Abstract

The present invention relates to a skiving device for processing a heat dissipation fin and, more specifically, to a skiving device for processing a heat dissipation fin, wherein a base plate supporting an object for processing of the heat dissipation fin can be firmly fixed while the inclined degree of the base plate, that is, the inclination in the vertical direction, can be automatically and precisely adjusted, so that a heat dissipation fin having a required thickness and pitch can be precisely formed. Therefore, the skiving device can remarkably reduce occurrence of errors and the defect rate.

The present invention relates to a heat sink manufacturing method and system and, more specifically, to a heat sink manufacturing method and system for providing support so that a heat sink with enhanced heat dissipation efficiency can be quickly and efficiently manufactured. To this end, the heat sink manufacturing method comprises the steps of: determining, on the basis of information about the angle formed between a skiving cutter and a processing surface of an object, at least one cutting line in one direction from one side point on the processing surface; individually deriving, on the basis of the material characteristics of the object and the shape of a heat sink to be manufactured, fin-specific forward and backward lengths of the skiving cutter according to the separation distance of the at least one cutting line separated from the one side point; separating, on the basis of the fin-specific forward and backward lengths, at least one auxiliary fin and one main fin from the object by sequentially moving the skiving cutter forward and backward along the at least one cutting line; and processing the one main fin so that same stands upright relative to a base plate on which the object is stacked, so as to manufacture a heat sink formed in the shape of a plurality of fins branching upward from the one main fin.
