Monofilament metal saw wire

Abstract

Monofilament metal saw wire for a wire saw, wherein the saw wire being provided with a plurality of crimps. The crimps are arranged in at least two different planes, such that, when measured, between measuring rods of a micrometer, over a length comprising crimps in at least two different planes, a circumscribed enveloping D diameter of the saw wire is between 1.05 and 1.50 times a diameter d of the saw wire itself.

Description

technical field [0001] The present invention relates to monofilament type metal sawing wires, and more particularly to monofilament type metal sawing wires for use with wire saws for sawing hard materials such as blocks of silicon or quartz. Background technique [0002] Wire saws are known for sawing hard materials, such as cutting thin slices from silicon blocks. Such wire saws include monofilament-type metal saw wires that are pulled through the silicon block by moving continuously or back and forth against the silicon block. Monofilament type metal sawing wires are usually coated with abrasives to aid in the sawing process. Shortly after the abrasive is applied to the wire, the wire typically enters the cutting zone where the wire contacts the silicon block. The efficiency of the sawing process depends on several parameters, such as the properties of the hard material block to be cut, the speed of the saw wire, etc. The important factor is the ability of the wire to e...

Problems solved by technology

While these solutions allow for better entrainment of the abrasive, changes to the outer surface of the wire are often slow and cumbersome
