ABSTRACT:
A method of making a number of adjacent ducts with a required duct side and duct spacing in a duct plate for an inkjet print-head. The method includes the steps of pressing a non-rotating toothed bit from a starting position into the duct plate, moving the bit and the duct plate relatively to one another in such manner that a first groove is cut in the duct plate and returning the bit and/or duct plate to the starting position. The bit is then moved relatively to the duct in a direction of the first groove in such a manner that a subsequent tooth of the bit situated next to the first tooth comes to lie just above the first groove. These steps are then repeated in such manner that the depth of the grooves correspond to the required duct depth.
