Alloy strip cutting method, magnetic core machining method and magnetic core machining system

The invention provides an alloy strip cutting method, a magnetic core machining method and a magnetic core machining system. The invention relates to the technical field of winding magnetic core processing. The application of the cutting method comprises the following steps that the alloy strip is placed between the cutter body and the cutting groove, and the cutter body is driven to be connected into the cutting groove so as to cut the alloy strip; the alloy strip is divided into a first material section located on one side outside the cutting groove, a second material section located on the other side outside the cutting groove and a third material section falling into the cutting groove under the cutting pressure of the joint of the cutter body and the cutting groove. In the cutting treatment process of the alloy strip, the cutting position of the first material section of the alloy strip is subjected to cutting pressure which faces the interior of the cutting groove and is concentrated towards the center,
