How to Reduce Scratch Marks from Tooling

The next polishing step reveals deep random scratches from the metal pass. This page outlines the likely causes, practical fixes, and a tooling path you can test on the next pass.

Problem Description

The next polishing step reveals deep random scratches from the metal pass.

Root Cause Analysis

  • Grit progression skipped too far.
  • Segment bond is too aggressive for the target finish.
  • Dust extraction is poor and debris is recutting the slab.

Solution Plan

  • Tighten the grit sequence with an intermediate metal step.
  • Use a calmer bond and slower travel speed.
  • Improve dust pickup or switch to wet grinding for the transition step.

Recommended Product Direction

Medium-bond transition metals for polishing prep.

FAQ

What is the fastest first check for how to reduce scratch marks from tooling?

Start by confirming floor hardness, opening grit, and whether the current bond is exposing fresh diamonds at the right pace.

When should I change tooling instead of machine settings?

If the scratch pattern stays inconsistent after a slower test pass and tool dressing, the bond or grit choice should change before production continues.

How do I get a recommendation for this issue?

Share the machine brand, floor hardness, and the symptom you see. We can suggest a better bond and grit sequence before the next pass.
