Embodiment Construction
[0037] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many ways other than those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the basic implementation disclosed below.
[0038] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other e...

Abstract
The invention belongs to the technical field of cutting, and particularly relates to a cutter chip breaking structure and a cutting tool with the same. The cutter chip breaking structure is arranged on a corresponding cutting component, the cutting component is provided with a front cutter face, a rear cutter face and a cutting edge located at the intersecting line of the front cutter face and the rear cutter face, and the cutter chip breaking structure comprises a first chip breaking face. The first chip breaking face is provided with a first side edge intersecting with the front cutter face, the first chip breaking face is bent in the direction away from a plane where the front cutter face is located, all points on a bent track line of the first chip breaking face are located on the same side of the plane where the front cutter face is located, the circle center of the bent track is located outside the cutting component, during chip breaking, The cutting edge enables cuttings to generate basic deformation, then the cuttings reach a first cutting face through the front cutter face and are subjected to secondary deformation along the bend track of the first cutting face to achieve further hardening and embrittlement till a cutter breaks off the cuttings, semi-finish machining can be converted into finish machining, and different cutting depths and feeding requirements are met.
Description
technical field [0001] The invention belongs to the field of cutting technology, and in particular relates to a cutting tool chip breaking structure and a cutting tool with the same. Background technique [0002] In the cutting process, the flying chips will reduce the safety of the working environment, and the long chips will be entangled on the workpiece or the cutter head, which is easy to scratch the workpiece and damage the tool. For automatic processing machine tools, each The work of the cutting tool is interlocking. If a cutting tool is not reliable in chip breaking, it will affect the entire machining process. It can be seen that when designing the cutting tool, the reliability of chip breaking must be considered. [0003] When designing the tool, the width of the chip flute should also be appropriate to the depth of cut. Otherwise, when the flute is too narrow, the chip will appear wide and not easy to curl in the flute. Often the chips do not flow through the bott...
