It is possible that the blade may have cut into the C/T during contact setup (C/T setup or sensor calibration setup).
When performing contact setup, please use the setup tool sold separately. For inquiries regarding the setup tool, contact your DISCO customer engineer.
Why does it happen?
In contact setup, there is direct contact between the blade and C/T, and the C/T height is measured by causing contact and detecting continuity.
Vitrified bond blades are composed of glass and ceramic materials, and are nonconductive. As a result, even if the blade and C/T are touching, there is a risk that continuity will not be detected and cutting into the C/T will continue.
