Abstract

The invention is applicable to the technical field of polishing processing of high-precision optical elements, and provides a manufacturing device and manufacturing method of an asphalt polishing pad. Asphalt molten after being heated is shaped through a positioning and pressing structure of the manufacturing device. Meanwhile, according to the pressing method, aluminum foil is laid in a heating groove before pressing, asphalt is prevented from making direct contact with the heating groove, and the pressed asphalt polishing pad is level in surface and uniform in thickness; and the asphalt polishing pad with the shape matched with the shape of a flexible layer of a polishing disc can be prefabricated, and demolding is facilitated. The smooth and level surface obtained after pressing is more suitable for processing of optical lenses.

Description

technical field [0001] The invention belongs to the technical field of polishing processing of high-precision optical elements, and in particular relates to a manufacturing device and a manufacturing method of an asphalt polishing pad. Background technique [0002] In the field of optical processing, with the increasing requirements for lens precision, the wide application of aspheric surfaces and the maturity of small grinding head polishing technology, the requirements for asphalt smoothing technology also increase. In order to better fit the surface shape of the polishing disc during processing, a polishing disc with a flexible layer added between the rigid disc and the asphalt has appeared. In the traditional way, the asphalt is melted and poured directly on the polishing disc. If it is a metal rigid disc, the asphalt layer is easy to clean after use. However, the asphalt is poured directly on the flexible layer and cannot be cleaned, causing the entire flexible layer t...
