The main function of the screw is to connect the two workpieces together for fastening. Screws are used in almost all machines. The screw itself is metal, which is easily corroded by acid and alkali or rust, which affects the performance and aesthetics of the screw. Therefore, the screws are often coated with a coating to prevent corrosion. The three-dimensional data of the surface of the screw is obtained with the aid of three-dimensional scanning technology to calculate the surface area of the screw.

Practical problems
The size of the screw is small, and the thread gap is also small. To complete high-precision scanning, the three-dimensional scanner used has high requirements and can accurately obtain the scanned data. If a fixed scanner is used, it is difficult to scan the thread gap, and it is impossible to capture the details inside. Therefore, the needs of customers cannot be fulfilled, and the new three-dimensional scanning technology is applied, which is high-precision and fast scanning to obtain data.

Solution
According to customer needs and workpiece conditions, Hualang technical engineers quickly gave a solution: use the HOLON751 handheld 3D scanner to scan the screw comprehensively and quickly to obtain high-precision data.
