The effect of progress in surface finishing of optical components on the collimated-beam properties of soft x-ray beamlines at synchrotron radiation facilities is demonstrated: a stripe pattern, experimentally observed in the 2D intensity profile of beamlines with optical components manufactured 10-15 years ago, would be strongly attenuated if the existing refocusing mirror was replaced by an u...

In this paper, a finishing system with a mounted abrasive tool is proposed for finishing of metallic molds. The shape of the mounted abrasive tool is a ball-end type. When a metallic mold with curved surface is polished, the orientation of the mounted abrasive tool is not only fixed but also its revolution is locked. The motion of the mounted abrasive tool is feedforwardly controlled based on a...

This paper discusses the experimental investigation to find out the optimal electrolyte composition in improving the surface quality of the gear teeth profile during surfacing finishing of bevel gears by the electrochemical honing process. In this study, AISI 1040 was used as the workpiece material, mixtures of sodium chloride and sodium nitrate in different ratios were used as the input parame...

Electrochemical buffing technology (ECB) applies electrochemical and mechanical finishing characteristics in the surface finishing process. ECB can buff ultrahigh purity components to make them shine, without leaving residual stress, micro-cracks, and etc. The control parameters of the ECB process include current density, the rate of revolution of the buffing head, the buffing pressure on the s...

We present a detailed investigation of the surface characteristics of five commercial titanium implants with different surface finishing (double acid etching, anodization and incorporation of Ca/P, acid etching and deposition of Ca/P, hydroxyapatite-blasting, acid etching and Ca/P-blasting) produced by five different manufacturers. A set of experimental techniques were employed to study the sur...
