Spherical pore-forming is our own patented process for putting controlled spherical voids into the working layer of a diamond tool. It runs across the ceramic range: edge and trimming wheels, chamfering wheels, and the glass and slab wheels.
What the pores do
- Give swarf somewhere to go instead of packing against the cutting face.
- Let coolant reach the face rather than riding on the surface.
- Break up the contact area so the tool runs cooler.
Why that shows up as edge quality
On brittle materials, heat and packed swarf are what cause glazing, and glazing is what causes chipping. A wheel that clears its own chips keeps cutting at a lower temperature, so the edge stays intact. That is the practical reason the structure exists. It is not a laboratory claim.
Where it is not the answer
If your edges are chipping because of flange condition, feed speed or lack of support, pores will not save you. Check those first. The structure helps a tool that is otherwise set up correctly.
