Abstract. This paper presents results of glass capillary end face grinding and polishing by approach that reduces the edge chipping. Brittle materials have natural tendency for edge chipping what leads to beveling the sharp edges. Not beveled sharp edges on glass capillary are important for special applications like surface tension measurement of small liquid samples. We use common grinding and polishing process for capillary end face machining modified with gradual decreasing of grinding load based on the relation of the critical chipping load. Achieved surface roughness is measured using atomic force microscopy (AFM). Capillary inner edge quality is checked both with optical microscopes and electron microscope too. We achieved a non-chipped capillary inner edge with radius down to 100 nm.

The surfaces of the microlenses at the conical end-faces of optical fibers require high quality to keep the best performance of laser beam delivery. The polishing parameters play an important role to get the best quality of the microlenses. Most of the past researches study on the polishing parameters of flat surfaces. In this study, the polishing area of the conical end-face of the optical fiber is varied during fabrication. The relation between removed volume and removed thickness is built to determine the material removal rate. An experiment is carried out and the results show that the first two spinning turns are much effective for polishing under the parameters of the experiment.

In order to obtain the effects of the kinematical state on the profile precision of the fiber-optic end-face in the process of lapping and polishing, a kinematical equation of the lap-polisher with planet movement is developed. Based on these equations and the tribological model of CMP, the dimensionless distribution of the material removal volume (DDMRV) and the trajectories of abrasive grains cutting on the lap-polisher are numerically simulated with the way of stochastic abrasive grains. Then, the effects of the parameters of the lap-polisher on the uniformity of the DDMRV and the trajectory on the optical fiber end surface are discussed, and the results are that the DDMRV and the trajectory of abrasive grains have a rather better value when the length L of the planet carrier and the rotational speed n 1 of the ring gear are increased and the rotation speed n H of the planet carrier is chosen in an advisable parameter region.
