Grabener GKS 600 knuckle joint press - description

Knuckle joint press Grabener GKS 600 — 600 ton (ID:76166) is an industrial press with a knuckle-joint mechanism that delivers high force with a short ram stroke. The machine achieves significant pressure at the final stage of the working cycle while maintaining relatively compact dimensions. Used for coining, calibration, and cold stamping operations where a short but powerful force application is required.

Knuckle joint press Grabener - technological processes and operations

Coining Under enormous pressure, the die is pressed into the workpiece, forcing the metal to distribute into the smallest recesses of the tool. As a result, clear reliefs, inscriptions, or patterns are formed on the surface with high accuracy. The metal fills all details of the die, fully reproducing its geometry. Used in the production of coins, medals, and precision parts where relief clarity and dimensional accuracy are essential.
Calibrating A finishing operation that brings the forging to precise dimensions. The workpiece is placed in a calibration die, where under pressure its surface is leveled and the geometry is brought to the specified tolerances. This process eliminates minor shape distortions left after previous operations. As a result, the part receives stable dimensions and a smooth surface without additional machining.
Sheet stamping —
Punching Punching holes in sheet metal is performed in a die: a tool with sharp edges passes through the workpiece, separating material along a closed contour. The process is fast and precise, leaving no burrs when properly set up. Used for producing holes, slots, and cutouts in sheet metal parts.
Blanking Blanking a part from a sheet along a closed contour is performed on a press using a blanking die. The tool passes through the material, separating the finished part from the sheet. The accuracy of the contour and the cleanliness of the edge determine the quality of the final product.
