The smooth hand feel starts from your palm. The surface glass extends down along the edges to form an elegant arc and precisely links with the Anodic Aluminum Oxide middle frame.
Inspired by principles of architecture and the intuitive design of the human skeleton, the nubia Z9 Max has a rock-solid frame designed to offer the best protection possible for the components inside.
In order to design a solid frame on nubia Z9 Max, we finally decided to adopt the aircraft-grade aluminum alloy materials with low density but high intensity. Meanwhile, it features excellent thermal conductivity and corrosion resistance.
The sophisticated process contains CNC carving procedure with a total of 90 specially-designed milling cutters.
|Customized carving tools||30+|
|Milling and Grinding||16000r/min|
In order to work out a method that best suits your palm, we have performed repeated experiments, investigations and researches on hundreds of hand-hold devices and found out the most comfortable arc for your palm on 5.5 inch smartphones.
Grinding the edges with the 205# Zircon sand grains, continuously spraying with 16 ejection guns for 720 seconds at 360° to work out the skin-like sensations.
|Diameter of 205# Zircon sand grains||0.065mm|
|Sand spraying and grinding gun||16|
Performing three anodic oxidation and coloring experiments, more than 100 tests on different colors just to work out the ceramic anti-abrasion surface.
In order to guarantee the holding feel and smooth feel of edges, firstly go through 22-points precise positioning, then perform one-time high-speed polishing machine using CNC to engrave with the diamond tip, and finally perform second oxidation to the 0.65mm chamfer to form a protection layer.
