The requirements of polishing mechanical parts

Industrial polishing of mechanical parts eliminates surface peaks to lower roughness, reduce friction, wear, noise, dynamic fatigue and improve part performance.

The benefits are measurable on many levels:

  • Higher engine efficiency
  • Increased mechanical performance
  • Extended part life
  • Reduced vibration, noise and energy consumption

The industrial polishing of mechanical parts can be manual or robotized, from the simplest to the most complex and concerns many mechanical and industrial parts.

The performance and quality of the compounds and buffing mops used is a key element to obtain the expected roughness without altering the geometry of the part.

Which solutions for the polishing of mechanical parts?

Compound liquid buffing mop

Technical liquid polishing compounds

To adapt to the requirements of automatic robotic or barrel polishing, MERARD has duplicated its best solid polishing compounds into liquid polishing compounds, with a special focus on finishing and mirror polishing.

  • Polishing compounds with high concentration of polishing abrasives to increase productivity and performance
  • Good control of viscosities for easy machine adjustments
  • Flexibility and adaptation to small and large volumes (available from 500ml to several tens of thousands of tons)
