The Single Wheel Lapping and Polishing Technique

Since 1960, when the author started to work in the lapping business, until
present time (2005) the lapping technique has experienced an enormous
improvement in quality.

At that time, a simple single wheel lapping machine equipped with the
ingenious dressing device (dressing by the very friction of the dressing rings) proved a huge success whereas nowadays highest precision is requested (picture 1).

New technologies, such as the double wheel flat honing technique (developed by the author in 1980), have resulted in the so-called “clean lapping”, offering high stock removal and high precision.
