Hydraulic press SMG - technological processes and operations
| Press fitting | Press fitting is an assembly operation in which one part is inserted into another under the force of a press. The connection is achieved through interference fit, where the mating surfaces are held together by friction. The process provides strong and precise joints without the use of heat or fasteners. Used in the assembly of bushings, bearings, pins, and other components requiring a tight fit. |

| Sheet stamping | Sheet stamping is a class of operations for forming parts from sheet material using dies. The workpiece is deformed in the tool without significant change in thickness, acquiring the specified shape. This group includes blanking, punching, bending, drawing, and other processes performed on presses. Sheet stamping is the foundation of mass production of body panels, housings, and other thin metal parts. |
| Drawing | Drawing turns a flat blank into a hollow product. The sheet is clamped at the edges while the tool presses the central part, forcing the metal to flow into the die cavity and form walls. This is how cups, caps, housings, and other parts with one open side are produced. |
| Deep drawing | A sheet blank is drawn into the die to a depth significantly exceeding its transverse dimension. The process is carried out in stages, with intermediate transitions, to avoid tears and wrinkles. At each stage, the metal is gradually redistributed, increasing the depth of the part while maintaining wall thickness. This method produces hollow products of complex shape — cylinders, shells, and housings. |
| Bending | Bending gives a sheet blank an angle or curvature. The metal is bent in the die under the force of the press: the outer layers stretch, the inner layers compress, and the middle retains its original length. The operation allows producing parts with the specified geometry without changing the material thickness. |
