PCB CNC machine
Re: Second Hand PCB CNC
A few months ago I was facing the same choice and got A360 (accuratecnc)wormsmith wrote:I almost have the boss talked into a PCB CNC/milling machine at work. We really need it! Is there any good place to find a listing of second hand machines from LPKF, Accurate CNC or T-tech? Trying to keep cost down but also looking to get auto tool changing, vacuum table, enclosed, 8 mil and camera if possible. Two layers will need to be done on the machine. Please send any recommendations, previous experiences etc. Thanks for any help.
Initially I looked at S62 (Ebay) but it went to $21K, same configuration new (according to the seller) was over $30K and the machine was only 18 months old.
Another try was C60 (6-7 years old) for $7K (worry about the age, mechanical worn-out,geometry, software) so I decided… new A360.
The decision was right. I am using it for 3-4 months it works fine. So far I have 30+ boards and some stencils made with ZERO problems.
If you are looking for used machine, better check for factory refurbished by manufacturer (LPKF, Accurate CNC).
P.S. Initially S62 was my dream due to the auto tool change (ATC).
Now I know that this option is not essential to me. Tool change is easy and fast on A360, I saved money and don’t need a compressor in my room.
IMHO ATC is significant advantage only for production applications (let say drilling of many boards)
The PCB on the picture was made entirely with the machine.
The drilling is the simplest operation
. Up to 40 mill holes are drilled with drill bits and all above with router, so there are no limits to the diameter .
This way also provides savings for tools and tool changes.
The smallest drilled by me are 12 mill. If someone is interested.
There is a demo software that is running without machine http://www.accuratecnc.com/download.html also the manual is there.

Here are images of the double sided test PCB from the AccurateCNC 360 I had made.

I went nuts and scanned it at 600dpi
So here is a zip file @ 33MB for those who want a really close look.

Accurate machine seems super awesome. Can anybody share their plated hole experience or setup for this or similar machines? Methods other than placing a wire and soldering are appreciated.

Re: PCB CNC machine
There is an easy way to make through-hole connections on homemade PCBs. Check out the snap-off
