Deburring and Particle Removal, Blade Sharpening, Fatigue Strength

Burrs and particles can be a problem during assembly or later during operations and must be reliably and cost-effectively removed. POLIGRAT processes achieve this reliably and cost-effectively by means of chemical or electrolytic treatment.

The principle

POLIGRAT processes remove burrs and particles from the entire surface. At the same time, the surface is smoothed and polished. This is effected even in inaccessible places such as holes, threads and indentations and is largely independent of form, structure and size of the parts as well as the hardness and toughness of the material.

During processing a thin layer of material is removed from the entire surface of the parts without placing them under stress. Processing removes flakes, debris and particles as well as impurities, micro-cracks and local structural damage. Burrs up to a size of approx. 0.5 mm are safely removed due to the removal of larger amounts along the edges and on the corners.

Parts of virtually any shape and size can be processed individually or on racks. High volume small parts are treated in bulk material in drums, while wires and bands are treated on wheels. The interior of pipes and drillings are processed by pumping through.

The application

POLIGRAT processes are used anywhere where metal surfaces are subject to increased demands for freedom from burrs and particles as well as function and appearance. These include

  • Deburring and smoothing of parts which have been processed by milling, punching, cutting or laser processing
  • Surfaces with high quality requirements for purity and freedom from particles
  • Parts with complex shapes or bendable forms
  • Hard, tough or soft materials
  • Sharpening of cutting edges and needle tips without deforming
  • Increased fatigue strength in dynamically loaded parts

POLIGRAT processes

POLIGRAT processes for deburring and smoothing are available for virtually all metals and alloys with technical applications. The selection of the most suitable process in each case is determined by the material, the part and special requirements
