A Korean manufacturer of hydraulic components and
bolt connections / fittings was looking for a safer and more efficient solution for deburring the crossbore of a ball valve. The aim was to ideally automate the process. Until then, employees were laboriously removing the burrs from the bore edges by hand with a brush.

|Cross bore||Ø10.4 mm|
|Main bore||Ø10.4 mm|
|Machine||DOOSAN CNC machine|
The deburring of crossbores with a 1:1 bore diameter ratio posed a unique challenge for HEULE. The tool solutions that were available so far could not cope with the extreme unevenness of a 1:1 bore. HEULE had to find a completely new approach to the solution. They found it by using both new machine capabilities and by developing a special version of the COFA tool (COFA-X). The combination led to success.
