Considering the thin wall thickness 1.0 mm and big dimensions (L×W×H) 260×160×8 mm, keeping size stability and preventing deformation during CNC milling was the key challenge for this project. To ensure consistently tight tolerance and reliable dimensions stability, two aluminum fixtures were milled to assist the low volume CNC milling, one for milling the outer surface and another for milling the side holes for buttons and USB.
Plaster powder was usually used instead of the custom fixtures to reduce prototype cost and time, this answered why tolerance of the low volume CNC parts was higher than the prototype one as well as the much shorter unit manufacturing time and lower unit price.
Packaged Parts for Shipping by Air Express. Before packaging the parts for shipping, every part went through the quality inspection in tolerance, shape stability and surface finishing, the substandard ones were sorted out for repair or remaking, the photos and quality inspection report were provided as per request.
