CNC conversion AMAT25LV AMAT30LV WM18 advice needed for total novice

[Hulksmash]

Hi Guys, along with designing a cnc router I am also looking to buy a milling machine.

I will use it manually prior to a CNC conversion.

I have limited space in my garage so the max sizes are the WM18 /AMAT25 /AMAT30LV size.

I have heard many good things re the Amadeal mils and them being belt driven and having a larger cutting area.

I basically have a rough idea re drivers and board but I get confused re spindle speeds.

Do you buy a seperate spindle and fit that with a VFD or do you modify the existing one. ??

Also is there a way to determine the ball screw length easy enough, and are they end machined at all ?

Where does the community purchase from ? Any recommended sellers at all ?

As I am starting from scratch I will also need to buy cutters, clamping and a machine vice so I am trying to keep the cost of items to a minimum but not hinder quality.

The machine is for hobby use only to make prototype parts in steal and aluminium.

The mill will sit on a pre built workbench.

Unfortunately I dont have space for Bridgeport sized machines.

Any help appreciated.

Thanks again

Mike
