Fræsarar

Fræsarar is a term used in Icelandic to describe milling machines. These are machine tools that remove material from a workpiece by the use of a rotating cutter. The cutter typically has multiple cutting edges, and it rotates on an axis of rotation. The workpiece is moved against the cutter to create the desired shape.

Milling machines can be used for a wide variety of operations, including shaping, drilling, and grooving. They are commonly used in industries such as manufacturing, aerospace, and automotive. The accuracy and precision offered by milling machines make them essential for producing complex parts and components.

There are several types of milling machines, including horizontal, vertical, and universal milling machines. Horizontal milling machines have a spindle that is parallel to the workpiece, while vertical milling machines have a spindle that is perpendicular to the workpiece. Universal milling machines offer the flexibility to perform both horizontal and vertical milling operations.

The process of milling typically involves setting up the workpiece on the machine table, selecting the appropriate cutting tool, and then feeding the workpiece into the rotating cutter. The speed of the cutter, the depth of cut, and the feed rate are all important parameters that must be controlled to achieve the desired result. Computer numerical control (CNC) has revolutionized milling, allowing for highly automated and precise machining operations.
