[0001] The invention relates to the technical field of roller cutters, in particular to an anti-sticking roller cutter. Background Art

[0002] Cylindrical milling cutters, also known as flat milling roller cutters, are used to process flat surfaces on horizontal milling machines. The teeth are distributed on the circumference of the milling cutter and are divided into straight teeth and spiral teeth according to the tooth shape. They are divided into coarse teeth and fine teeth according to the number of teeth.
