mold and die manufacturing, PG grinding vs EDM are both widely used processes for producing precision punches, inserts, and tooling components. As each method has its own strengths, selecting the correct process is critical to achieving the required accuracy, surface condition, and tooling performance. This artical aims to guild mold engineers understanding when to choose PG grinding instead of EDM so that can improve quality and efficiency. Surface Finish Requirements Surface finish is another significant factor when choosing PG grinding vs EDM. PG grinding typically gets a smoother surface finish without recast layers or heat-affected zones while EDM surface often require secondary finishing to remove recast layers or improve
