Abrasive Belts & Brush Rollers

Select the right abrasive consumables for efficient deburring, edge rounding and surface preparation. These selection guides cover abrasive belts, grit choice and brush rollers for our deburring machines.

Abrasive Belt Selection

Three abrasive materials cover carbon steel, stainless steel, aluminum and general metal processing.

Abrasive Material Available Grits Typical Applications Key Characteristics
Silicon Carbide (SiC)P60 / P80 / P120Carbon steel, iron and general metal processingSharp cutting action, suitable for effective burr and oxide removal
Aluminum Oxide (Al₂O₃)P80 / P120 / P180 / P240 / P320 / P400Stainless steel, copper and general metal finishingDurable abrasive performance, suitable for deburring and surface preparation
Flexible Cloth BaseP120 / P180 / P240 / P320 / P400Aluminum and applications requiring a more flexible abrasiveFlexible contact, suitable for fine deburring and surface finishing
Grit Reference

Grit Effect Reference

How each grit grade affects cutting action, deburring capability and surface finish — from P40 (coarse) to P400 (extra fine).

Grit Cutting Action Deburring Capability Surface Finish Typical Application
P40Very HighVery StrongCoarseHeavy material removal and severe burrs
P60HighStrongCoarseHeavy deburring and oxide removal
P80HighStrongMedium-CoarseGeneral-purpose deburring
P120MediumModerateMedium-FineFine deburring and edge treatment
P180Medium-LowModerateFineFine edge treatment and surface preparation
P240LowLight–ModerateFineSmoother surface preparation
P320LowLightVery FineFine surface preparation and finishing
P400Very LowVery LightExtra FineVery fine surface preparation and finishing

Trend: coarser grit (P40 → P60 → P80 → …) gives higher cutting action, higher material removal and a coarser surface pattern; finer grit gives lower material removal and a smoother surface appearance.

Selection Guide

How to Select the Right Grit

Five steps to choose the correct grit for your workpiece material and finish requirement.

  1. Identify the workpiece material

    Carbon steel & iron → Silicon Carbide (SiC). Stainless steel & copper → Aluminum Oxide (Al₂O₃). Aluminum → flexible cloth backing.

  2. Check the burr condition

    Heavy / sharp burrs → start with a coarser grit. Medium burrs → medium grit. Light / fine burrs → finer grit.

  3. Define the edge requirement

    Fast burr removal → coarser grit. General deburring → medium grit. Fine edge treatment → finer grit. Edge rounding → medium to fine grit.

  4. Define the surface finish

    Coarser grit = higher material removal + stronger burr removal + more pronounced scratch pattern. Finer grit = smoother surface appearance.

  5. Select the final grit

    Processing TaskRecommended Grit
    Heavy DeburringP60–P80
    General DeburringP80–P120
    Fine Deburring / Edge TreatmentP120–P240
    Fine Surface Preparation / FinishingP180–P400

Brush Rollers

Brush Roller Selection

Brush rollers are available in different abrasive filament grades to suit different levels of deburring and edge rounding.

Brush Grade Processing Effect Typical Application
Coarse GradeStronger burr removalHeavy burrs and aggressive edge treatment
Medium GradeBalanced deburring & edge roundingGeneral sheet metal processing
Fine GradeFiner edge treatmentFine deburring and surface preparation

Abrasive selection is application-dependent. The optimal abrasive material and grit may vary with workpiece material, sheet thickness, burr size, required edge radius and desired surface finish. We recommend testing your workpiece before finalizing the specification.
