Extrusion honing, also known as abrasive flow machining, is a new process developed in the 1970s. It is of great significance in extending the service life of molds, improving product quality, improving labor conditions, saving working hours, and improving economic benefits.
The workpiece is installed on the fixture and clamped by the upper and lower abrasive chambers. The upper and lower abrasive chambers are filled with a dry elastic grinding medium filled with abrasive.
Under the action of external forces, the piston is hydraulically operated to force the viscoelastic abrasive to pass back and forth through the machined surface of the workpiece, producing a polishing effect on it. The finely ground chips and burrs are contained in the fluid abrasive medium and taken away, thereby achieving surface polishing ｏｒ rounding, deburring, etc.
