Green Resin Wheel for Glass Edging Machines

Why shallow grinding lines remain before polishing

When shallow, regular grinding lines remain on a glass edge after several wheels, the cause is often misunderstood. In a typical edging sequence, diamond wheels perform rough grinding and shaping; the resin wheel then refines the remaining marks; and the polishing wheel raises the final brightness.

If the resin wheel does not have the correct cutting action or mark-removal capability for the process, shallow lines can pass into the polishing stage. A polishing wheel can improve brightness, but it cannot reliably remove marks that should have been refined at the preceding resin-wheel position.

For this condition, review the resin-wheel position first: its diameter, bore, working layer, grit, pressure, coolant and the prior diamond-wheel result. A correctly matched green resin wheel can create a finer, more even edge surface and provide a better base for final polishing. Every stage has its role: diamond wheel for grinding, resin wheel for mark refinement and polishing wheel for brightness.
