Machining technique of anchor chain Kenter shackle

The invention relates to a machining technique of an anchor chain Kenter shackle, which comprises the following steps: connecting a tooling with a working platform of a numerical control (NC) milling machine, and connecting a molding cutter with the main shaft of the NC milling machine, wherein the fixture is provided with four workpiece mounting positions. The NC milling machine enables the mainshaft to rotate to move the working platform, so that the molding cutter machines a workpiece according to the following steps: machining the surfaces A and B of each workpiece; machining the surfaces C and D of each workpiece; machining the surfaces E and F of each workpiece; and machining the surfaces G and H of each workpiece. The four workpieces are clamped and machined within one time, thereby ensuring uniform size of the workpieces; the invention reduces the number of clamping and the number of transportations by the workers, and greatly reduces the labor intensity; the eight machining surfaces of each workpiece
