Deburring

Problem

Deburring turned parts in series production
Turned parts are produced in very large volumes. High chip removaI rates can be achieved very quickty. Comptex geometries can be produced at the same time, such as cross holes, grooves or controI edges.

Why does the burr need to be removed?
Burr in a part may break in later use. The broken fragment can lead to the failure of entire assemblies and systems (leaks, jamming, etc.).

Solutions to date

ConventionaI solutions are mostly brush applications which aim at breaking off the burr through the impact of filaments. However, this often leads to the burr merely being bent or not removed completely (burr root). Deburring tools frequently generate secondary burr.

The ELKA solution

ELKA binds abrasive grit into an elastic bond within the grinding tool. The elastic bond can reversibly encircle the edge. This removes the burr and burr root completely and yields a defined contour by means ofedge rounding. By adapting the abrasive grit and the elastic bond (hardness), the deburring process is completely controlled and yields a defined rounded contour of 0.002 mm to 2 mm.
