Thanks for all this great info folks. I recently was told that for aluminum, Tormach does not recommend using anything larger than a 3/4 inch shank, and a one inch ball nose cutter head - mainly...

Thanks. Pardon my ignorance I am a newbie as far as machining is concerned, by the 17 or 25 mm insert do you mean an endmill with removable carbide inserts? Or a ball nose with removable inserts?
...

Sorry about lack of details I added more in the other two posts.

Oh so - you are saying I could get an oversized cutter that only has a 1/2" or 3/4" shank diameter for the collet. So you are...

Thanks for the info! So - I read in the manual that the machine is 1.5 horse, so I am a bit confused why the R8 is only rated at 1.25HP?...

So it appears then that I should not go over 3/4 inch...

Sorry I should have specified - I plan on using a ball nosed end mill, to machine aluminum plate.

Hi,

Does anyone know what the maximum diameter end mill can be run on a Tormach PCNC 1100?

Thanks.

A few questions about welding Stainless and also industrial adhesives.

It is my understanding that welding 303 stainless to 303 is difficult, but welding 304 stainless to 304 is a good material to...

Thanks for all the info last year awerby.

I am re visiting this..... so I am assuming that the 2 or 4 flute ball-nose endmill does not actually have a spherical radius to match my radius - and...

OK thanks....the rounded boss part would have the same radii on the underside.

Think this could also be done via 3D printing?

Yes...If what you mean by "Boss" is a support base for the top plate (not all that up on names of machined parts...)? I want to make a plate that has a flat surface on top of it, and the convex...

Hi,

Hope I am posting this in the right forum.

I have just a general question. I want to design a part out of either aluminum, or high density plastic and I was wondering,...before I do the...

OK thanks. So it appears that different towns have different codes in other words i1, i2 or LM HM etc etc.

Hi,

Hope I am posting this in the correct forum. If one wanted to set up a small machine shop somewhere between two and six thousand square feet in an existing building, can someone give me an...

Thanks.

What type of collet are the Porter cable collets? Is there a specific name for that type - the type used on woodworking routers?

Hi,

I have an application - I would like to use a porter cable style collet to both lock the collet into place such that I can position it anywhere along a long aluminum rod, but when loosening...

Hi,

Does anyone know what the taper is on a Porter Cable style router bit collet?

Also, are PC router collets the ER style of collet?

Thanks much I'll get one sent over within the week,

Just curious, with these 3d print processes what kind of material do they use? Are the parts made from plastic or high density foam?

Not sure if this is the right place to ask but I'll start here.

I would like to have some prototype parts 3D printed. I have recently heard about these 3d printing services, how does that work? ...

Thanks Geof will check that out I think I looked at a few sites last year but could not find anything, I will dig some more.

Yes that is exactly what I am trying to come up with...some kind of a clamp block that fits onto two rods.

For a clamp block to work, I would need to mount both rods to the block, and while...

No not a driveshaft. Just two rods on which a jig rests on. Jig sits on a table top.

I only need around 35 - 45 degrees max. The U joints would have to lock in place once angle is set. Can you point to an example of a locking U joint if one exists?

Hi,

I am trying to come up with a simple joint that will allow me to connect two half inch diameter aluminum rods at a 90 degree angle, and which allows them both to both rotate freely, and then...

Tonnage LOL. I am just trying to design a small table top jig for a tool I am designing. Tonnage is in a few pounds range at most :)

I need to be able to uniformly raise and lower the base of...

Does fiberglass rod lend itself well to laser engraving and machining?

I was checking out isopthalic polyester resin and E-glass rod from MAX-GAIN SYSTEMS, INC.

Yeah I was thinking about that, isnt that stuff expensive?

Yes actually I have, I was thinking though this would inrease the fabrication cost.

Would this be a cheap process?

Maybe I could buy such a rod off the shelf hmmm...

I assume you mean steel tubing?

For my application it might not work, I am thinking I need solid rod - there is a 1/8" bore in the 1/4 or 3/8 rod to hold another rod by locking set screw in the...

Hi,

I have a materials question. I am designing a jig and it requires the use of rod, either aluminum or steel- anywhere from 1/4 inch to 3/8 inch dia.

I had some initial prototype work done...

U mean EDM is generally more expensive?
