A FIXED ABRASIVE SAWING WIRE AND A METHOD TO PRODUCE SUCH WIRE

摘要

A fixed abrasive sawing wire (100) suitable for sawing hard and brittle materials is disclosed. The sawing wire is of the type wherein hard particles - preferably diamond particles - are pushed into a soft indentation layer that covers a hard steel wire core (110). After indentation particles are fixed further by means of a binding layer. The sawing wire (100) is particular in that the indentation layer is build-up out of two metallic layers: a first metal layer (112) closet to the steel wire core on the top of which a second metal layer (114) is deposited. The first metal is softer than the second metal. The second metal layer (114) is thin in order not to limit the indentation capability of the first metal layer (112). It is conjectured that the second metal layer (114) is like a skin that improves the particle retention capabilities of the fixed abrasive sawing wire (100). Also described are a number of methods to produce such a kind of wire.
