Abstract

The invention relates to the technical field of drilling tools, in particular to a rolling supporting type deep hole drill which at least comprises a tool body, wherein blades in different forms are arranged at the front end of the tool body and include an inner blade, a middle blade and an outer blade, and at least two guide supporting parts are arranged on the outer wall of the tool body. Each guide supporting part at least comprises a pin roller and a pin roller containing cavity containing the pin roller. According to the rolling type guide supporting part in the embodiment, on the basis that only a guide supporting function is achieved in the prior art, heating is reduced through rolling friction, the heat dissipation difficulty of deep hole machining is lowered, rolling machining is conducted on the hole wall through rolling type auxiliary cutting, so that the surface quality of the hole wall is improved, and compared with the prior art,leap-type progress is achieved, and the rolling supporting type deep hole drill is in particular important to deep hole drilling machining.

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...
