Problems solved by technology

[0002] In the field of mechanical processing, it is a difficult point to process the inner concave cylinder hole. The commonly used method is to use the expansion tool to process it on a special machine tool. The structure of the expansion tool is complex and the processing stability is poor, and it can be done on a special machine tool. Processing cannot be processed on flexible line CNC equipment, and flexible production cannot be realized. It is necessary to purchase special equipment and tools for processing, which increases the processing cost for the enterprise

Abstract

The invention discloses a cutter for machining an inner concave cylinder hole and a machining method of the cutter. The cutter for machining the inner concave cylinder hole comprises a cutter body, afirst-stage cutter, a second-stage cutter and a third-stage cutter, wherein the outer periphery of the cutter body is provided with an elliptical receding side, the cutter body sequentially forms a first step, a second step and a third step from the axial front end to the inside, and the first step is a tool bit; the first-stage cutter is arranged on the tool bit, so that the diameter of the toolbit after the first-stage cutter is installed is smaller than that of a front hole of the cylinder hole; the second-stage cutter is arranged on the second step and used for machining a cylinder hole chamfer; the third-stage cutter is installed in the third step and used for machining the concave cylinder hole. According to the cutter for machining the inner concave cylinder hole and the machiningmethod of the cutter, the concave cylinder hole is machined in a numerical control machine tool, the problem that the concave cylinder hole has to be machined by a special machine tool and a cutter issolved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of engines, in particular to a cutter for machining an inner concave cylinder hole and a machining method thereof. Background technique [0002] In the field of mechanical processing, it is a difficult point to process the inner concave cylinder hole. The commonly used method is to use the expansion tool to process it on a special machine tool. The structure of the expansion tool is complex and the processing stability is poor, and it can be done on a special machine tool. Processing cannot be processed on the CNC equipment of the flexible line, and flexible production cannot be realized. It is necessary to purchase special equipment and tools for processing, which increases the processing cost for the enterprise. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any fo...
