Are your slabs not perfectly flat? Breton has created the right product for you.
Breton launches MiterWave, the hardware/software package that can perform highly accurate 45° cuts even on non-flat slabs.
Slabs, especially ceramic slabs, are often - if not almost always - not perfectly flat or planar: stresses, warps or imperfect calibrations are the order of the day, and miters become a disaster.
