The main shaft of the compressor rotor has a relatively large volume, 1.8m in length, 0.96m in diameter, and with a weight of about 300kg. Therefore, the scanning area and speed of the 3D scanner are required to be wide and fast, which can directly affect work efficiency.
There are multiple impellers distributed on the main shaft of the rotor. The distance between the impellers is narrow, and the impellers have deep flow channels and many curved surfaces, so it requires the 3D scanner to have a larger depth of field and high accuracy. It is difficult for ordinary 3D scanners to achieve this comprehensive scanning.
The main shaft of the rotor is made of steel, with a shiny machined surface, so the scanner is required to work normally under reflective conditions.
ScanTech 3D solution
Our AXE 3D scanner is customized for 3D detection of medium to large-sized objects. For traditional 3D scanners, they need to work with a photogrammetry system device to finish the detection. However, with a built-in photogrammetric system, AXE can quickly obtain 3D data of large workpieces, realizing the whole 3D scanning only by itself, greatly reducing the cost of detection.
AXE 3D scanner adopts advanced optical measurement technology, achieving the maximum scanning area 860 mm × 600 mm, and the measurement speed 2,000,000 measurements/s. Even if the workpiece is exceptionally large, it can also complete the detection efficiently and promptly.
For the narrow space between the impellers and inaccessible positions, we can choose deep hole scanning work mode, with a depth of field of 500 mm, resolution of 0.025 mm, and an accuracy of 0.020 mm, which can accurately capture the 3D data of complex and shiny surface.
Step 1. Photogrammetry system
By using photogrammetry system, it can obtain more accurate data of positioning markers and determine the 3D coordinates of the object in space, such as the position, shape, and size, so as to obtain the scan data with better precision.
Step 2. 3D scanning
According to the scanning requirement, we can switch the working mode to high-speed scanning or deep hole scanning, to accurately inspect key positions, realizing the non-contact measurement and simple operation.
Step 3. STL data collection
Import the scanned data into professional 3D software ScanViewer for post-processing and obtain a 3D model for later maintenance. The entire data scanning and processing can be completed within half an hour.
AXE 3D scanner greatly optimizes the workflows when inspecting large-scale workpieces, ensuring the products’ work efficiency and life cycle.
Meanwhile, ScanTech’s KSCAN composite 3D scanner adopts a built-in photogrammetry system and opens up the first introduction of infrared laser technology, which makes large-scale project measurements much easier.
