Machining with FIXED-TURNING® guarantees that the valve seat, the valve guide and the cam-bucket bore housing shall have one same axis, shall be perfectly aligned, and tat the parts shall be able to move at the highest speeds without being subjected to frictions and parasitic brakings that would render the functioning of the engine at high RPM impossible, with corollary a rapid wear and an obvious risk of mechanical incidents.

The machining of the guides, of the valve seats and of the cam-bucket bore housings with FIXED-TURNING® guarantees an ultra rapid functioning of the engine, in conjunction with the components used, Titanium alloy valves, special springs, special valve seats…without risk of air-tightness defect, parasitage in the functioning by frictions and oil film ruptures, The panicking of valves ,unable to follow elevated regimes, shall also be avoided.

The NEWEN FIXED-TURNING® is a machining concept which has been developed to bring back machining defects within values expressed in microns and no longer in hundredths of a millimeter.
