Coolant Selection and Management for Wire Sawing

Diamond wire saws are specialized cutting machines engineered for precision cutting of hard materials in laboratory environments. Fine particles of engineered diamond embedded in a diamond-coated cutting wire enable smooth cuts with limited kerf loss and minimal mechanical stress. Modern wire saw machines feature high repeatability across materials and incorporate CNC systems with precision carriages, drive elements, and endless diamond configurations for efficient and reproducible sample preparation.

What is a Diamond Wire Saw?

A diamond wire saw is a wire-based cutting tool where a thin diamond wire, coated with precise diamond particles, moves continuously to cut materials with exceptional accuracy. The cutting force in a diamond wire saw is considerably lower than abrasive wheel cutting, enabling precise cuts and smoother surfaces on very hard materials.
