Anyone expierienced in Bungard CCD line of CNC machines?

bungard cnc

has anyone had any experience using the BUNGARD CCD line of CNC machines for PCB drilling/manufacture?

Thanks

First of all: YES I KNOW THIS THREAD IS ANCIENT, but as it appears in search engines I guess here is the best place to put the following information, to be the easiest way for people to find it. If any staff member thinks its reasonable to move the thread it's ok.

Well, we have such a machine at college, and just a handful of people have tried it, some just made drilling tests or something. My teacher had the idea to use the machine to make a PCB we need for a project, and we went on a journey along with the technicians at the lab.

First of all, I designed the PCB in EAGLE v5.8, then converted it to GERBER files using its CAM processor. Then, because there is little information on the web on how to use this machine (I attached a nice tutorial the technician gave me), it took a whole day (like 6 actual work hours) until we found out how to make everything fit and start routing the board.

After that, we used the included software ISOCAM to convert the GERBER files into HPGL files, which tell the machine where and how to mill copper in order to isolate nets, opposed to etching where you "save" the copper you want to use.

I learned how to adjust the machine's offset and configuring the software, then we found a fun fact, that the drill file (.TXT) was magnified 10X, so we had to scale it by 0.1
UPDATE: Actually, you have to configure "Drill Load parameters" in ISOCAM to match the ones you used to create the gerber file. I created it with 2-4 and leading zero suppresion, but ISOCAM read it as 2-3 trailing. So, configuring both as same solved the problem.

After that the technician taught me how to insert drill and router bits, and we made some tests together. I attached a couple of photos of the results.

Tomorrow we'll test again with the other configurations (layer clearance in EAGLE) and hopefully we'll have the finished board ready to be soldered.

Stay tuned!

I have a manual tool-change Bungard CCD .

I bought it primarily for drilling and routing board outlines after I put a 1.2mm PCB drill through the end of my finger.

I started drilling boards after wet etching but I found registration far better when drilling the board beforehand.

Well, I just came from college but found a "show-stopper" fact.

ISOCAM can generate the HPGL instructions based on which tool(s) you have, in this case: router bits.

The problem is, that other students just broke the smallest router bit (about 0.4mm) and left only the 1mm one. Configured that on ISOCAM and not all the apertures were traced (apertures are way finer than the bit). So, we need finer bits to make the board. We tested by configuring a 0.020" (0.49mm) bit they have at the lab, but it doesnt have the plastic ring so it cant fit correctly inside the spindle.

Anyway, as we need it soon we'll go to a research center near my college where they have similar machines (ATC ones) that can make double-sided SMD boards. My teacher has former classmates over there (he got his Dr. grade there).

I have some experience on the Bungard CCD CNC drilling machine. I have been using it for about 4 years now
