Common rail

In the low-pressure range, diesel fuel distribution systems also require cleanly deburred bores.

Customer application

Our German customer produces over 1 million Common Rails annually. He was looking for a solution to automate the reverse deburring of the low pressure bore.

WorkpieceCommon Rail
Low pressure bore 2.4 mm
Main bore 9.0 mm
max. Deburring diameter2.8 mm
Material forged case-hardened steel (1,000-1,300 N/mm┬▓)
SNAP_einzeln

Solution

The solution proposed by HEULE is the simple and economical SNAP tool. The edges of the bore are deburred and chamfered without rotating the workpiece or stopping the spindle.

 

ToolSNAP 2/2.4
working length 30 mm
bladeSNAP blade 2.8 mm diameter made of carbide with a TiAlN coating
Working speed 3,300 rpm
Cutting speed vc 25 m/min
Working feed 0.05 mm/rev

Customer benefit

The customer is completely satisfied with the high level of process reliability and the deburring quality. Previously, the common rails were deburred with a competitor tool. The blades designed specifically for tough materials have a service life of 500 bores and consequently 500 common rails. Thanks to the SNAP tool's reliable deburring, the process costs have been reduced.
