Complete machining of

truck camshafts proves its worth

Effective complete machining of DAF camshafts for commercial vehicles is based on the sophisticated interplay
between highperformance linear motors, ultra-precise in-process measuring systems and easily accessible
components. The Dutch truck manufacturer is extending its camshaft machining operations by adding the
modular concept on the new platform 6.

omfortable furnishings, long maintenance intervals and
excellent driving dynamics are the reasons for purchasing
Creliable DAF trucks. DAF praises its customers with the
highest level of efficiency, maximum driving comfort and a high
residual value.
The precisely machined camshafts ensure that the engines
of commercial vehicles function faultlessly and constantly
for a high mileage. With the JUCAM 6L, these are machined
efficiently and ultra precisely in a single clamping set-up. “The
camshafts are used in the six-cylinder diesel engine series of XF A matter of pure form
and CF models”, explains Wannes Bloemen, Senior Production The JUCAM machines impress with precise grinding results
