Key Terms of Machining Sheet Metal Processing
With the popularity of machining sheet metal, more and more people are interested in the terminology of sheet metal processing. So let's take a look at what terms we often need to know during processing.
1. Cutting material: refers to the technological process in which the material passes through the shearing machine to obtain a rectangular workpiece.
2. Blanking: refers to the process of the workpiece being punched by sheet metal laser cutting or CNC punching.
3. Blanking: refers to the process of using molds to obtain product shapes on ordinary punches or other equipment.
4. Punching: refers to the process of machining sheet metal workpieces with ordinary punches and molds.
5. Bending: refers to the process of forming a workpiece by a bending machine.
6. Forming: refers to the process of deforming the workpiece by using a Mold on an ordinary punch or other equipment.
7. Hole extraction: also called "flanging", which refers to the process of forming a round hole on a workpiece using a mold on a common punch or other equipment.
8. Tapping: refers to the process of machining internal threads on the workpiece.
9. Reaming: refers to the process of processing small holes on a workpiece into large holes with a drill or milling cutter.
10. Counterbore: refers to the process of processing taper holes in the workpiece to match the connecting parts like countersunk screws.
11. 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.
12. 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.
13. pull the nut: 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.
14. Pull riveting: refers to the technological process of using a riveting gun as a tool to tightly connect two or more workpieces together with rivets.
15. Riveting: The process of connecting two or more workpieces face-to-face with rivets.
The parts are counterbored first.
16. Punching convex hull: refers to the process of forming a convex shape of a workpiece with a die on a punch or hydraulic press.
17. Punching and tearing: also called "punching bridge", refers to the process of forming a workpiece into a bridge-like shape in a punch or hydraulic press with a mold.
18. Stamping: refers to the process of stamping out characters, symbols or other imprints on the workpiece using a mold.
19. Corner cutting: refers to the process of cutting off the corners of the workpiece using a die on a punch or hydraulic press.
20. Punching mesh: refers to the mesh punched out of the workpiece with a die on an ordinary punch or CNC punch.
21. Flattening: refers to the process of transitioning from a certain shaped workpiece to flattening.
22. Drilling: refers to the technological process of drilling a workpiece with a drill bit on a drilling machine or a Milling Machine.
23. Chamfering: refers to the process of processing the sharp corners of the workpiece using molds, files, grinders, etc.
24. Leveling: refers to the process of using other equipment to level the workpiece before and after the workpiece is uneven.
25. Threading back: refers to the process of the second thread restoration of the pre-tapping workpiece.
26. Deburring: refers to the process of removing the burrs of the workpiece with a grinder, file and other tools during the sheet metal processing of the workpiece, so that the processing part of the workpiece is smooth and level.
27. Argon arc welding: refers to the process in which the workpiece and the workpiece are connected by an argon arc welding machine at the edge or joint of the workpiece. Among them, it is divided into intermittent welding, full welding, etc., which should be clearly marked on the drawing.
28. Butt welding: also known as: "spot welding", refers to the process of welding and connecting workpieces face-to-face by a butt welding machine.
29. Plant welding: refers to the process of firmly welding plant welding screws on the workpiece with a plant welding gun.
30. Others: break difference, shape extraction (die), back pressure, extraction (tapping after extraction), counterbored hole.
