Case Study: HGG Profiling Equipment achieves 0.5 mm cutting accuracy with Hexagon Leica Absolute Tracker

Leica Absolute Tracker AT901 monitors cutting of wind turbine tripods

HGG Profiling Equipment, a Dutch manufacturer of steel profiling machinery, was challenged to precisely cut massive 60-meter-long, 400-ton steel tubes for wind turbine tripods. These tubes deformed significantly under their own weight, making traditional cutting methods inaccurate and risking the creation of extremely expensive scrap material. To solve this, HGG integrated a Hexagon Leica Absolute Tracker laser measurement system into their cutting machine.

Hexagon's solution involved continuously monitoring the position of both the cutting head and the deforming tube in real-time, with measurements taken every 100 milliseconds. This data allowed the machine to automatically compensate for any movement, ensuring a perfect cut. The result was the ability to cut these extremely large components to an accuracy of 0.5 mm, eliminating cutting errors and allowing their customer to perform the task with precision and reliability.
