Sheet milling

Sheet milling is a machining technique that, like drilling and turning, falls into the category of cutting techniques. Often, a combination of several cutting methods are used. Milling is often performed at the beginning of a process chain, since it is used to achieve the part’s general shape. While turning is used mainly with round parts, however, milling allows free choice of part geometry.

Areas of application for cutting manufacturing techniques

Cutting methods such as drilling are used in the manufacture of precision shims when laser and punching techniques have reached their limits. This is especially true of laminated shim stock. For parts made of laminate that have been bonded across their entire surface, lasering can often not be used because this thermal technique causes the adhesive to melt at the edges of the cut. Punching can be performed on laminated shim stock, but it is not particularly suited to the material. The lifting force presses the individual foil layers together, making them more difficult to separate later. Cutting methods for metal sheet such as drilling, turning, and milling are therefore the preferred techniques for high-quality precision shims made of laminate.
