I would like to know more about your objective with using our machine. If you use it for making PCBs, the CNC2016 is much better, because the vibration of the table of the CNC2520 is much higher then
CNC2016. The routing depth used CNC2520 is not stable.
Secondly, Do you need any drill bit? Because the spindle chuck collet is Dia. 3.175mm. You need to have some of drill bits such as 0.5mm, 0.6, 0.8mm, 1mm, 1.2mm and 1.5mm etc.
Actually, we use our machines to processing PCBs many times. CNC2016 and CNC 2518 (Working Table Moving)are the best for PCB!
We can share more information about PCB processing for you
Please tell us more about your processing for us! For business or hobby?
We have more low cost CNC machines for sell. We hope that a CNC machine should be suitable for you!
