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 abr

Abstract

The invention discloses an auxiliary metal machining process for CuCr contact surface treatment machining. The process comprises the steps of magnetic grinding, abrasive matching, CuCr contact basketing, grinding and vacuum degreasing treatment; and number 10 industrial white oil is adopted as a grinding cooling wetting medium, mixed abrasive adopting a stainless steel needle is adopted as grinding polishing abrasive, a CuCr contact is subjected to magnetic grinding polishing, then vacuum degreasing, vacuum drying and vacuum packaging are conducted, and the technical requirement that "the surface of the CuCr contact is free of scratches, oxidation, stains and other defects" is met. The process is low in consumption, environment friendly and efficient, the oxidation risk of the polishing link is effectively avoided, the CuCr contact produced through the process is excellent in appearance quality, the surface appearance of the product is in inherent metallic luster, and the appearance consistency is high.

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...
