Detail of journal bore

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 stopp 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 v_c 60 m/min,
Feed 0.15 mm/rev.
The large unevenness requires low cutting values.

Customer Benefits

The automated deburring process allows a comprehensive machining of the part.

Customer Satisfaction

The customer is fully satisfied by the deburring quality and the process capability.
