A special processing equipment for artificial crystal material bowl-shaped fairing

Abstract

The invention relates to a sphere machining device and method for a bowl-shaped fairing made of ultra-hard and ultra-brittle artificial crystal materials, in particular to a special machining device for bowl-shaped components made of ultra-hard and ultra-brittle materials such as special glass, artificial sapphire, magnesium fluoride, spinel, zinc sulfide and germanium single crystals. The machining device comprises an HT250 casting base, a workpiece shaft drive system, a workpiece flexible clamp, an X-direction linear guide way, an X-direction linear guide way sliding block, a Y-direction linear guide way installation transition board, a Y-direction linear guide rail, a Y-direction linear guide rail sliding block, a 360-degree dividing plate, a bowl-shaped milling and grinding wheel, a spindle head and a drive motor. The equipment investment in the early stage is low; the performance is stable and reliable; the degree of dependency on the personnel technical level is low; machining of the bowl-shaped fairing can be completed with high efficiency and high quality; the disadvantages that imported special sphere milling and grinding machines are expensive and a four-axis machine or a two-axis machine is low in machining efficiency are overcome thoroughly; bulk copying and production expansion are facilitated; the machining device has high technical value and economic value, and is helpful to improve the machining level of domestic bowl-shaped fairings or windows.

Description

technical field [0001] The invention relates to a processing equipment and method for a bowl-shaped fairing of artificial crystal material, which is specifically applied to bowls of superhard and superbrittle materials such as special glass, artificial sapphire, magnesium fluoride, spinel, zinc sulfide, germanium single crystal, etc. Special processing equipment for shaped parts. Background technique [0002] Since most IOL materials have material properties that cannot be turned, most of the original IOL bowl-shaped windows are processed by imported high-speed milling machines and traditional four-axis machines (or two-axis machines) with special tooling. Imported high-speed milling machines are seriously Restricted by the technology monopoly of international giants, the price is extremely expensive, such as: German Schneider, German Raul, British ZEEKO, German optotech and other special processing equipment, each of which is about 500,000 euros, with a set of special tools...

Problems solved by technology

[0002] Since most IOL materials have material properties that cannot be turned, most of the original IOL bowl-shaped windows are processed by imported high-speed milling machines and traditional four-axis machines (or two-axis machines) with special tooling. Imported high-speed milling machines are seriously Restricted by the technology monopoly of international giants, the price is extremely expensive, such as: German Schneider, German Raul, British ZEEKO, German optotech and other special processing equipment, each of which is about 500,000 euros, with a set of special tools and equipment The price is about 5 million RMB, which is very unfavorable for domestic enterprises, especially small and medium-sized enterprises to use in batches. The grinding efficiency of traditional four-axis machines or two-axis machines with special tooling is extremely low, and the product interchangeability is poor. In view of this, there is an urgent need to fill the gap in the market. A low-cost, high-efficiency and high-quality special processing equipment and method are urgently needed for the processing of blank artificial lens material bowl-shaped fairings or windows
