Abstract

The polishing machine suitable for polishing great size spherical diamond consists of upper cavity, lower cavity, locating compression rod mechanism, upper shaft magnetic fluid sealing mechanism, lower shaft magnetic fluid sealing mechanism, molybdenum support, lower grinding body and heater. The locating compression rod mechanism and the upper shaft magnetic fluid sealing mechanism are installed on the upper cavity, the lower shaft magnetic fluid sealing mechanism is installed on the lower cavity, the molybdenum support is installed on one end of the lower shaft magnetic fluid sealing mechanism, the lower grinding body is installed inside the molybdenum support, and the heater is installed inside the lower cavity. The present invention has simple design, simple installation and debugging, can realize curved polishing with only two rotating mechanisms, and may be used in processing optical level diamond.

Description

technical field [0001] The invention relates to a mechanical structure of a polishing machine, more specifically, a high-precision polishing machine that realizes contact polishing with a large-size spherical diamond through the rotation of a lower grinding body and a grinding ball head. Background technique [0002] With the development of diamond preparation technology, the cost of self-supporting thick-film artificial diamond is gradually reduced, coupled with the excellent physical properties of diamond itself, making its application in the optical field more and more prominent, becoming the first choice for optical imaging equipment in various harsh environments . However, after the preparation of artificial diamond, the surface finish is very poor, and its roughness value generally ranges from several microns to tens of microns, which seriously affects its optical properties. Therefore, as a high-precision optical grade product, it is necessary to polish the diamond s...
