摘要： A reliable galvano-mirror employed for laser machining is disclosed. The mirror is far reduced its weight for getting a higher rotation. On the rear surface of the mirror, a lightweight rib-structure, which is formed from a mirror support beam centered across the surface and some ribs extending from the beam, holds the mirror. Against a distortion occurred in rotating at high speed, the mirror is provided with a high rigidity. And the mirror is structured integrally with the motor shaft holder. Besides, a slit is formed between the rib disposed close to the holder and the support beam centered across the rear surface of the mirror. Providing slit enables to minimize a local distortion caused by a stress from fastening screws to attach the mirror to the motor shaft.

摘要翻译：公开了一种用于激光加工的可靠的电流镜。镜子远远减少了重量，以获得更高的旋转度。在反射镜的后表面上，由反射镜支撑梁形成的轻巧的肋状结构，该反射镜支撑梁横跨该表面和从该光束延伸的一些肋保持该反射镜。为了在高速旋转时出现变形，镜子具有高刚性。镜子与电机轴架一体形成。此外，在靠近保持器设置的肋和跨过镜的后表面的支撑梁之间形成狭缝。提供狭缝使得能够最小化由来自紧固螺钉的应力引起的局部变形，以将反射镜附接到电动机轴。
