Mechanical polishing

Mechanical polishing is a surface smoothening technique known for its craftsmanship. It involves abrasive materials and compounds to remove surface imperfections and create a smooth, reflective finish. It is labor-intensive process and requires appropriate techniques and methods depending on the object to be treated.

Grinding and polishing

Takes from one to several days depending on the case

In general, grinding is far more aggressive abrading operation than polishing and buffing. It is effective to remove dents, tool marks, deep scratches, and defects. Polishing focuses on removing grinding lines, scratches, pits, mold marks, parting lines, and surface defects to deliver high-quality shine on the surface. Buffing smoothens the minor scratches and gives a final shiny touch to the surface.

In short, surface preparation requires special attention and an appropriate technique to achieve a uniform, mirror-like and defect-free finish.

Benefits of Mechanical Polishing

  • allows for greater customisation, achieving different finishes specifically for your needs.
  • Improves surface finish
  • Reduces friction of the product
  • Makes surface easier to clean
  • Ensures adhesion of a new coating
  • Improves aesthetic appeal.
