Cradle Base

Alpine Precision CNC machined this 6061-T6 aluminum traverser plate. The part is milled to exceedingly tight GD&T’s with a high cosmetic specification. This part is produced in mid-volume production for one of our SEM/FIB semiconductor client.

The finished part measured 5.584″ long, 5.454″ wide and 1.221″ thick. Multiple flatness and perpendicularity GD&T’s machined to .0002” and true positions of .002”. Our delivery/turnaround time was three to four weeks and we now produced ~50 units per year for this client. For more information on the CNC machining we provided on this traverser plate, please see the chart below or contact us directly.
