A reproducible method for cutting a spark plug was developed consisting of:
- Clamping and positioning the spark plug using a vertical clamping tool and a dedicated vise.
- Precision cutting with Secotom-50 to section the component excately in the middle.
- An metal bonded diamond cut off wheel with 0,6 mm thickness was used to acheive a minimum of mechanical damage and a very precise cut
- Rotational speed of 2200 rpm and feed speed of 0,04 mm/s was used. Direct cut in the 85 mm length of the spark plug was used starting form the connector end towards the electrode end.
