Overview

Rubber Control and Centreless Grinding Abrasives are specialized wheels used for precision grinding of rubber-coated rolls, cylindrical components, and parts requiring exacting dimensional control without the use of centers. These abrasives are designed to maintain the geometry, smooth finish, and concentricity of the workpiece even under high-speed operations and soft material conditions like rubber or polymer.

Whether it’s rubber roll grinding or through-feed/bar grinding, our abrasives provide superior wear resistance, temperature stability, and high form retention, making them ideal for continuous production environments.

Applications

  • Rubber roll grinding in printing, textile, and paper industries.
  • Centreless grinding of metal rods, bars, and tubes.
  • Polishing and precision sizing of elastomer-coated rollers.
  • Grinding of control wheels in centreless machines.
  • Automotive valve, piston pin, and transmission shaft manufacturing.
  • Feed rollers, conveyor rollers, and rubber bushes finishing.
  • Bar grinding for hydraulic, bearing, and steel plants.

Features & Benefits

  • Precision grinding for soft and elastic rubber materials.
  • High resilience to deformation for uniform results.
  • Minimal wheel dressing, longer operational cycles.
  • Special bond systems for rubber, polymer, and PU applications.
  • Available in control wheel (resin/rubber bond) and grinding wheel variants.
  • Superior load-bearing and vibration absorption properties.
