Threading types

Metric thread as partial profile with pitches from 0,5 - 2,5 mm. The minimum possible thread diameters should be
observed depending on the pitch. Thread with cutting interruptions, for example safety grooves, can be manufactured,
if these are phased.

Machining

Constant infeed between 0,05 - 0,09 mm per passage in X -Axis under a flank infeed
in Z of 28°.

The number of passages should be calculated according to the threaddepth. In case
of constant cutting the machining can be done dry or wet. With interrupted cut the
machining should be done dry.
Modified flank infeed
