Spindle fall

The spindle camber is a term from manufacturing technology and describes the inclination of a vertical milling machine spindle during milling in order to avoid re-cutting, the so-called re - cutting effect , of the tool cutting .

After the cutting process, the cutting edges turn over the already manufactured workpiece surface and remove a thin chip . This damages the cutting edges and leads to an uneven surface. Alternatively, the machine table can also be tilted, but this is rarely the case.

The camber angle should be between 0.005 ° and 0.03 ° in the feed direction . If the camber is set too large, the cutting edges will be damaged. The camber also creates a slightly concave surface during milling , but in most cases it can be neglected.
