Abstract
The invention discloses an accurate grinding piece for surface rough polishing of an optical device. A honing oilstone comprises the following components in percentage by weight: 70-88% of copper powder, 10-20% of tin powder, 1-5% of silver powder, and 1-5% of diamond (a particle size range is W40-W5). The accurate grinding piece is prepared by performing the mixing and vacuum hot pressing process for the raw materials in proportion. The accurate grinding piece has the characteristic of synchronously satisfying such comprehensive machining requirements as size tolerance, roughness, machining efficiency and service life, solves such problems as low surface polishing efficiency and unstable polishing quality of a similar device, and is generally applied to matching of a production lien for machining optical and related parts.
Description
Technical field
The invention belongs to precision optics cold working field, be specifically related to a kind of precise abrasive plate for optical component surface rough polishing.
Background technology
Optics cold working mainly produces optical component, and the downstream industry for optical instrument, photoelectron image information processing product etc. provides the optical element such as eyeglass, camera lens.Optical instrument and the photoelectric digital products such as such as digital camera, shooting mobile phone, scanner, projector, back projection TV, DVD player, bar code reader.
Optics cold working is distinguished from material, has glass and the big class of plastic cement two.Glass lens is divided into plane mirror and the big class of lens two, and wherein plane mirror includes plate glass and prism, and lens then include coquille and aspheric surface.The cold worked main technique of optics have die mould, cutting, milling, refine, polish, edging, joint, plated film etc..
The top technology of whole world optics cold rnning industry mainly rests in Japan, the U.S. and manufacturer of Germany on hand, and wherein Japan has grasped the main source of global optics cold processing technique.Along with the great development of photoelectric technology modern since in recent years, optical technology developed country adjusts self industrial structure and industrial development direction one after another, is gradually backed out traditional optical manufacture field, concentrates to the manufacture of photovoltaic modern, high-end, research and development；TaiWan, China, China's Mainland are then increasingly becoming the cold worked manufacturing center of whole world optics.
The core technology of optics cold machining process is fine grinding and polishing, refines and polish use diamond precise abrasive plate.At present, the diamond precise abrasive plate that China produces is only used for the polishing of the highest glass of prescription, and high-end optics polishing still needs to use the diamond precise abrasive plate of import.Therefore, the diamond precise abrasive plate required for advanced optical device fabrication has yet-to-be developed.
Summary of the invention
It is an object of the invention to provide a kind of precise abrasive plate for optical component surface rough polishing, with the requirement of the efficient polishing of glass.The problems such as it is low that this product solves similar optical component surfaces polishing efficiency, and polished surface quality is unstable.
The preparation method of the honing stone of the present invention comprises the following steps:
The composition of honing stone and percentage by weight be: copper powder 70～88%, glass putty 10～20%, argentum powder 1～5%, diamond 1～5% (particle size range 100 mesh～300 mesh).
Its preparation technology is as follows:
A, metallic bond and diamond are carried out batch mixing by proportioning；
B, vacuum hotpressing, hot pressing temperature is 650～750 DEG C, and hot pressing time is 2～5 minutes, and pressing pressure is 2～4MPa, and vacuum is 1 × 10-3Pa。
