Problems solved by technology

These two technologies use a diamond dressing pen as a scratching tool, and use a single pendulum structure to realize the scratching process, but the scratching line speed is 1.5m / s, which is still far lower than the grinding wheel line speed during grinding

Abstract

The invention relates to an optical glass scratching testing device which belongs to the technical field of material testing. The optical glass scratching testing device comprises a tray, a clamp and a scratching instrument, wherein the clamp is arranged on the tray; the scratching instrument is arranged opposite to the tray and the clamp; a feeler gauge is arranged between the bottom of the clamp and the tray; and the included angle between the clamp and the tray is adjustable. The invention can obtain different scratching speeds by adjusting the speed of mainshaft of the lathe, and obtain different scratching depths by adjusting the included angle between the clamp and the tray. The invention has the advantages of simple structure, convenient operation and high testing accuracy.

Description

technical field [0001] The invention relates to a device in the field of testing technology, in particular to an optical glass scratch test device with a scratch speed greater than 15m / s. Background technique [0002] Optical glass is an important inorganic non-metallic material with high transparency and physical and chemical uniformity. It is widely used in laser technology, optical communication, aerospace and defense industries and other fields. In order to process high-precision optical glass, it is usually necessary to perform ultra-precision grinding on optical glass. However, due to the high brittleness and low fracture toughness of optical glass, the processing efficiency of ultra-precision grinding is low, and the processing quality is difficult to guarantee. It has become a bottleneck link restricting the further development of the optical industry. Through the optical glass scratch test, analyzing the influence of scratch parameters on the material removal mecha...
