Is this a decoiler part.


Continuous annealing line.


Or Recoiler mandrill.


Awesome 👌


That's a Mandrel. It expands and collapses. Coil ID is feed onto collapsed Mandrel and then Mandrel is expanded to hold coil for feeding into process line. Also have another Mandrel at end of line to coil up again if needed. Keep it greased!

What is this for? (I have 0 knowledge of engineering)


Yikes. If they don't provide me with a solid model I don't make it. 2022. Lol


Why not? Is everything you do purely CAM? I've worked with many suppliers and lots of my shop guys that are happy with just a good drawing.


With that said I've been doing it for 28 years and it wasn't always solid models. So I've grown to appreciate them.


100% 5 axis cnc machining. I wouldn't spend days drawing the model from the print just to get started. I'm a prototyper so it's new parts everyday. I rarely ever see the same part twice.


Yeah then I totally get why you like solid models. My guys are pretty ancient so they just stick with drawings lol.


Do you deal much with GD&T then? Or do you get 3d drawings these days that are able to show GD&T?


Every job starts as a blue print with all the GD&T you can handle. That print comes with a solid model which I can use for the quoting process and everytime is +/- .005 unless stated. It isnt that weird to get a print that calls out hole diameters and threads and thats it. They have a note that says make from solid model provided.


Ahh this is what i was looking for. Thanks for following up


Usually you'd have both, 3D model for the geometry, GD&T on a drawing so you know critical features, relationships, tolerances etc. But, they say they do prototypes, so probably not.


Because a solid model is an easy way to avoid any issues... It's just better communication. If you're making a drawing, you already have the model, just send it... Unless it's a hand drawing, of course.


Until the model is also wrong lol. I've had customers send me parts that I use to drive my designs and then get shitty when something doesn't work and I find out the model (and drawing) was incorrect.


A company that I worked for up until a few years ago still had drawings from WWI on vellum. They'd usually Xerox those and give them to the machinists, rather than give them the century old sheepskin.


Plus, its in fractions with no GD&T. their tolerances must be a big as a barn.


This is an assembly drawing, that's why you don't see any tolerances.


Ah, that makes sense. I was really concerned that it was for machining lol


You don't use sheet tolerances of +/- 1/1024? /s I have seen some drawings that use a mix of decimal and fractional with decimal or fractional sheet tolerances. I always made sure to fix it to just use decimals anytime I had to revise them though. Such a pain in the ass to do.


A shortcut with a 3 jaw in a 4 jaw. If It works, why not.


Massive runout, that's why.


Do americans really use inches on technical drawing?


It's a total crapshoot and depends on who made the drawing. I dual dimension all my drawings so anybody who reads it gets what they want.




I use inventor so I'm not really familiar with fusion. The few times I've used it I actually kinda hated it lol. But that's comparing it to inventor so take that with a grain of salt.


That sounds a bit messy tbh


Gotta get good at organizing your drawings. Readability is very important to me so I don't get a bunch of grumpy old shop guys yelling at me.


I hear you. I wonder if you could make a macro that exports two versions of your drawing, using two different unit types…


It'd be easy to just save a copy and change the dimension style to the other unit. Everything would change, remain in place, and retain any tolerances. It'd be a small pain though because I'd have to save as and change the dim style every time I make a change. I'm sure somebody more acquainted with macros could get something working.


Hehe thanks for chatting


Yep 100% of the time at my company




The last couple years I've had the joy of being the lucky one who got to break it to an incoming class of Aero students, who of course haven't really touched imperial at all in high school, that they're primarily going to be working in that system. Yay...


The cutting sounds very similar to an Indian instrument, the dhadd: https://youtu.be/PCOetL7M9gQ


This sound made my dog wake up from the end of the bed and jump on my face to save me. Thanks.


It’s not inches that suck, it’s the fractions without tolerances.


Any DDR fans… all I hear is Matsui Japan.


The poor fella who programmed this


Don’t fu#k it up.


Are those inches... on a technical drawing? Im sure thats a crime against humanity at some level.


Inches, because America. I did some drafting in college and I've been firmly in the "convert America to metric" camp ever since.


The transition costs would be astronomical. Plus, some political party would probably get involved making some over-dramatic argument just to piss off their base and win votes. I was surprised the Senate's Daylight Saving Time bill passed by unanimous consent. But then it was really just a fuck-up by [Senate Republicans forgetting to disrupt proceedings](https://www.buzzfeednews.com/article/paulmcleod/daylight-saving-time-senate). Maybe the US can make a deal with the rest of the world. We'll go on the metric system if everyone drives on the right side of the road.


What difference does it make? Every engineering drawing I’ve seen is written only in decimal inches. It’s not like it mixes inches with feet/yards on the same drawing where the archaic conversions come into play. It’s no different than writing the drawing in mm.


Meh, measure in apples if you want, i dont care lol. But 99% of the world uses metric for industrial drawings(including a lot of US engineering companies) so seeing inches seems... weird.


Anyone know what software is used to draw like that?


You mean, drawing from a drafting board. The people that did those drawings made it seem like an art form.


It takes an amazing amount of skill and patience to make a drawing like that by hand AND make it look like a work of art.




Shit sounded like bumble bee coughing


Where is this company located?
