How to Use Zirconia Strips for Metal Grinding

Quick Answer

For effective metal grinding, choose zirconia strips in the appropriate grit, secure your work, and use light, consistent pressure with a back-and-forth motion. Avoid overheating the metal by letting the abrasive do the work.

Step-by-Step Guide to Using Zirconia Strips on Metal

1. Select the Right Grit: Choose 120 grit for general blending and light deburring. For heavier stock removal, consider a coarser grit if available. Check the grit before starting; using too fine a grit on heavy material will waste time and strip.
2. Secure Your Workpiece: Clamp the metal piece firmly to a stable surface to prevent movement and ensure even grinding. A loose workpiece can cause the strip to grab and tear, leading to injury or poor results.
3. Use Light, Even Pressure: Hold the strip flat against the metal and apply light pressure, moving in a back-and-forth or circular motion. Let the abrasive do the cutting. Pressing too hard can overheat the metal and dull the zirconia grain quickly.
4. Keep the Strip Moving: Avoid lingering in one spot to prevent heat buildup and uneven material removal. Keep a steady rhythm. Heat discoloration on the metal is a sign you are moving too slowly or pressing too hard.
5. Monitor Strip Wear: Inspect the strip regularly. When it becomes smooth or loses its cut, replace it with a fresh one to maintain efficiency. A worn strip increases friction and heat, which can damage the workpiece.
6. Finish with a Finer Grit (Optional): If a smoother finish is needed, switch to a finer grit strip (e.g., 220 or higher) and repeat the process with lighter pressure. Always progress from coarse to fine for a clean, uniform finish.
