Abstract

The invention relates to a grinding tool for a protective lens. The grinding tool comprises a drilling portion, a first sand isolation segment, a fine trimming face grinding segment, a rough ore facegrinding segment and a main driving shaft. The drilling portion, the first sand isolation segment, the fine trimming face grinding segment, the rough ore face grinding segment and the main driving shaft are sequentially connected and coaxially arranged. The fine trimming face grinding segment and the rough ore face grinding segment are each columnar. The outer diameter of the fine trimming face grinding segment is less than that of the rough ore face grinding segment. By means of the grinding tool for the protective lens, when rough grinding machining is conducted on the inner side wall of a through hole in the rough ore face grinding segment, the fine trimming face grinding segment cannot be subjected to large machining stress, and therefore, the rupture or deformation phenomenon of the fine trimming face grinding segment can be avoided; thus, the service life of the grinding tool for the protective lens can be prolonged, and cost can be lowered; in addition, the tool replacement frequency can be reduced in the production process, and the problem that product quality is lowered due to tool replacement is avoided; and production efficiency is improved.

Description

technical field [0001] The invention relates to a grinding tool, in particular to a grinding tool for protecting lenses. Background technique [0002] A traditional grinding tool for protecting a lens includes a drill bit connected in sequence, a rough ore surface grinding section and a finishing surface grinding section, and a main shaft for being connected to a torque output shaft of a driving motor. The operation steps of processing a through hole on the protective lens are as follows: first drill a through hole on the protective lens with a drill bit, then use the coarse ore surface grinding section to roughly grind the inner wall of the through hole, and then use the finishing surface grinding section The through hole can be made in the protective lens by fine grinding the inner wall of the through hole. However, during the rough grinding process of the inner wall of the through hole, fracture or deformation is likely to occur at the grinding section of the finishing s...
