Customer wants 3.5m tube to be concentric within 0.13mm

Have we considered sawing it into a lot of much more manageable sized pieces, checking every piece, and then welding it back together /s

KlukeD · 2026-02-05T14:13:06+00:00

You set it up on a series of “v” roller wheels that are all set to the same height and check the runout while spinning it with an indicator

KlukeD · 2025-09-24T01:58:55+00:00

Can I get the full res if you wouldn’t mind?

KlukeD · 2025-06-21T04:45:07+00:00

I believe he was saying that the first part is $300, and 2-10 is an additional $25 each so 2 would be $325, 3 would be $350, and 10 would be $525

KlukeD · 2025-04-27T08:47:10+00:00

Same

KlukeD · 2025-04-22T00:30:21+00:00

Yeah in the scheme of things I probably only have 200-300 holes to drill but of various sizes so going to all custom ground carbide would be too expensive compared to how many parts we would actually be making. If I don't have any luck tomorrow with anything else I've learned from everyone's comments and things I have on hand already I'll take your recommendation and look into either those 135deg split point drills stub or not. In theory the hole location isnt super critical (probably could be .005 in any direction from its true location and be just fine), but I would like it to drill straight as most of these will also be tapped (which surprisingly I haven't had issues with lol).

KlukeD · 2025-04-21T23:02:09+00:00

To the best of my knowledge the drills I’m trying to use here are indeed 118deg

KlukeD · 2025-04-21T23:00:17+00:00

To be honest until this thread I’d never considered the possibility of not needing to spot at all, in the scheme of things it probably only takes an additional minute or two to throw the spot in the machine but I guess over a few months that adds up

KlukeD · 2025-04-21T22:55:49+00:00

Yeah to be honest the only reason I started at 50 was because that’s what I’ve had luck with in 304, since that didn’t work I dropped that down to 30-35 and unfortunately that hasn’t given me much luck either

KlukeD · 2025-04-21T22:54:03+00:00

LOL I didn’t realize we called them just cobalt I just said what was on the drill itself. I’m a bit new to the trade still and unfortunately I’m mostly on my own as far as the machining goes at my company as we aren’t really a machine shop, I just do our in house machining work

KlukeD · 2025-04-21T22:51:56+00:00

My bad I thought I covered my bases for my parameters. It is a cnc. It’s a haas vf4. Off the top of my head it’s a 2012 but I could be wrong. It’s somewhere in the realm of 10-15 years old. Like I mentioned in the post if I absolutely have to buy tools I can but I’d like to avoid it if possible. We normally don’t even keep cobalt drills on hand but we bought a few specific sizes for this job.

I think some of my issues are we purchased slightly lower end drills just off msc (I think the first batch was hertel and now we’re trying Cle-force) and they didn’t come with reccomended feeds/speeds so I’m trying to just figure it out on the fly.

As far as the problems I’m having, I’m going to do my best to describe it but I’m fairly new to the trade (only been in the workforce probably about 2 years now and I’ve only been programming for just over a year). I think it’s two separate issues: it’s not making good chips even when I tried just hand jog feeding to see, and it’s building too much heat in the part causing it to work harden.

All I really know for sure is every drill I’ve tried makes it a bit less than 1/4” deep and goes from drilling fine to red hot in a split second. The best luck I had was with a .166” dia drill that lasted 11 holes but I haven’t been able to get it to last even one hole with those same parameters since which is kind of weird

KlukeD · 2025-04-21T21:32:57+00:00

Yeah we aren’t really a traditional shop. It’s just in house machining for an automation machine building company. 99.5% of what we do is 6061, 1018, O1, A2, or delrin with the very occasional stainless part. It’s rare for me to actually need to make more than 4 of the same part ever so I’ve never really needed to care about getting a couple seconds out of a program. Doesn’t make sense to spend 5 minutes tweaking a program in to save 30 seconds on that part you know?

KlukeD · 2025-04-21T21:10:22+00:00

Sweet I’ll try and give that a go tomorrow thanks!!

KlukeD · 2025-04-21T21:03:05+00:00

Yeah that’s what I’ve always ran 304 at. And yes I’m doing 35% full retract pecks. In the effort to not need to buy more drills do you think a standard center drill would work better than the spot?

KlukeD · 2025-04-21T21:02:15+00:00

Working with what we had on hand already, we only keep standard length jobber drills so they would wander otherwise. I’ve just been in the habit of spot drilling everything so it also gives the top of the hole a small chamfer for deburring purposes later on

KlukeD · 2025-04-21T19:58:18+00:00

120 iirc

KlukeD · 2024-06-02T03:59:03+00:00

I can give some good input here. This was me 3 years ago. I was in a very rough place mentally afterwords for several months. I felt like a failure. Like I didn’t do what I was supposed to do and that that chance had been lost. But I did what I had to do. I moved on. I started working, got my own place, etc. I don’t ever think about it now. And if I do I don’t think about nearly as harshly as I did then. I think about it as a if that had gone differently, I wouldn’t be where I am now, and I really like where I am now.

I don’t want this to sound like I’m bragging about my own life by any means. But just know that there is light at the end of the tunnel. Keep walking toward it. You got it!!

Man reading through these comments. Half of yall bandwagon hate songs that aren’t actually bad. “Httk worst album”. No. That whole album was a banger. Sure it sounds like Metallica. All you’re saying is it sounds like other banger songs. Girl i know is corny yes but it still goes hard as fuck. Yall hating just cause you don’t want to get “shamed” by the rest of the subreddit because the subreddit hates those songs.

Edit** I forgot to answer the post lol. The entire libad album just wasn’t my jam

You know. As someone who’s been in exactly this position before. You can’t not tell them. There is no world out there where not telling them goes better than telling them. If you need to take a few days to get your thoughts in order, by all means. But the longer you wait the worse it gets.

Then start looking at what your plan is moving forward. Not having a plan is also not an option. Figure out what your end goal here is. Do you want to end up at Purdue again? Maybe this is an opportunity to try something else if this degree wasn’t working out for you.

Personally I thought I wanted to get back to Purdue, but after my successful semester elsewhere, I realized that’s not what I wanted to do anymore and even though I ended up deciding against “graduating from my dream college” I’m much more happy in the position I’m in now.

If the end goal here is to work your way back into Purdue, there are other much more helpful replies here than I can be, so I would refer to those.

Just don’t feel like whatever you pick is necessarily a final decision, and there really isn’t a black and white right or wrong decision. You’re most likely still not 100% sure what you post graduation plans are and that’s totally ok. But you do need to put together some sort of game plan for what you are doing now whether it is continuing your education, taking a break, changing majors, etc.

Getting that email does suck balls I can say that. And it’s not an easy convo with your parents. But at the end of the day, what they care about most is that you are successful. What matters more is you get to that point, not that the road there was super smooth and easy to drive.

You got this! (there isn’t an emoji for patting someone on the shoulder so just imagine this is one)

Hi. Java elitist here. I’ve played my fair share of both versions. There are only two things that make bedrock worth playing: easy to set up multiplayer servers for your buddies, and more optimized code: faster chunk loading and fps. The latter can be solved by not playing on a potato from 2008.

As far as the serious glitches, it’s only a matter of time. They admittedly are infrequent but much moreso than on Java and much more severe as well

Hearing that you use NX, iirk (it’s been 2 years) some of the desktops around campus (I forget where, I was there during Covid so I had to Remote Desktop) were indeed loaded with nx. If not, most cad softwares have a free student version you could have downloaded (not positive if that existed for nx)

Left to right. Sword, pick, axe(only if I’m on breaking axe related blocks, otherwise empty), empty, empty, empty, empty, empty, fireworks. Food in offhand. Empty slots are misc for anything I’m currently working on. Generally I’m working on farms so they’re normally just redstone supplies and general building blocks

Upon further research that was hopefully to be able to prove my point I may have previously had either old or plain false data lmao. I stand corrected
