SERDI - Leaders in valve seat machinery

All SERDI valve seat machines feature their patented automatic air-float system which ensures perfect centring of each seat by aligning with its individual valve guide, not the machine bed. This even applies with the thinner valve stems below 4mm / 0.16" diameter encountered in modern cylinder head design. The operator has only to position the solid carbide shank pilot into the valve guide after which the combination of flat and spherical air cushions allows the entire workhead and spindle to free-float. It automatically aligns with the valve guide, regardless of any misalignment or angular deflection of the guide due to wear or poor installation. This crucial process requiring the minimum of operator in-put takes only a matter of seconds and upon completion, the workhead is automatically fixed for machining to commence.

To maintain such high precision throughout the machining process, the spindle motor is integral with the drive shaft thereby providing minimal workhead inertia. These features, combined with the use of constant torque motors with Siemens control, all ensure SERDI valve seat & guide machines deliver results of unmatched accuracy.
