Abstract

[Problem] To provide a fixed-abrasive-grain wire-saw that enables improved workpiece cutting plane accuracy and grinding efficiency and further allows for a longer product service life, a method for manufacturing the fixed-abrasive-grain wire-saw, and a method for cutting a work piece using the fixed-abrasive-grain wire-saw. [Solution] When abrasive grains (2) are to be affixed to the external peripheral surface of a metallic core wire (1), a plurality of transfer rollers (18) provided with a plurality of very small holes (18a) filled with an adhesive (3a) are used to transfer the adhesive (3a) onto the external peripheral surface of the metallic core wire, whereby a plurality of lines (li) of a punctate adhesive layer (3) axially arranged in straight lines at a regular pitch are formed on the metallic core wire; and, after being provisionally bonded to the adhesive layer, the abrasive grains are permanently bonded by electrodeposition on a metallic plating layer (4).

Description

technical field

[0001] The present invention relates to a fixed abrasive wire saw suitable for cutting and processing workpieces made of hard and brittle materials such as silicon, sapphire, silicon carbide, ceramic materials, magnetic materials, etc. The cutting method of the above-mentioned workpiece. Background technique

[0002] As a kind of wire saw used for cutting and processing hard and brittle materials such as silicon, sapphire, and magnetic materials, in the past, abrasive grains composed of diamond etc. Fixed-grain wire saws in which deposited metal plating is fixed are known. And, as a representative manufacturing method thereof, Patent Document 1 discloses a method of passing electricity through a metallic steel wire that has settled in an abrasive grain layer in a plating bath.

[0003] The fixed abrasive wire saw formed by such electrodeposition has the advantages of high retention force of abrasive grains and difficulty in threshing, but because the abrasi...
