Lapping Guide Extension

Prior electrical lapping guides comprise a small layer of resistive material 10 which is removed by the lapping process until the resistance reaches a desired value.

Here, the resistive material 11 extends through the entire depth of material to be lapped to allow a constant monitoring of the lapping process. This is especially important when the lapping is of a relatively wide object, such that resistive material may be supplied on either side of the object to allow lapping to be balanced entirely across the object.
