Pre-polishing

Within the pre-polishing section, we offer a number of products for creating special finishes. There are products for surface finishing, structuring, and pre-polishing.

Unitized

Tools made of compressed nonwoven abrasive containing a high concentration of evenly distributed abrasive grain. The material holds its shape and enables easy surface finishing, removal of annealing colours or blending after weld seam removal.

Unitized tools are ideal for pre-polishing as they can remove light scratches without changing the part dimensions. Wheels can be dressed to a profile to fit specific shapes.

Common areas of application include aviation and aerospace industries, as well as orthopaedics and medical technology.

Processing tasks:

  • Removal of rust, scale, scratches or coatings
  • Universal cleaning
  • Deburring
  • Elimination of heavy burrs as well as medium-sized pinholes, flaws or parting lines
  • Rounding of edges
  • Front face processing
  • Blending
  • Fine machining of surfaces
  • Preparing surfaces for polishing

Materials that can be processed:

  • Alloy and high-alloy steel
  • Aluminium
  • Brass
  • Copper
  • Titanium
  • Platinum

Machines:

  • Angle grinders
  • Mini angle grinders
  • Variable-speed angle grinders
  • Straight grinders
  • Bench grinders

Convolute

These versatile tools are suitable for deburring, cleaning, or repairing surfaces. They can also be used for standardising surfaces.

Convolute wheels are made of nonwoven abrasive which is wound around a core. They are offered in multiple densities, abrasives, and grit sizes to suit a variety of tasks.

These products have been designed for stationary use. Denser grades are suitable for deburring or applying a grained finish. More open specifications can lightly clean a surface or conform to irregular shapes.

Main areas of application for these are also the aviation and aerospace industry as well as orthopaedics and medical technology.

Processing tasks:

  • Matting surfaces
  • Reworking turbine blades
  • Processing surgical instruments
  • Finishing of implants
  • Demanding surface processing
  • Blending cast or parting lines
  • Surface cleaning
  • Finishing

Materials that can be processed:

  • Stainless steel (INOX)
  • Aluminium
  • Zinc
  • Brass
  • Pressure castings
  • Titanium
  • Cobalt chrome
  • Nickel alloys

Finishing rolls:

Special tools which are suitable for fine finishing or structuring large areas. Great choice for finishing stainless steel (INOX).
