Ultra-precision machining

>Core technology

Global advanced 5+
Axis single point diamond ultra-precision machining technology and the R&D technology for the machining equipment.
Breaking through the limitation of traditional 5-axis machining, the original sixth axis is developed to fabricate Fresnel lenses on the roller mold. It replaces the traditional technology for embossing planar Fresnel lenses, and greatly improves the machining accuracy and efficiency. The profile error can be less than 100 nm and surface roughness less than 2 nm.

5+ axis ultra-precision machining technology can be widely utilized in the future to fabricate the microstructure on the macro surface, so as to develop a new process route.

Multi-energy fields assisted machining technology

The technology by utilizing three energy fields, ultrasonic vibration, laser field and oxygen-rich field solves the problem that the traditional diamond tool can not fabricate super-hard carbon steel and similar materials. Meanwhile, it can effectively reduce the wear of diamond tool and greatly improve tool life and machining efficiency.

Machining and compensation integrated CAM system

The CAM software independently developed by Leading Optics can replace foreign CAM software and has original algorithms in 3-Dimensional freeform surface machining and compensation. It realizes the closed-loop and automation from machining to quality monitoring, which can greatly improve the compensation accuracy, reduce the time of program generation to improve work efficiency.
