Traditional measuring means are not sufficient to precisely control valve seats and valve guides machined with NEWEN® FIXED-TURNING® machines.

NEWEN® has equipped itself with a TALYROND 365XL control machine, especially conceived and dedicated to the measurement of shapes, coaxialities, surface finish...

This machine whose resolution is 1/100 of a micron allows to automatically control all geometric parameters that define the quality of a guide and of a valve seat: circularity, concentricity, run out, cylindricity, segment linearity, angles, surface finish... The control reports and graphs resulting from the test are indisputably recognized by the control departments of the most prestigious OEMs.

NEWEN is continuously testing the work produced by the machines it manufactures and demonstrates quality with actual measures.
