摘要

PROBLEM TO BE SOLVED: To provide a cutter table and a cutter blade for chamfering, and a chamfering machine in which a cutter tip is easily fixed to the cutter table and looseness of fixation of the cutter tip is inhibited during work.SOLUTION: Fixing seats 25 for internally housing cutter tips 10R are recessed in wall surfaces 24 of a plurality of chip pockets 23 disposed on a cutter table 20. Each fixing seat 25 has a threaded hole 26 in a flat bottom surface 25A for screwing to tighten and fix the cutter tip 10R, and a lateral peripheral surface 25B erected from the circumference of the flat bottom surface 25A is formed in a concavoconvex shape corresponding to a shape of a circumferential surface 13 of the cutter tip 10R by disposing a plurality of projecting parts 27. At least two surfaces of the circumferential surfaces 13 of the cutter tip 10R housed in the fixing seat 25 come into face contact with the lateral peripheral surfaces 25B of the fixing seat 25 formed into the concavoconvex shape.
