A diamond wire saw stands as a specialised flexible cutting implement, structured with diamond beads, springs, gaskets and a core steel wire rope. The diamond beads are secured onto the wire rope at set intervals via injection moulding or adhesive bonding, making it widely applicable for profiling shaped stone slabs, dressing raw stone blocks, quarrying stone materials, and cutting construction parts like bridges and concrete components.
The protruding height of diamond grains on the beads is a critical factor: it directly determines cutting efficiency, service life and overall operational cost of the wire saw. Higher diamond protrusion creates larger spaces for chip removal and water cooling, boosting cutting performance; it also means longer effective working time for diamond grains, thus prolonging the tool’s service life.
Sustaining optimal diamond protrusion demands a bond matrix with strong diamond-holding capacity and a wear rate that matches the diamond grains perfectly.
To meet this demand, Sagwell has launched three tailored ultrafine iron powder grades: UHA, UHD and ZF. These powders begin liquid-phase transition at 687.5℃, achieve high alloying with other matrix powders, deliver exceptional diamond retention and stable high diamond protrusion. They have already gained wide adoption among numerous diamond wire saw producers.
