iqualitrol Grinding and Polishing Machine XGrind-306

Brief Introduction:

The iqualitrol pre-grinding machine is table style with single disc, which used for rough grinding, half finished grinding and fine grinding operation for metallographic sample.

XGrind-306 is necessary for users making metallographic sample. The cooling system can keep samples metallographic organization in good condition during grinding and polishing.

XGrind-306 is convenient and on the safe side, an ideal option for lab, factories, science and research institutions and universities.

Technical Specifications:

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.

After a metallographic sample has been mounted, grinding and polishing creates a flat and even surface. Any potential residue from the mounting process or damage from the sectioning process are ground off to expose the actual microstructure of the sample. Polishing removes abrasions from the previous steps to provide a smooth surface.

iqualitrol grinding and polishing instruments ensure that metallographic instruments provide a reliably clean sample that will be ready for further analysis.
