Technical Know-How | Are Broken or Detached Beads in Wire Saw Cutting a Quality Problem? A Quick Self-Check Guide
Jun 01,2026
When cutting reinforced concrete with a diamond wire saw, encountering broken or detached beads often leads people to immediately think, "This wire saw is of poor quality." But hold your judgment — you only need to focus on one key point: check whether there is obvious crush deformation on the wire saw surface.
If the wire body shows twisting or crush deformation, it is mostly caused by improper operation during construction. Issues such as an overly narrow kerf, imbalance in tension control, or deviation in cutting path can subject the beads to sustained abnormal compression and impact, leading to chipping, breakage, or detachment. These situations are not classified as quality problems.
Conversely, if the wire saw is visually intact with no crush deformation, yet the beads still exhibit abnormal wear or detachment, then it is more likely to be a quality-related defect.
By assessing the actual physical condition of the wire saw, you can accurately identify the root cause of the issue and make targeted adjustments to your cutting techniques to minimise losses.
