EleksMill moving step
Hello. I am wondering about the minimum moving step size of EleksMill CNC machine. Is it capable of handling drilling of holes on a surface with distances less than 50 micro-meter?
@amirazimi.y The absolute accuracy of the machine is 2.5um but due to the use of a pinion gear and belt on the X-axis it's positional accuracy is significantly lower, around +/-12.5um or 25um total. This will depend on bit loading and other factors, so for PCB drilling (no side loads) you could well achieve 5um accuracy.
In any case those 50um spaced holes would have a 10% tolerance (best case) which should be acceptable.
