3D Scanning on Large TBM Cutting Head

3D Scanning on Large TBM Cutting Head

A tunnel boring machine (TBM) is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. It can be applied to coal mining roadway excavation, tunnel construction of railway, highway and water conservancy projects, etc.

What does customer need?

Cutting head is an irreplaceable component for TBM and contributes a lot to crush rocks. But due to this, the cutting head is badly abraded, it is necessary to analyze machine abrasion. However, how to get accurate 3D data of the cutting head and conduct abrasion inspection?

Traditional Measurement

The cutting head of TBM is very large and complicated in design. The surface is covered with the tooth holder, pick and spiral blade. Therefore, it will take the traditional vernier caliper too much work time, and the measuring accuracy can’t be guaranteed.

ScanTech 3D solution

ScanTech developed a global initiative 3D scanner called PRINCE, which combined red and blue laser technologies. The two working modes could rapidly switch according to speed and detail requirement, and integrate data file of abrasion inspection.

ScanTech PRINCE 3D laser scanner integrates the advantages of normal handheld 3D scanners in efficiency and accuracy. It can detect large plane even small coin, so the huge TBM cutting head can be easily and quickly detected. PRINCE 3D scanner delivers precise 3D data for machinery manufacturing to decrease abrasion, original data back-up and optimize product design.
