Two travel movements, (B) the travel of the spindle sheath and (C) the radial travel of the tool holder carriage, are achieved owing to servo motors and high-precision satellite roller screws.

These two movements are numerically controlled in order to accurately reproduce a profile saved in a database and available at all times. An unlimited number of simple or complex profiles are therefore available and achievable with one single standard tool available anywhere in the world.

A simplification to the extreme of the tooling required and the possibility to carry out the most complex profiles are the primary benefits of the FIXED-TURNING^® and of the NEWEN numerical control.

Over with constraints and countless limitations of the form tool (3 angle cutters), the numerical control and the FIXED-TURNING^® yield the highest precision, total flexibility, independence and the recognition of a high professional level.

An electronic linear gauge (E) in contact with the gasket plane of the cylinder head allows to adjust valve seat depth within 0.01mm (.00039") and to endlessly repeat machining operations within the same tolerance.

A single point cutter travels both in height and in diameter (B, C), at the same time. The computer pilots the tool according to a requested shape and the single point, as with a lathe, machines the shape in successive passes.

The cutting efforts are so light that the spindle and the tool do not flex. The resulting shapes are geometrically perfect and the surface finish is excellent.

Forget chatter marks, ovals, seats that do not seal, irregular depths and other defects that would have a negative effect on the engine functioning.
