Introduction:
Despite the intelligence and precision of machines, human oversight remains irreplaceable.
BLT-AutoCAL, a multi-galvanometer automatic calibration product from BLT, automates the calibration process, integrates calibration and splicing, and simplifies parameter configuration and visualization. The operation is simple yet highly efficient and precise.
Why Automation?
One might question the need for automatic calibration since manual calibration can achieve precision. The answer lies in efficiency. Over time, the precision of galvanometer motors is prone to deviations, and maintaining high precision is a costly and low-efficiency task. Instead of having skilled technicians focus on this repetitive task, BLT developed AutoCAL to handle these corrections, allowing technicians to prioritize higher-value tasks.
Due to the stringent quality requirements in aerospace and medical fields, large-scale, multi-laser, high-efficiency, and modular production is becoming industrialized. Enhancing galvanometer calibration efficiency and accuracy can improve part quality and production efficiency. As the key to precise laser scanning in metal 3D printing, the galvanometer’s precision directly affects part quality. Thus, BLT-AutoCAL is essential for mass production.
Innovation through Automation
BLT developed AutoCAL to address galvanometer calibration issues in metal additive manufacturing. Drawing on over a decade of experience using hundreds of PBF-LB/M machines, It developed AutoCAL, which is tailored to meet specific production conditions and can offer more customized services.
Unlike traditional semi-automatic methods, BLT-AutoCAL uses photosensitive sensors and BLT’s proprietary alignment correction controller (ACC), reducing calibration errors to less than 0.03mm and improving precision by 40%. Furthermore, the calibration time is significantly reduced; Taking BLT-S400 as an example, the calibration time for a six-laser equipment drops to 70 minutes, a 23% increase in efficiency. For a three-laser equipment, it is reduced to 40 minutes, a 33% improvement in efficiency.
BLT-AutoCAL supports high customization for fields like aerospace, medical, and shoe mold, meeting high-precision demands. It also supports personalized algorithm adjustments and can be integrated with BLT-MCS, thus reducing learning cost and ensuring high-precision and high-quality calibration.
BLT-AutoCAL offers multiple calibration strategies, meeting diverse customer needs.
With its upgraded UI, featuring a clean layout and user-friendly operation, it also visualizes the calibration process. BLT-AutoCAL strives for user acknowledgement in the pursuit of excellence.
Currently, it supports several BLT equipments, including BLT-A160, BLT-A300/A320, BLT-S210, BLT-S310/S320, and BLT-S400, with unlimited number of lasers that can be matched within its supported dimension. BLT engineers will continue R&D for further optimization of BLT-AutoCAL, enabling larger dimension and more efficient galvanometer calibration across all its equipment models. As BLT continues to advance, we stand ready to forge ahead with you, striving for excellence through craftsmanship.
