Abstract

The invention relates to the technical field of drilling tools, and specifically discloses a rolling support type deep hole drill, which at least includes a cutter body, and the front end of the cutter body is provided with different types of blades, which are respectively an inner blade, a middle blade and an outer blade. A blade, the outer wall of the blade body is provided with at least two guide support parts, the guide support parts at least include a roller and a roller accommodating cavity for accommodating the roller. On the basis that the rolling guide support part in this embodiment only has the function of guide support in the prior art, it not only reduces heat generation through rolling friction, and reduces the difficulty of heat dissipation in deep hole machining, but also assists cutting through rolling type. The hole wall is rolled to improve the surface quality of the hole wall. Compared with the prior art, a leap-forward progress is achieved, which is of particular significance for deep hole drilling.

Description

technical field [0001] The invention relates to the technical field of drilling tools, in particular to a rolling support type deep hole drill. Background technique [0002] Deep hole drills are drills specially used for processing deep holes. In the process of processing deep holes, it is usually necessary to solve the problems of heat dissipation and chip removal. [0003] A BTA deep hole drill in the prior art has an integral cutter body, and the cutter body is provided with cutting inserts of different shapes, which are respectively an outer blade, a middle blade and an inner blade. Two support guide blocks in the form of arcs. [0004] In the BTA deep hole drill with the above structure, the support and guide block is fixed. During the drilling process, the support and guide block directly acts on the hole wall and has friction with the hole wall. Difficulty in cooling. SUMMARY OF THE INVENTION [0005] The technical problem to be solved by the present invention is...
