Proposed Solution
Proposed Solution
We have suggested the proven COFA tool system which was the first tool worldwide featuring the ability to deburr even and uneven bore edges forward and backward in one single pass. It removes the burrs radially from the bore edges without requiring to turn the work piece or to stop the spindle.
In order to deburr the large diameter, a tool holder equipped with the COFA 12 Cassette Tool with an S-type spring has been selected.
Machining parameters:
Speed: 300 rpm
Cutting speed vc: 60 m/min
Feed 0.15 mm/rev.
The large unevenness requires low cutting values.
