Problems solved by technology

[0002] After the casting of the aluminum alloy rim blank of the automobile wheel hub is completed, it is necessary to cut off the parts left by the redundant gating system, such as the center riser, side riser, and gate. The existing method is to use a twist drill to pre-drill the center of the casting. holes, but the remaining material in the cutting blind area cannot be removed, and subsequent processing needs to be carried out in the CNC machine tool, which consumes a lot of time and low processing efficiency

Abstract

The invention relates to a drilling and milling cutter which comprises a blade I (1), a blade II (2), a blade III (3), a blade IV (4), a blade V (5), a blade VI (6), a cutter bar (7) and eleven socket head cap screws (10). A large boss (8) is arranged on the cutter bar (7), a small boss (9) is arranged under the large boss (8), the blade I (1) and the blade II (2) form a 180-degree angle respectively through the socket head cap screws (10) and are oppositely installed on the small boss (9), and the blade III (3), the blade IV (4), the blade V (5) and the blade VI (6) respectively form a 180-degee angle through the socket head cap screws (10) and oppositely installed on the large boss (8). The drilling and milling cutter is simple in structure, high in machining efficiency, low in cost, long in service life and used for machining aluminum alloy rims of automobile hubs.

Description

Technical field: [0001] The invention relates to a cutting tool, in particular to a drilling and milling cutter used for processing aluminum alloy wheels of automobile hubs. Background technique: [0002] After the casting of the aluminum alloy rim blank of the automobile hub is completed, it is necessary to cut off the parts left by the redundant gating system, such as the center riser, side riser, and gate. The existing method is to use a twist drill to pre-drill the center of the casting. hole, but the remaining material in the blind cutting area cannot be removed, and subsequent processing needs to be carried out in the CNC machine tool, which consumes a lot of time and low processing efficiency. Invention content: [0003] The object of the present invention is to provide a drilling and milling cutter with simple structure, high processing efficiency, low cost and long service life. [0004] In order to achieve the above object, a kind of drilling and milling cutter ...
