säikeistysprosessi

Säikeistysprosessi is a Finnish term that translates to "threading process" in English. It refers to a method of creating or forming threads on a solid cylindrical or conical surface. This process is commonly used in manufacturing and metalworking to produce screws, bolts, and other threaded components.

There are several ways to achieve a säikeistysprosessi. One common method is using a die, a tool with hardened cutting edges that can be rotated or pushed along the workpiece. The die cuts the threads into the material as it moves. Another technique involves a thread-cutting lathe, where a specialized cutting tool moves along the rotating workpiece, gradually removing material to form the desired thread profile.

Alternatively, some methods involve deforming the material rather than cutting it. Thread rolling, for instance, uses hardened dies to press the material into the shape of the thread. This process is often faster and can produce stronger threads as it doesn't remove material and work-hardens the surface. The choice of method depends on factors such as the material being worked with, the required precision, the production volume, and the desired thread characteristics. Säikeistysprosessi is a fundamental manufacturing operation enabling the creation of fasteners and many other mechanical components.
