Title:
METHOD AND DEVICE FOR FORMING GROOVE HAVING SMALL SECTIONAL AREA TO SURFACE OF BODY
Document Type and Number:
Japanese Patent JPS6234627
Kind Code:
A
Abstract:
The invention relates to a method of impressing channels having a cross-sectional area of less than 1 mm2, notably less than 3000 mu m2, into the surface of an object, notably for the formation of damping channels of ink jet printer heads. The impression of channels having a small cross-sectional area can be performed with high precision by inserting a wire-shaped element (5) between the surfaces of the object (2) and of a plane die (1) in the position of the channel (3, 4, 12) to be formed, after which the die (1) is pressed until it contacts the surface of the object (2).
