Description

Fully automatic polishing machine considering convenience}

The present invention can automatically and uniformly grind the outer circumferential surface of the abrasive object uniformly through the grinding unit moving in the front and rear directions of the plate-shaped object as well as the rod-shaped object. It relates to a fully automatic grinder considering the convenience of deriving reliable data without fear of change.

Specimen polishing is an essential process for physical property testing that acquires material properties before product development, and depending on the presence or absence of polishing, stress concentration occurs due to the notch effect on the surface, resulting in actual material properties. There is a possibility of obtaining unreliable data and other unreliable data, so it is necessary to provide a specimen grinder with reliability and expertise to secure reliable data.

In general, specimens processed into standard specimens through machining are divided into round bar and plate type, and grinding is performed according to the condition of the specimen before testing.

In the case of metal specimens, the gage length and the wooden part where the width of the clamping part decreases are specified as R values in the test standard.

Discontinuity points and notches are generated while performing this R processing, which may have an inappropriate factor on the results of the physical properties of the specimen.

However, there is a high possibility that the aspect of the polishing operation result of the specimen may vary depending on the skill level of the operator, and there is a high possibility that reliable data derivation is hindered.

In order to solve this problem, recently, a metal surface polishing device capable of automatically polishing metal specimens as well as reducing frictional heat generated during specimen polishing has been proposed through Domestic Patent Publication No. 10-1701717. there is a bar
