Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong grit abrasive for the desired finish.Consult abrasive manufacturer guidelines to select the appropriate grit for the intended surface finish and material compatibility.
Applying excessive pressure, leading to material deformation or uneven abrasion.Apply consistent, moderate pressure and use controlled, overlapping strokes to ensure uniform material removal and a consistent finish.

Common Applications

  • Surface preparation for decorative finishes
  • Deburring and edge refinement of metal parts
  • Precision polishing of optical components

⚠️ Engineering Warnings

  • Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when handling and working with metal sheets.
  • Ensure proper ventilation when performing abrasive or polishing operations to avoid inhalation of airborne particles.
