【発明の名称】マルチディスクカッターとその製造法
Document Type and Number:
Japanese Patent JP2791559
Kind Code:
B2
Abstract:
An abrasive multi-disc cutter is formed by uniformly coating a cylindrical holder with a mixture of diamond powder and resin. The holder is rotated about its longitudinal axis while one or more beams of laser energy are used to ablate the resin for forming a plurality of annular depressions in the coating, the depressions being equally spaced along the longitudinal axis of the cylindrical holder. An abrasive annular cutting disc is thereby provided between each pair of successive annular depressions. The cutter is used to cut a plurality of parallel, spaced ink cavities in a piezoelectric substrate forming part of an ink jet printer printhead.
