AI Technical Summary
Technical Problem
Conventional saw wires exhibit insufficient durability, leading to frequent breakage during cutting operations.
Method used
A metal wire made of tungsten or a tungsten alloy with a high tungsten content and abrasive particles electrodeposited on its surface, designed to withstand a fatigue test with a maximum stress of 4400 MPa for 20,000 cycles or more, and a saw wire configuration that allows for reuse by regenerating abrasive particles.
Benefits of technology
The solution provides highly durable metal and saw wires that can withstand repeated cutting cycles without failure, reducing material waste and increasing efficiency in cutting processes.
