Deburring Bores on Hard-to-Reach Irregular Surfaces
Challenge:
This manufacturer machines V-8 crankshafts that consist of a main bore that breaks out into seven different surfaces, some which are angled/irregular cast surfaces. They needed a tool solution that was able to reach all of the large exit burrs on the part.
Application details:
•Machine: Custom, no coolant
•Material: steel
Solution:
The solution from HEULE is a special C12 COFA with a 20° “M” blade and “S” spring.
Machining parameters:
Feed: 1.25 mm/s
Speed” 280 RPM
Results:
The COFA tool has a cutting blade which is able to pivot and successfully deburr all of the flat and angled/irregular surfaces by entering through the main bore to reach the seven different bores. The customer is pleased with the automated solution and the tool performance.
