Single-sphere double-R watch cover secondary material reworking process and polishing device

Abstract

The invention discloses a single-sphere double-R watch cover secondary material reworking process and a polishing device. The single-sphere double-R watch cover secondary material reworking process comprises the steps that a watch cover to be polished is placed in a cavity structure of the polishing device to enable the spherical face of the watch cover to be in fit with the inner wall of the cavity structure; a fastener is adjusted to enable the watch cover to be clamped and fixed in the cavity structure; a grinding cover is arranged on the watch cover, and the side, with grinding skin, of the grinding cover is in fit with the plane side of the watch cover; a pressure rod ejector pin is controlled to be aligned with an ejector pin hole in the grinding cover, polishing liquid is injected,and the grinding cover is rotated under the drive of the pressure rod ejector pin so as to polish the plane side of the watch cover. In this way, the grinding cover only polishes the plane which needsreworking polishing of the watch cover rather than polishing the two faces of the watch cover, and defects of a traditional upper-sweeping lower-polishing way are avoided.

Description

technical field [0001] The invention relates to the field of polishing, more specifically, to a single-ball double-R watch cover material rework process and a polishing device. Background technique [0002] Polishing is a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and flat surface. It is a modification of the surface of the workpiece using polishing tools and abrasive particles or other polishing media. [0003] Take the watch cover with single ball and double R as an example, where the single ball means that the back of the watch cover is flat and the front is spherical, and the double R means that the front of the watch cover is formed with two R arcs. At the present stage, when the above-mentioned watch cover is reworked and polished with two materials, the processing method of sweeping up and down grinding is usually adopted, that is, both sides of the watch cover are pol...

Problems solved by technology

However, the method of sweeping up and grinding down has the following disadvantages for single-ball double R watch covers: First, the polishing method of sweeping up and down grinding will polish both sides of the product, causing scratches of different depths on both sides, making it difficult to achieve polishing Secondly, the thickness of the removed product is not well controlled by the method of sweeping up and down, and it is difficult to precisely polish the flat side of the watch cover.
