Helix milling application

A major focus in milling operations is on reducing the machining time. With specific tool geometries for machining closed, round pockets, it is often possible to eliminate the pre-drilling process. With helix milling, milling paths are programmed with helical entrances that are suitable for pocket dimensions.
On a rendered example component, an operation is highlighted.
Tool overview for the following machining steps:

Roughing

Roughing operations are responsible for most of the chip removal capacity. Special milling strategies such as high-feed machining or trochoidal milling can reduce machining time and thus increase profitability. In addition to tools with indexable inserts and solid carbide milling cutters, high-performance milling cutters with special roughing geometry are used.

Residual material roughing

After roughing, in a second machining step, users machine the residual material, especially in corners and cavities, removing material as constantly as possible. Usually tools with corner radius or high-feed milling cutters are used. In some cases a ball cutter can be used to remove the residual material in corners.
