The invention relates to the technical field of machining tools, in particular to a machine clamp type annular cutting tool. The machine clamp type annular cutting tool comprises a handle portion anda cutting edge portion, wherein a guide supporting strip is arranged between every two adjacent cutting edges of a cutting portion, the outer surfaces of the guide supporting strips are arc surfaces coaxial with the cutting portion, and the diameter of the outer surfaces of the guide supporting strips is smaller than the maximum diameter of the points of the cutting edges. According to the structure of the machine clamp type annular cutting tool, in the hole machining process of the cutting edges, the axis of the cutting portion is deviated from a rotary center due to the radial component force of the cutting edges, then the outer surfaces of the guide supporting strips can be in contact with the inner surface of a machined hole so as to neutralize the radial component force generated by the cutting edges and to correct the deviation of the cutting portion, then the radial shake of the toll during cutting is controlled within the precision range, damage of hole machining equipment is avoided, and the cutting tool can also be suitable for machining deep annular holes.
Description
technical field [0001] The invention relates to the technical field of machining tools, in particular to a machine clip-type annular cutting tool. Background technique [0002] Annular cutting tools in the prior art, such as the blade removable steel drill disclosed in CN106180828A, the screw axial clamping replaceable blade steel drill disclosed in CN203018803U, etc., all overcome the cutting unbalanced force of the cutting edge through the rigidity of the equipment. The disadvantage of such a structure is that the precision of the processed hole and the surface quality of the hole are poor, which will cause damage to the processing equipment. The most important thing is that only shallow holes can be processed, and deep holes cannot be processed stably. Contents of the invention [0003] The technical problem to be solved by the present invention is to solve the defect that the annular cutting tool in the prior art relies on the rigidity of the equipment itself to overco...
