A Korean manufacturer of hydraulic components and fittings was looking for a more efficient and safer deburring solution for the crossbore of a ball valve. The goal was to automate the process if possible. Up to this date, workmen removed the burrs of the bore edge elaborately by hand with a brush.
The deburring of crossbores with bore-Ø-ratio of 1:1 represented a particular challenge for HEULE. The solutions that were available so far could not cope with the extreme sloping of a 1:1 bore. A complete new approach was needed. HEULE found the answer to the problem by making use of new machine capabilities on one hand and by developing a special version of the COFA tool (COFA-X) on the other hand. Combining the two elements led to the success.
- Speed: 10 m/min
- Feed: 0.06 mm/U
- Coolant: external coolant
The fact that the deburring could be carried out in an automated process together with the considerably improved reliabilty resulted in significant savings.
