Abstract

The invention relates to an indexable drilling bore chamfer compound cutter. The indexable drilling bore chamfer compound tool comprises a cutter rod, an inner-blade blade and an outer-blade blade, wherein the cutter rod is located on the back portion of a shaft shoulder, the cutter rod is provided with a cutter handle connected with a cutter seat, the front portion is provided with an inner-blade chip groove and an outer-blade chip groove, the inner-blade blade is arranged on the front portion of the inner-blade chip groove, the outer-blade blade is arranged on the front portion of the outer-blade chip groove, the cutter rod is located on the middle upper portion of the inner-blade chip groove, and is provided with a cutter holder which is adjustable along an axial direction, a fine boring blade is adjustably arranged on the cutter holder in a radial direction, and the end face of the fine boring blade is lower than the groove bottom surface of the inner-blade chip groove. A chamfer blade is arranged on the front end face of the shaft shoulder of the cutter rod, a cooling water channel inside the cutter rod is respectively communicated with a fine boring blade water channel, an outer-blade blade water channel and an inner-blade blade water channel, and the front ends of the fine boring blade water channel, the outer-blade blade water channel and the inner-blade blade water channel are respectively arranged in the fine boring blade, the outer-blade blade, and the inner-blade blade. The indexable drilling bore chamfer compound cutter has the advantages of being rational and compact in structure, stable in machining quality, and further capable of improving machining efficiency.

Description

technical field [0001] The invention relates to an indexable drilling, boring and chamfering compound tool, which belongs to the technical field of compound tools. Background technique [0002] To process 8-level precision holes on steel parts with a hardness of about 30HRC, two processes of drilling and boring are usually used for processing, and finally chamfering is required at the hole. [0003] At present, for the intermediate machining of holes with 8-level precision, one is to drill and ream holes on a machining center or a drilling machine through an ordinary high-speed steel drill bit, and then use a boring tool to perform boring and chamfering. Although this kind of tool is cheap, the high-speed steel drill bit is not wear-resistant, has a short service life, consumes a lot of tools, and needs to change the tool frequently, so the processing cost is high and the processing efficiency is very low. The other is to use a shallow hole drilling compound tool. The end o...
