Problems solved by technology

Dry polishing cannot completely avoid the risk of cleaning
[0004] In addition, the general wet polishing mostly uses water or water-based medium as cooling and wetting, which greatly increases the risk of product oxidation, and subsequent cleaning cannot ensure that the surface of the product is clean, and there are often water stains. Improper cleaning of ceramic abrasive polishing products will leave a small amount of residual powder residue
According to statistics, as a contact manufacturer with an annual output of 8 million PCS, the annual number of product repairs caused by oxidation and other appearance problems in the manufacturing process accounts for as much as 10%, and the cost for this part of the repair is also very high

Abstract

The invention discloses an auxiliary metal processing technology for CuCr contact surface treatment, including magnetic grinding, abrasive ratio, CuCr contact basket loading, grinding, and vacuum degreasing treatment; No. 10 industrial white oil is used as the grinding, cooling and wetting medium , using mixed abrasives with stainless steel needles as grinding and polishing abrasives, magnetically grinding and polishing CuCr contacts, and then vacuum degreasing, vacuum drying and vacuum packaging to meet the requirements of "no scratches, oxidation and stains on the surface of CuCr contacts" technical requirements. This method is low in consumption, environmentally friendly, and efficient, and effectively avoids the risk of oxidation in the polishing process. The CuCr contacts produced by this method have excellent appearance quality, and the product surface has an inherent metallic luster and a high degree of appearance consistency.

Description

technical field [0001] The invention relates to the technical field of metal surface processing, in particular to an auxiliary metal processing technology for CuCr contact surface processing. Background technique [0002] One of the technical requirements for the delivery appearance of CuCr contacts for vacuum interrupters is "no surface defects such as scratches, oxidation and stains", which requires good appearance quality. Defects such as oxidation and scratches on the surface of the contact material will affect the functional characteristics of the vacuum interrupter, so these defects are not allowed. In the process of contact manufacturing, due to the long process and many process links, the product is frequently grasped and moved in sequence, and the total duration of the process is long. It is inevitable that different degrees of scratches, oxidation, etc. will occur on the final cutting surface. Surface appearance defects, it is difficult to achieve a high degree of...
