Abstract

The invention discloses a special saw blade for cutting an outer water retaining part and a bright strip of an automobile. The special saw blade comprises a round saw blade. The thickness of the roundsaw blade is 1.3-1.6 mm, noise reduction lines, the diameters of which are 0.2-0.5 mm, are arranged on the round saw blade, and saw blade tool bits are welded to the round saw blade by using a metalceramic. The thicknesses of the saw blade tool bits are 1.8-2.2 mm, the depths of the saw blade tool bits are 3.0-4.5 mm, the widths of the saw blade tool bits are 1.0-2.0 mm, the angles of the frontangles alpha of the saw blade tool bits are 7-18 degrees and the angles of the back angles beta of the saw blade tool bits are 10-15 degrees. The special saw blade disclosed by the invention reduces the cutting noise effectively, the service life of the saw blade is prolonged, a cutting section is smooth and free of burrs, and the service life of the saw blade is prolonged.

Description

technical field [0001] The invention belongs to the technical field of cutting tools for automobile parts, in particular to a special saw blade for cutting automobile outer water barriers and bright strips. Background technique [0002] The window light strip is an accessory installed on the surrounding edge of the car window for decoration and windshield.
