Brief Introduction:

iqualitrol XGrind-307 pre-grinding machine is a table style machine with double discs, which is used for rough grinding, half finished grinding and fine grinding operation for metallographic sample.

It is necessary for users making metallographic sample. The cooling system can keep samples metallographic organization in good condition during grinding and polishing.

The machine can be operated by two operators simultaneously. It is convenient and on the safe side .It is an ideal option for the lab of factories, science and research institutions and universities.

Technical Parameters:

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.

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.
