Common rail
In the low-pressure range, diesel fuel distribution systems also require cleanly deburred bores.
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.
| Workpiece | Common Rail |
| Low pressure bore | 2.4 mm |
| Main bore | 9.0 mm |
| max. Deburring diameter | 2.8 mm |
| Material | forged case-hardened steel (1,000-1,300 N/mm²) |
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.
| Tool | SNAP 2/2.4 |
| working length | 30 mm |
| blade | SNAP 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 |
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.
