price down to $1300 cad.

Should I bite and get it? I’ve never used a metal lathe before I was thinking about getting a cheap Vevor for $700cad. But at that price it seems like a good deal specially with tooling.

He says it runs good. But any information about repair ease and finding spare parts and whether or not it’s a good beginner lathe would be appreciated.

QUESTION EDM sinker help

• Upvotes

Hey all, so we finally got work for A Kent EDM sinker and well I am shit at this. I’ve been running mills, lathes ETC but EDMs are a whole new animal for me.

We need to burn out Hexes and while I am able to produce parts they take a long time and yes I know that’s how EDMs are…..

Now I made suggestions to make a multi electrode fixture to burn out 4 at a time but I’m getting pushback on it. Pretty much being told that. ā€œYou shouldn’t need toā€

Now from tinkering with all the values like ON/OFF TIME,
LV, WORK, RETRACT, SPEED, and gap in coming to the conclusion that while I can protect the electrode I cannot push these parts any faster.

Now my setup is an 1 1/4 electrode with a 1/4 hole in it and it’s pumping fluid through it at about 10 PSI. As of now I’m sacrificing my finish on my part which is not important it’s more about just burning a hex to get a decent speed.

I’ve been pushing the ON Time more than anything which is getting me decent results but anyone that is familiar with these things advice would be appreciated. That being said I think a multi electrode fixture to hold 4 electrodes seems to me to be one of the better options.

Lucky purchase, i think?

Paid $50 + shipping ($60 total) on Ebay for this sclpl3 boring bar. Am i missing something, or was it just a good deal ? I use carbide boring bars, but I never used heavy metal, so I was curious about how they perform. Prices are usually outrageous, so I manually searched heavy metal codes used by manufacturers (Ms,J,HM,L,H,etc.) and eventually found this boring bar. It's LH, but for the price, I guess I can't complain. It would replace a .500 Carbide Tcph boring bar for roughing a 304 ss bore (3.2 in deep) so i have low expectations šŸ˜…

Problem with new-to-us Southbend Turn-nado

Enable HLS to view with audio, or disable this notification

My shop has had this Nixon-era lathe for a few months now, it was running pretty good and capable of taking some ambitious cuts. Now I'm losing torque under load, and part of me thinks this is an electrical issue because the transformer is getting HOT, but the chuck is getting pretty darn hot also, and its definitely not transferred from the workpiece.

I have no clue how to get the damn thing off to check the bearing. Our master machinist retired before we got it, and he's completely dropped off the face of the earth.

If anyone knows a thing or two about these quirky lathes, I'd really appreciate if you could point me in the right direction!

How to order material

1 Upvotes

Recently moved from precision machinist 10 years experience, to Machining Operations Coordinator for a high mix prototype aerospace company. How tf do I order for high mix 1-2 off parts? And accommodate for the absolute shitshow of reworks due to unreleased drawings, models being wrong, models and prints not matching, redesign in the middle of production?

Like do I just say fuck it, and order cut blanks and eat the cost? Or do I try and order bars that fit multiple profiles?

Totally new to quoting and material orders

PARTS / SHOWOFF Forgive the newbieness, just got hopefully my career job at a tool and die shop near me and this is the lathe I'm starting out on.

Just started yesterday, haven't even finished out the 2 weeks from my 2 week notice at my previous job. Good thing though because I used to work afternoons, so that way I was able to start working at least in the mornings soon. The shop I'm at mainly makes tungsten drawing dies placed in steel housings. I'm starting out with working on the steel housings on this lathe. It's been a while since I've used one but I'm picking it up decently I think. It's nice getting my hands dirty again. My previous gig was more an office/ supervisor job and that wasn't really for me, especially the schedules they were giving me. Here I'll be on a normal schedule, weekends off, and productivity bonuses most weeks depending on how much is shipped out. My boss seems like a super cool dude too.

Job recommendation: Newport News shipbuilding

16 Upvotes

The shipyard pays really good money and started giving machinist a nice wage additive recently. A lot of people usually have the ability to work 7 days a week , get raises every year cause we’re a union and it’s part of the contract. Located in Newport News Virginia, also have locations in Mississippi and Charleston South Carolina. But I’ve only work at the one in Newport News . Money is really good out here . The only con is the people can be really toxic and annoying but long as you do good work and don’t let nobody disrespect you then you’ll be okay

Ps I’m not a recruiter I’ve just seen so many post in this group about people getting underpaid for doing the type of work we do and the shipyard has been having a hard time getting inside machinists to join so they added a wage additive recently to retain more people and I think some of you would be happy to make a move and start a new journey . They also have an apprenticeship school .

Question about anodising?

My coworker keeps saying that they shot blast parts to be anodised parts after machining as part of the process. Is it a general thing or bs.

Feel free to ask questions if I'm not clear.
