dc.description Patent / patent application Nr. MD 622 from 30.04.2013. Domain: Industrial equipment and units. en_US
dc.description.abstract Invenţia se referă la tehnologia construcţiei de maşini, în special la prelucrarea pieselor din metal cu forme geometrice greu prelucrabile prin aşchiere. Scula abrazivă este executată în formă de disc şi conţine sectoare abrazive cu granulaţie mare (1) şi granulaţie mică (2), care în pereche sunt divizate de un sector abraziv cu o duritate mai mică (3) decât duritatea sectoarelor abrazive cu granulaţie mare (1) şi mică (2). Sectoarele abrazive sunt unite între ele, spre centrul sculei, printr-un cerc abraziv cu duritate mai mică, iar lungimile arcurilor de circumferinţă ale sectoarelor abrazive cu granulaţie mare (1) şi mică(2) sunt egale şi de două ori mai mari decât lungimea arcului de circumferinţă al sectorului abraziv cu duritate mai mică (3). en_US
dc.description.abstract The invention relates to the mechanical engineering technology, in particular to the machining of metal parts with geometric shapes hard-to-machine by cutting. The abrasive tool is made in the form of a disk and contains coarse- grained (1) an fine-grained (2) abrasive sections, which are pairwise divided by an abrasive section with a lower hardness (3) than the hardness of the coarse-grained (1) and fine-grained (2) abrasive sections. The abrasive sections are interconnected, to the center of the tool, by means of an abrasive circle with a lower hardness, and the lengths of the arcs of circles of the coarse-grained (1) and fine-grained (2) abrasive sections are equal and twice greater than the length of the arc of circle of the abrasive section with a lower hardness (3). The fine-grained abrasive section (2) is made of abrasive flour grain, the coarse- grained section (1) − of abrasive grain, and the abrasive section with lower hardness (3) − of abrasive powder. The hardness of abrasives is selected depending on the hardness of the workpiece material. en_US
