SERDI S4.0 (Power)

Valve Seat & Guide Machining System

This highly versatile and powerful machine is suitable for work on cylinder heads ranging from motorcycles to large diesels, having a machining capacity of 14 to 120 mm.

The addition of air floated table bars simplifies and speeds set up particularly with large heads and the high torque, 0 - 1200 rpm spindle motor has infinitely variable speed control with digital read-out.

All this is combined with the patented air-float system which ensures perfect centering of each seat by aligning with its individual valve guide, not the machine bed. This even applies to the thinner valve stems below 4mm /0.16" diameter encountered in modern head design.

To maintain such high precision throughout the machining process, the spindle motors 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 and guide machines deliver results of unmatched accuracy.
