Manually grinding a lens ATM, Optics and DIY Forum

2020-3-27  Page 1 of 2 Manually grinding a lens posted in ATM, Optics and DIY Forum: Hello, I’ll start to grind a lens with a photographer friend who wanted after years of photography to make one himself to get a feel of the process. The first one will be made in a schott mirror blank, 102mm/15mm thick, and will be plano-convex. We don’t expect it to give diffraction limited pictures since the

OSA Online monitoring of a belt grinding process by

Industrially ground surfaces often have a characteristic surface topography known as chatter marks. The surface finishing is mainly monitored by optical measurement techniques. In this work, the monitoring of an industrial belt grinding process with a light scattering sensor is presented. Although this technique is primarily applied for parametric surface roughness analysis, here it is shown

Profile error compensation in precision grinding of

A high efficiency precision truing experiment for arc-shaped diamond grinding wheel is carried out on ultra-precision grinder NAS520X-CNC, the experimental setup is shown in Fig. 10.The parameters of the dressing experiments are shown in Table 2.In order to improve the truing efficiency, a 180# GC wheel was chosen to dress the120# diamond grinding wheel during the dressing experiment.
