A reproducible method for cutting a sparkplug was developed, consisting of:
- Clamping and positioning the sparkplug using a vertical clamping tool and a dedicated vise.
- Precision cutting with Secotom-50 to section the component exactly in the middle.
- A metal bonded diamond cutoff wheel with 0.6 mm thickness was used to achieve a minimum of mechanical damage and a very precise cut.
- A rotational speed of 2,200 rpm and a feed speed of 0.04 mm/s were used. A direct cut in the 85 mm length of the sparkplug was used, starting from the connector end towards the electrode end.
