Yeah I will probably end up using a washer/bolt combo. I see now that the should shaft is generally ground for accepting motion components, hence the spec and price. I'm surprised a lower quality alternative doesn't exist.
Im currently spec'ing a project and I need what is essentially a shoulder bolt. How come these things are so damn expensive? is there a tolerance spec that I'm missing?
Thanks for all the advice and help on this matter. I eventually gave up on the idea of heli-coils as it became clear this would not work. The solution came in the form of a thread reducing insert provided by a company called memfast.co.uk.
The process involved drilling the hole to 5mmØ...
Hello All,
Ive made a rather stupid and annoying mistake when specifying a tapped hole which should have been M4, but is infact M5. Am I right in thinking I can use a m4 helicoil to reduce the size of the thread. I know this is not the typical use for a helicoil but i'm in need of a solution...
Hello All,
I am struggling to find the most useful way to dimension two holes that extend from an angled surface. I have a wedge shape, with holes extending from the flat bottom, and two extending down from the top angled surface (see image attached.
What would be the best way to show the...
Hello All,
I am trying to run a simple simulation on an aluminium part bearing the weight of 54newtons on a single flat face.
I have my materials correct, and my fixtures are fine. Yet no matter what values I give to the force being applied, or the type of material used I get the same...
The part i am looking to create is a very organic form. No straight lines or true radius curves. The company we use are not able to interpret the 3d CAD, and i am unable to express it through a drawing. so I am really trying to simplify the process and give them only the data they need.
Hello All,
I am looking for a service to create g-codes from a solidworks model.
I have had play with BobCAM for Solidworks, but what I would really like to have this as a service i.e I submit a file, I receive a set of instructions for a particular CNC machine.
I see that the software is...
Hi Dominik,
The issue with my part was that I had added an extruded cut, it was the number 4. The center of the 4 was treated as a separate body. By removing the text and adding again when I had the bends correct it worked fine.
In short a feature before this is causing the problems, try...
Hello All,
I have designed a part in SW 2012, using sheet metal. Its a single body part with 6 folds. I have been working on the design with no problem. Now when I load the model and try to add a sketched bend or flange I get the message "The selected Entity does not belong to the sheet...
Hello All,
I am trying to find the name of a product, or part that looks and behaves like the image attached.
Basically I know these Exists but cant think of the name.
I have a fixed object, and another which is pivoted on the peice and moves radially. One of each would be bonded or fixed...
DiegoLGraves - thankyou for the explaination, I asumed that this kind of operation was a little simpler, who knew engineering was confusing!
Yes this seems to be the answer I am finding more often. The problem is there is a lot of people between me and the guy who bend the metal, when talking...
Thank you up draft that's brilliant. I'm going to convert to mm and see if I get some more desirable results.
If I end up with something useful I'll be sure to post it on this site.
I'm still at a loss as to why this isn't a standardized thing!!
Again thank you very much!
Thanks Jboggs,
Due to my limmited engineering knowledge I will leave the files until i have something solid to work from.
I think getting the sheet metal folders to give me some set-dimension examples will enable me to base a new bend table on the output. I cant beleive there isnt already...
Hello All,
I have been using Solidworks to develop sheet metal parts for around 3 years now. Until now I have been relying on the preset bend and guage tables.
All was fine until we moved laser cutting/folding company and now they are reporting differences in achievable bends. Its causing...
As I expected really, the use of the bolt is more of a passive fixing, it bears very little weight. We have been cutting them down. It strikes me as odd that i can get a csk bolt who's threaded section is only 4mm, but not a dome head version, I think ill have to look into getting them made...
I know this is a rather benign and add simple questions, I am looking for an M6x4mm done head alan bolt. I am struggling to find anything under 8mm.
If anyone knows of a company that produces bolts in these sizes it would be very useful.
Many Thanks
Hello All,
Im sure this isnt the correct sub-forum, however I am looking for a specific type of bearing, and I trust the collective knowledge of engineers more than google.
I have tow plates, one stationary at the bottom, and one at the top that is allowed to move freely. They are both...
Thanks to you both for the directions to the correct forum. It would seem that the hole callout for metric machine screws doesnt by default contain any specification regarding thread pitch. For those who wish have this information in the hole call out for a holewizzard hole - simply add...
