Paper Abstract

Parabolic cylindrical lens was polished with high efficient and precision using a flexible wheeled polished die by CNC polishing machine. A flexible wheel polished die was introduced. The CNC polishing machine has long travel , high speed and precision, so many parabolic lens can be cemented to form a bar for being polished. The effects of the tooling rotational velocity, amount of compression and curvature radius of the workpiece on the profile accuracy were investigated. In the short polishing period, the profile accuracy of the workpieces are less than 0.5 μm achieved by selecting optimum experimental parameters in the experiments. The polishing technology of high efficient and precision achieved by this precessing method is helpful to promote mass production of the parabolic cylindrical lens.
