A roller bearing manufacturer in South Korea wanted to implement the most cost efficient method to drill and deburr holes into a bearing flange into their new development.
HEULE proposed two VEX-S combination drilling tools, for each diameter one. The combination of drilling and chamfering at the front and the back of the bore reduces the three different operation steps to a single on.
- Drilling Ø8.8 mm & Ø7.1 mm:
Working speed: 88 m/min
Working feed: 0.25 mm/rev.
- Front and Back chamfer
Working speed: 88 m/min.
Working feed: 0.2 mm/rev.
- Cycle Time for both operations: 3 sec.
The benefits are enormous. Since this solution divides the cycle time by two, the production time saved amounts to 20'000 hours (2 million parts x 12 bores x 3 sec.). The cost savings not only concern the production time but also the investments in machinery that have been rendered redundant.
