Surface layers damaged by cutting must be removed by grinding. Mounted specimens are ground with rotating discs of abrasive paper, for example wet silicon carbide paper.

 

The coarseness of the paper is indicated by a number: the number of grains of silicon carbide per square inch. So, for example, 180 grit paper is coarser than 1200 grit. The grinding procedure involves several stages, using a finer paper (higher number) each time. Each grinding stage removes the scratches from the previous coarser paper.

 

Iqualitrol provides complete grinding machine, from single disc (XGrind-319, XGrind-311) to double disc (XGrind-320, XGrind-316), from fixed speed to stepless speed, with or without polishing head (iGrind-826), polishing head used to grind mounted specimens.

 

This can be easily achieved by orienting the specimen perpendicular to the previous scratches. Between each grade the specimen is washed thoroughly with soapy water to prevent contamination from coarser grit present on the specimen surface. Typically, the finest grade of paper used is the 1200, and once the only scratches left on the specimen are from this grade.

 

The series of photos below shows the progression of the specimen when ground with progressively finer paper.
