What are the conditions under which parts cannot be CNC machined?


1. Inner right angle. Because CNC milling cutter is cylindrical shape.  When the inner wall of a part is cut, it will leave a radius on the vertical Angle.  Although you can reduce the radius of the tip with a smaller diameter tool, you cannot make an internal right angle.



2. Thin-walled precision parts. In CNC machining processing, thin-walled is difficult in processing and be easy to deformation or fracture.
