BAND SAW BLADE FOR METAL Russian patent published in 2024 - IPC B23D61/12 

FIELD: metal cutting.

SUBSTANCE: invention relates to devices for metal cutting and can be used for mechanical processing of metals, composites, plastic and other hard materials. Saw blade comprises a saw edge with main cutting teeth and additional sections, the teeth of which have smaller height and pitch relative to the main cutting teeth of the saw edge or abrasive elements are made on the saw edge of these sections. Between the beginning of the row of the main cutting teeth and the teeth or abrasive elements of the additional sections, respectively, there are transition teeth or abrasive elements. Between the end of the row of the main cutting teeth and the teeth or abrasive elements of the additional sections there are gaps in size larger than the pitch of the main teeth.

EFFECT: service life of the metal band saw blade and its teeth is increased due to the reduction of blade vibration, deformation and blunting of the teeth.
