Problems solved by technology

[0003] In the existing process of through-hole processing, it is often to use the drill bit to directly drill chips after punching out the positioning hole with the sample punch, which will cause great damage to the drill bit; and when reaming and reaming the through hole, it needs to be replaced. A variety of different types of cutting tools make the processing process more cumbersome, which is not conducive to rapid processing

Embodiment Construction

[0025] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0026] Such as Figure 1-4 Shown, a kind of round hole processing method of the present invention, this method comprises the following steps:

[0027] S1, use the laser to drill holes on the workpiece where holes need to be drilled to form laser holes;

[0028] S2, using the drill bit of the drilling machine to expand the hole along the laser hole in S1;

[0029] S3, using a multi-head reamer to ream the through hole in S2;

[0030] After S4 and S3 are completed, the workpiece is transported to the next process;

[0031] The multi-head reamer that adopts in this method comprises the first cutter head 1 that carries out cylindrical hole preprocessing, the second cutter head 2 that described first cutter head 1 is further processed, the 3rd cutte...

Abstract

The invention relates to the field of cutters, in particular to a circular hole processing method. The method comprises the following steps that S1, places needing to be drilled on a workpiece are drilled by a laser to form laser holes; S2, hole expanding is carried out by a drill bit of a drilling machine along the laser holes of the step S1; S3, through holes of the step S2 are subjected to holeexpanding by a multi-head reamer; and S4, after the step S3 is completed, the workpiece is conveyed to the next working procedure. Firstly, positions needing to be drilled of the workpiece are machined to form a through hole by the laser, then drilling is carried out by the drill bit, axial force on the drill bit can be reduced to avoid the damage of the drill bit, and during the hole expanding of the through holes, rapid machining is realized by the multi-head reamer, so that the tedious process of clamping the cutters frequently is avoided, and the machining efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of cutting tools, in particular to a method for machining round holes. Background technique [0002] A reamer is a rotating tool with one or more teeth used to remove a thin layer of metal from the surface of a machined hole, and a reamer is a rotating finishing tool with a straight or helical edge used for reaming or repairing holes. Due to the small amount of cutting, the machining precision of the reamer is usually higher than that of the drill bit, and it can be operated manually or installed on a drilling machine. The reamer is used to ream the hole that has been drilled (or reamed) on the workpiece, mainly to improve the machining accuracy of the hole and reduce the roughness of its surface. It is a tool for finishing and semi-finishing the hole. . [0003] In the existing process of through-hole processing, it is often to use the drill bit to directly drill chips after punching out the positioning hole with t...
