<p>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, by pressing a non-rotating toothed bit (50) from a starting position into the duct plate (3), moving the bit and the duct plate relatively to one another in such manner that a first groove is cut in the duct plate, returning the bit and/or duct plate to the starting position, moving the bit 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 come to lie just above the first groove, repeating these steps in such manner that the depth of the grooves correspond to the required duct depth. <IMAGE></p> |
