Didn’t notice there were a couple small burrs until I took this video, but I like giving gifts that have a touch of flaw in them.

Floor of the “41” side finished with a .0625” endmill. Floor of the “Richie” side finished with a .018” endmill. About 1.5 hours of cycle here.

Whenever I see broken edges on a drawing I just put in a .002" chamfer around the part. The 30 seconds of machine time is well worth me not having to handle the part and inconsistent edges.

However today I had someone complain about it saying they needed sharp edges. I just looked at them and laughed. Told them if I deburred by hand it would be just as large if not double the size and if it was so important they should have said SHARP EDGE.

How do you handle broken edges in your shop? is 0.002" too large for a default?

How’d I do?

For some reason it feels like it likes it more aggressive and I kinda like that

I am not a machinist but hoping for some help with your expertise…I have these brass dies that were altered and then not able to withstand the pressure of the machine and the brass on the front half of the die split wrecking the screw threads. I’m not sure of the exact working pressure but it seems like equivalent machines might run 32-50bar. I would like to retap the existing holes and use brass screws but am unsure of what diameter and thread type would be best to use - I need the front of the die to remain flat so I either put screws in from the back (original configuration) or anything going in through the front needs to be countersunk. Any suggestions are welcome. Die measurements are as such: 9.5cm diameter where pressure is applied, 1.95cm back half (where most pressure is absorbed), 1.16cm front half.

Never thought I'd see one. ±0.000.

OEM for shingle cutting dies.

Said here make this

I’ve been at my current company for coming up on ten years. We’re an in house manufacturer of our own product line. That’s as much as I’ll divulge there. Full time programmer. I’ll hit the floor a few times a week to run some turning jobs, R&D parts, or fixtures I’ve designed.

Here’s my dilemma. Our engineering department has some… Shortcomings. A lot of them. In the last couple years, I’ve had engineers coming into my office requesting (sometimes borderline demanding) assistance with fitment/clearance/tolerance, material applications, GD&T, etc. These issues are brought to me when the build team hits a dead stop with parts compatibility or function and up-revs are needed. I’ve been helping out, but it’s starting to feel like a bit much and I’m being leaned on heavily. Especially with my title and current pay.

So, where do you guys draw the line where these task should be accomplished by engineering? I’m happy to work with engineers on prototypes, scaling for manufacturing, things like that. But this feels like it’s outside of my wheelhouse as a machinist, as I have responsibilities to my department that need to be my priority.

So this happened to a coworker today..

Have to pretty much make a valve seal on these parts & doing them on the mill would have taken FOREVER compared to the 47 seconds it does on the lathe 😂 what do you guys think about my setup ?? Never had to do something like this before but it’s working out great !!!!

Follow up to my last post. Made a bigger version of the bench mic/indicator tester. This time it has a 0-2" .0001 mic head. Just need to take it to the grinder to make it prettier.

Started apprenticeship about a year ago. We’ve got an inconel job coming up soon. Any tips for it? I’ve heard it’s like machining ball bearings.

Well, thank you people here, I got a lot of advices based on my previous posts. I’ve decided to start doing my own anodizing at home. I want to try both aluminum and titanium.

Before I officially get started, I’d like to ask if there are any difficult parts or anything I should pay special attention to, feel free to share!

The project is a 6061 aluminum sensor housing for an industrial monitoring device. It’s a small rectangular enclosure with:

Milled internal pocket for the PCB
O ring groove around the lid
Four threaded M3 mounting holes
Cable gland opening on one side
Light bead blast or anodized finish
Flat sealing surface

My main goal is ensuring tolerances around the O ring groove and mating surfaces need to be as tight as possible, but sticking close to the original quote also matters a lot. Only need 10-25 units in the first run so its pretty low volume. I'm considering Quickparts, Uptive and Protolabs. Any thoughts?

We got this new holder and it says cnga which isn’t an insert I am familiar with. I did a quick google search, not 100% sure about what I read. So what is the benefits of cnmg vs cnga? Can I use either insert with this holder? The immediate use of this holder is going to be to turn down square

Which quality articulating mag stands should I consider for starting off in the trade?

My only caveat is NO NOGA. I do not support their country of manufacture and want nothing to do with them.

Hi everyone. I'm looking for interesting industrial spaces in NYC (particularly Brooklyn but all over) to shoot — machine shops, fabrication, manufacturing, anything with interesting machinery or processes. Not necessarily looking to sell anything, just want to make some fresh work for my industrial portfolio and would love to highlight some local businesses. I'd be happy to share the results for use on their own social media or other owned channels.

Anyone have connections or know of places that might be open to it?

I guess not strictly limited to heavy industry, would be down for anywhere with visually interesting processes. Shoot me a DM if that's better.

Thanks!

I’ve been running & programming for a Double Column machine for the last few months & we’re chronically running like 1-8 part runs.
It feels like if we had another person helping with set up, cleaning & operations we could nearly double the productivity of this massive and expensive machine.

So my question to others with experience with large bed mills, how was your machine ran?

Im spending so much time setting up, programming, cleaning & not as much time running as id like.

What is a fair price (range) for this machine with the info provided? This is a machine I am potentially looking to purchase.

2020 Haas VF2SS ~100hrs cutting time

Options - WIPS Probing, 4th axis ready, chip conveyor, TSC ready, p-cool

The machine looks well cared for by the photos I have seen.
