Abstract

The invention relates to the technical field of a fixed abrasive wire saw and a preparation method thereof. The fixed abrasive wire saw of the invention includes: a wire; a bonding layer located on the surface of the wire, including a metal or alloy layer formed on the surface of the wire; A plurality of abrasive particles within the metal or alloy layer; and a surface layer, the surface layer being one or more composite layers covering the surface of the bonding layer, the surface layer being made of organic material, metal and / or alloy material , and may contain filler abrasives filled therebetween. The present invention can solve the problem that the bonding strength of the abrasive particles decreases with the loss of the surface layer, the clogging of the chips during the cutting process, and the circulation of the cooling liquid or lubricating liquid. Configured to improve the cut flatness of the workpiece.

Description

technical field [0001] The invention relates to the technical field of a wire saw and a preparation method thereof, in particular to a fixed abrasive wire saw and a preparation method thereof. Background technique [0002] Wire saw cutting is a processing method for cutting semiconductors, crystals, various single crystals, magnetic materials, precision ceramics, and other hard and brittle materials. Free abrasive wire saws have been widely used in the slicing process of semiconductor wafers and solar silicon wafers. It uses steel wires to drive free abrasives (abrasive + liquid) to remove materials. It is easy to pollute the environment, lead to industrial waste, and its processing efficiency is low, so the development of fixed abrasive wire saws has become an inevitable trend in the industry. Compared with the free abrasive wire saw, the advantage of the fixed abrasive wire saw is that the material removal rate can be improved and the processing abrasive can be fully util...
