Svarvfräsning

Svarvfräsning, also known as turn-milling or milling-turning, is a hybrid machining process that combines the capabilities of both turning and milling operations within a single machine tool. This approach allows for the simultaneous or sequential execution of turning and milling on a workpiece held in a rotating chuck or spindle. The primary advantage of svarvfräsning lies in its ability to produce complex geometries that would typically require multiple machine setups or specialized machines.

In a svarvfräsning operation, the workpiece rotates, similar to a lathe, while a milling tool, mounted on a movable head, engages the rotating material. This allows for the creation of features such as pockets, slots, keyways, and external or internal threads, in addition to the cylindrical surfaces typically produced by turning. The milling head can often be positioned at various angles, enabling the machining of inclined surfaces and other intricate details.

The development of advanced CNC (Computer Numerical Control) systems has been crucial to the widespread adoption of svarvfräsning. These systems precisely control the synchronized movements of the workpiece spindle and the milling head, allowing for highly accurate and repeatable complex part manufacturing. Svarvfräsning machines are particularly beneficial for producing small to medium-sized batches of high-value components, such as those found in the aerospace, automotive, and medical industries, where precision and geometric complexity are paramount.
