New build - Screw specification???

[HiltonSteve]

First of all I would to say thanks for some very good answers to my questions, this was what I was hoping to get and it looks like I am in the right place. You can tell straight away when people are pretending to know the answers and when people actually know the answers!

So what I am now thinking of using is the following, please bear in mind that this is my first build and I am still open to suggestions...

1- I will be using the driver kit 1 on the Zapp automation website - http://www.slidesandballscrews.com/c...e9ad8184c36c4c

2 - Drive screws - I will be using 16mm ball screws, not sure where from yet but if anyone has any or can recommend a supplier then let me know.

3 - Linear guides / slides - Open linear bush's with fully supported rails on X and Y - probably 16mm - again not sure of best source/supplier. Z axis, going for 200mm travel to allow for milling cutters and drill length variances with mechanical adjustment for larger workpieces (good idea jeff)!

4 - Custom designed frame made from aluminium plate, found local supplier with very good prices for material.

5 - Spindle - not sure yet, maybe looking at a Dewalt or Metabo electric die grinder.

6 - Software - Mach3 looks like a good package, downloaded the evaluation version and had a play with it last night with some good quick results.

Once I have decided on the mechanics then I will start the design process which I will be happy to share with everyone that has helped and even the ones who have not but are interested.

Everything will be drawn up in my 3D cad package (Solid Edge) and i will post my designs on here for evaluation and criticism! I know my machine will not be right first time (is anything) but I am hoping with your help that I can get it pretty close to something that I will be happy with.

Thanks so far to Kip, Lee and Jeff (smiler). Without your input I would have probably given up before i got out of the starting blocks....!!!

Oh yes, did I say I was in what looks like the CNC capital of England.....Derby!
