Crankshaft

The replacement of manual processes with automated ones.

Customer application

This crankshaft's manufacturer is a supplier to the Chinese automobile industry. These oil bores have been manually deburred until now. Due to customer complaints, they were searching for a more stable process. Because they lacked an automated tool solution for deburring crossbores with a bore diameter ratio of nearly 1:1.

Bore diameter	Ø8.0 mm intersecting with main bore Ø8.5 mm
Material	42CrMoA
editing	horizontal
Volume	1 million bores per year

Solution

This application is a case for HEULE's X-BORES technology. The COFA-X tool has been designed for deburring crossbores with a bore diameter ratio of 1:1. This means that the deburring point will be accessed via the crossbore.
