tarkkuusjyrsinnän

Tarkkuusjyrsintä, known in English as precision milling, is a subtractive manufacturing process used to create parts with high dimensional accuracy and fine surface finishes. It involves the use of a rotating cutting tool to remove material from a workpiece. This process is typically performed on a milling machine, which can be either manual or computer numerical control (CNC) operated. CNC milling machines offer greater precision and repeatability due to their automated nature, allowing for complex geometries and tight tolerances.

The workpiece is held stationary or moved against the rotating tool, which can move in multiple axes, often three, four, or even five. This multi-axis capability allows for the machining of intricate shapes and contours that would be difficult or impossible with simpler milling techniques. Precision milling is employed across various industries, including aerospace, medical device manufacturing, automotive, and electronics, where the demand for highly accurate and reliable components is critical.

Materials that can be precision milled include a wide range of metals such as aluminum, steel, titanium, and brass, as well as plastics and composites. The choice of cutting tool, material, and milling parameters are crucial for achieving the desired precision and surface quality. This process is essential for producing components like molds, dies, prototypes, and specialized machine parts that require exact specifications.
