A high-precision grinding system for optical lenses utilises various HIWIN components to carry out demanding motion tasks. The machine, which has been specially developed for machining lenses up to 150 mm in diameter, enables the highest levels of accuracy in shaping and surface finishing.
The manufactured optical components are used, amongst other things, in optical and optoelectronic systems, for example in sensor, image processing, thermal imaging and night-vision applications in industrial and safety-critical ranges.
The linear motion axes of the 3-axis system are based on HIWIN linear guides, ballscrews with customised end machining and matching bearing units. This combination ensures precise, stable and repeatable positioning of all axes. The system is supplemented by a rotary axis featuring a DATORKER® strain wave gear and a servo drive. In conjunction with a diamond tool, this enables highly accurate rotational movement of the workpiece and thus the ultra-precise machining of optical components. Thanks to the high precision of the components used, the system achieves a thickness accuracy of ±0.01 mm and a radius of curvature accuracy of up to 1 μm. The high rigidity of the entire system also ensures a stable machining process and consistently high repeatability.
