A robotic arm includes a driving unit, a first arm assembly connected to the driving unit, and a second arm assembly. A stacked ceramic plate set with a wire band received within a groove defined by a smaller height intermediate stack insert is a suitable substrate. An axial support configured to prevent axial compression of the ring and to permit radial deformation of the ring is received in the tube in a second circumferential segment of the ring. The motor mounting arrangement is configured to mount the motor to the outer cylinder such that the motor floats within the motor mounting arrangement. If not, the system sends a file to the customer graphically indicating which portions of the part need modification to be manufacturable. With the NC processor, the Y-axis cutting tool is mounted on a sliding base above an X-axis table in a way allowed to move back and forth in a Y-axis direction, while a grinding unit is installed in close proximity to the sliding base.
