I'm in the same boat, got a 6k4 and from what I gather from the reps at Parker you will not be able to translate 5axis simultaneous motions or 4 axis sync motion with the 6k series controllers. Acro...

I already converted my X3 to CNC however I could always offset in Y by adding a shim bracket to the motor mount bracket. I have a set of THK HRW27 rails lying around that I was going to use on this...

I've been planning on remachining my column in order to accept precision linear rails and bearing blocks to bolt the head to, there by eliminating (to a certain extent) the slop from the gibbs....

Well just thought I'd share some results of the diamond turning process. Verified with white light interferometry, I got 12nm RMS on the surface finish. Not bad, but could do better.

I'd like to thank everyone for their feedback, the part came out looking really nice, however there's still a diamond turning process to complete on the parts main face.

Any suggestions on...

I've had really good sucess machining polystyrene and polyethylene (glassy polymers) with single crystal diamond endmills. Due to the edge radius of the tool being in the 20-50nm range, which means...

Thanks guys for the tip. Actually one of my co-workers recommended the same thing. Cutting a flat on the leading edge.... he says that it works well on plastics as well when popping a through hole. ...

fuzzyracing... thanks for the tip on dulling the leading edge, I'll remember that one.

This material is very forgiving and I love the way that it cuts. We got the brass from a specialty source in...

Would high helix angle tools work well with this material (milling), also what angle would work well in terms of drilling?

We machine alot of Cu at work and the best tool for the job "albeit quite expensive" is a single crystal diamond endmill. I've gotten 20nm surface finishes with it before, verified on a white light...

Just as the title states, I'd like to get some recommendations on milling/drilling and reaming Brass 360. Cutter selection, machine parameters, tool geometry and such. Thanks.

Thanks for the info- I went with the Nema 34 Powerpacs. I'll let you know how it goes.

No one?

Hi, can anybody recommend some Nema 34 steppers with this particular driver

I'd like to acheive more translation speeds and cutting force,...

Thanks that was helpful. However, how do one check the to make sure the machine mech/electronics is in good running condition? Good alignment of the ways. Alignment of the spindle/runout and such....

I am contemplating about buying an old VMC for short production and prototype work. What procedures should I run the machine through to make sure I don't buy a lemon?

What packing grease should I use for my NSK angular contact bearings? Thanks

Thanks for the advice Davo, but buying a tormach (albeit a really nice machine) really defeats the purpose of me learning the intricases of designing and building one for myself, even if I have to go...

As for the spindle what options would I have in upgrading to a higher reving unit? Cutting at 2000rpm with micro endmills would be painstaking at best.

Okay guys and gals I need your superior wisdom and knowledge on how to get my process of CNC'ing a G0519 mill (Grizzly) started. First I would like to start by asking if anyone would have a better...

I work on a Kern Micro Milling Machine at work that has a repeatability positional accuracy that is in the micron. It's servo driven with a heidenhein glass scale with an acurracy of .1 Micron. Kern...

Well basically the q parameters are used as variables, for instance instead of a L X0 to L X5 you would simply define q values such as Q1=0 and Q2=5 and substitute the X moves to L XQ1 to L XQ2....

Just what the title says, anyone have a generic post that I can edit to be machine specific?

Also forgive my ignorance but does the machine defs and control defs effect the way the code is generated? So in effect if this is true you can effect the way the post, post out code by changing the...

So there's really no good literature on this topic other than the reference guide? I saw some information in the MCAM9 Getting started book but it was very vague and gave no clues as to the...

Hello everyone, I was wondering what is the best approach in learning how to write MC posts. What language does it use and where can I find information regarding the conventions of this programming...

Well I've been looking to purchase a machine in my area in and around Southern California to keep the cost of freight low. I've seen some machine dealers of used machines in Santa Ana called PM...

Thanks everyone for the advice. I'm really not in a hurry to jump into this as I rather take my time and not rush this sort of commitment, as I've got lots of considerations. I mean there's shipping...

What I meant by CAD/CAM capable was the ability to DNC through an RS232 port as I know machines that old would not be capable of supporting ethernet I don't think.. I will do most of my programming...

And I'm really not looking to put these machines into production, just more of a very capable machine for hobby and learning purposes (for now). But one requirement of my is that it must be CAD/CAM...
