Open-Structure Wheels for Optical and PCD Grinding
Vitrified bond's porous matrix runs cooler, holds profile geometry under continuous dress cycles, and accepts coolant efficiently—eliminating thermal damage on heat-sensitive workpieces.
Bond structure engineered for precision-critical applications
Cooler cut, lower thermal risk
Efficient fluid delivery to the cut
Form held from first part to last
High porosity dissipates heat at the grinding zone, protecting glass surfaces and PCD inserts from micro-cracking and bond degradation under sustained passes.
The rigid glass matrix resists lateral deflection and retains edge geometry across continuous dress cycles—critical for optical lens blanks and tight-tolerance PCD profiles.
Open pore channels carry coolant directly to the diamond-workpiece interface, reducing friction and flushing swarf before it can re-embed in the bond matrix.
