During contour milling we recommend a lateral infeed of approx. 25 of the end mill diameter while applying 100 immersion depth. The immersion depth is conditional to the milling motor the structure and the stability of the machine. This means a reduction of the values is required when using a less powerful and / or lighter milling motor.
