Q
Hello, currently have both Aluminum Oxide & Silicon Carbide PSA 4" pads that we use to polish Glass Die facets.
Can you advise on advantages of one type over another?
We use these for optical polish after grind.
A
For a particular abrasive "grit" size, silicon carbide particles are harder and sharper than aluminum oxide. SC will cut a surface faster, but AO will typically provide a smoother finish.
