Does anyone know of any CNC lathe shops that would be willing to do a 1 off prototype small parts?

Or anyone that would be interested in small project that has a CNC lathe available to them?

why does some one need a CNC just for a one off part, and are you wiiling to pay the time needed for programming. So what are you thinking of haveing made, the pic should make my point

agreed CNC programming for a one-off part is silly. manual milling is definately the way to go. WHat exactly are you looking to do? I'm a machining student and occasionally have some spare time in class.

I need to build something similar to this.

To make it right I think I will require a CNC IMO.

But I am open to suggestions if you have them!

I don’t know how I would get the kind of geometry I demand without using something as precise as a CNC.

If someone has some suggestions please recommend a solution for cutting a profile like this, on a standard machine.

I wanted to say thanks to Chuck as well, he helped me with a technique to get closer to the dimensional profile I was looking for! Thanks for taking the time it was appreciated very much!

Would someone care to enlighten me to exactly how much programming work would be required to make a part such as this?

This is not what it is really going to look like, though it is a good interpretation of the profile I will need to cut. I gets a little more involved.

I hope to actually produce a few of these if they turn out to work, so I am going to have to make a few prototypes, just to see if I can get the thing to work for my purpose.

I had some knurled shafts made up for some homemade scooters I used to build. It cost $1000 for one part or $250 for 30 parts. its gonna depend on the metal your makin it out of. wheather its hollow, how big it is, if it has threads, if you want it polished. is that the tip of a rocket?........um never mind

The part will be made of aluminum just to see if it is really going to work.

What is required to program a CNC to do the cutting tasks? I have always been under the impression that the machines have the capability to generate programming from a model, and a known material telling the machine how fast material can be removed.

Is this not the case?
Can someone with a grasp on reality tell me a little bit about this process?

If everything goes to plan I believe I can sell many of these parts, making it much more economical in large lots I am sure.

Who did the work for you?
Are they easy to work with?
Are they willing to work with you on the project, to make it turn out better?
Any contact info?.

Actually it is the rear cone off a seadoo pump.

It looks simple enough that you might be able to make your prototype out of wood with a wood lathe to get your dimensions and fit down,, and then take it to a machine shop to let them look at it. The part could be cast and then machined or milled. The machine shop could let you know what is the most cost effective. I have heard of a foundry in Spokane that does turbo housings(who would have thought) You should check into getting a pattent app too. It looks like a good idea.

foundary=castings. to get a rough shape. nothing anywher eclose to precision. though most foundaries have other capabilities as well.

And yes if you want possible repeatability, CNC would be the way to go. At the moment I'm mildly clueless as they won't let me play with the CNC's until next year, but I could likely hand-spin something for you if you'd like to test it out. I'd assume you've got some vital dimensions and the rest of the shape is just kinda rough and theoretical? Unless you've got some specific aspects of that shape that are vital to your design, I'd definately got for manually turned protos. cncing prototypes is indeed Spensive.

I have been a cnc machinest for about ten years now, but am now running my own business although I still have access to machines. You will need a cnc to acuire the geometry you are looking for but machines do not do this on there own, they must be programed in G code and you must input proper speeds and feeds for the material you are using. Some cam systems can input this info for you based on drawings if you have the proper setup for a certain machine but you still have to tell the program lots of info to make that happen...

I can help you with your project and can guess by your drawing that you will have about five hours program/setup time to cover and then time and material cost. If you are prototyping this and want a few differant versions to try I would reccomend getting each design change nailed down before you get them maid, as small changes to the part should be fairly easy once setup in a lathe.

Let me know if I can help

What type of program are you drafting in? You will also need to look at the type of maching that is being used. If you have a compatible match there are certain combinations that will do the decoding for you. If you can avoid entering it by hand I highly reccoment that. Leave it to a machine the accuracy and precision is much higher.

I personally would use a CNC. But that is just my **** retnetive nature sticking out. Better to be over precise rather than have a part that is off spec. Not to mention if you are going to be producing these and selling them.

BTW that is a funy looking cone filter...but hey guess it will match your car

Do you have any information for this foundry? Very interested if they could help me with another project.

And I would love to get a patent on designs and ideas I have, unfortunately from what I have read about the topic it is hardly worth the effort, what with the cost of filing and the time, let alone the attorney costs when/if it is challenged unless you really have something good in your hands.

I am so small time, it really doesn’t make it worthwhile unless you have the means and rely on you intellectual property for you source of income IMO.

Hey Justin, I am interested in any help I can get honestly! If you are willing to help I would be very grateful.

If you want to PM me some contact information, and a good time to bug you, I will call and maybe we can figure something out.

And since you are a machinist, maybe you can tell me a little about the impracticalities of building such a thing us designers commonly miss!

I know of a guy in portland that has cnc equipment is very reasonable in price. He makes parts for me all the time and will do one offs.
