Terminology of Sheet Metal Processing Industry

Every industry has its professional terms, and the sheet metal processing industry is no exception. The following 25 are common.

(1) Pressure riveting: refers to the process of firmly crimping fasteners such as pressure riveting nuts, pressure riveting screws, or pressure riveting nut posts on the workpiece using a punch or hydraulic press.

(2) Expanding riveting: refers to the process of first countersinking the workpiece, and then using a punch or hydraulic press to firmly crimp the expanding rivet nut on the workpiece.

(3) Pull mother: refers to the use of similar riveting process. The process of firmly connecting connecting pieces such as pop rivet nuts (POP) to the workpiece with a female gun.

(4) Pull riveting: refers to the process of using a riveting gun as a tool to tightly connect two or more workpieces with pull nails.

(5) Riveting: the process of connecting two or more workpieces face-to-face with rivets. For countersunk riveting, the workpieces must be counter-bored first.

(6) Corner cutting: refers to the process of cutting off the corners of the workpiece using a die on a punch or hydraulic press.

(7) Bending: refers to the process of forming a workpiece by a bending machine.

(8) Forming: refers to the process of deforming the workpiece using a mold on an ordinary punch or other equipment.

(9) Cutting material: refers to the technological process of obtaining a rectangular workpiece through a shearing machine.

(10) Blanking: refers to the technological process of the workpiece being cut by LASER or punched by CNC punch.

(11) Blanking: refers to the process of using molds to obtain product shapes on ordinary punches or other equipment.

(12) Punching: refers to the technological process in which the workpiece is processed by ordinary punches and molds.

(13) Punching convex hull: refers to the process of forming a convex shape of a workpiece with a die on a punch or hydraulic press.

(14) Punching and tearing: also called "punching bridge", it refers to the process of forming a workpiece into a bridge-like shape in a punch or hydraulic press with a mold.

(15) Hole extraction: also called "flanging", which refers to the process of forming a round hole on a workpiece using a mold on an ordinary punch or other equipment. process.

(16) Tapping: refers to the process of machining internal threads on the workpiece.

(17) Leveling: refers to the process of using other equipment to level the workpiece before and after the workpiece is uneven.

(18) Thread retraction: refers to the process of the second thread restoration of a workpiece that has been tapped in advance.

(19) Drilling: refers to the technological process of drilling a workpiece with a drill bit on a drilling machine or milling machine.

(20) Chamfering: refers to the process of processing the sharp corners of the workpiece using molds, files, and grinders.

(21) Stamping: refers to the process of stamping out characters, symbols or other imprints on the workpiece using a mold.

(22) Counterbore: Refers to the process of processing taper holes on the workpiece to match the connecting parts like countersunk screws.

(23) Flattening: refers to the process of transitioning from a certain shape of the workpiece to flatness.

(24) Punching mesh: refers to the mesh-like holes punched out on the workpiece with a die on an ordinary punch or CNC punch.

(25) Reaming: refers to the process of processing small holes on a workpiece into large holes with a drill or milling cutter.
