Filter Tube

Description

An American subcontractor to the automotive industry faced the problem that the manual deburring of his filter tubes was too labourious and unreliable. In addition, too many bad parts were resulting. His target was to automate the deburring process and to machine the part completely on his vertical milling machine.

Customer benefits

Customer benefits

The complete machining of part on the milling center replaces the manual process. At the same time, the customer achieves a reliable process and reduces the number of bad parts significantly.

Savings:
- Manual process
- Bad parts
- Less quality checking work
- Better quality

The resulting longer cycle time is more than compensated by the above savings.
