Zusammenfassung: | 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) and 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.
Inventia se refera la tehnologia constructiei de masini, în special la prelucrarea pieselor din metal cu forme geometrice greu prelucrabile prin aschiere.Scula abraziva este executata în forma de disc si contine sectoare abrazive cu granulatie mare (1) si granulatie mica (2), care în pereche sunt divizate de un sector abraziv cu o duritate mai mica (3) decât duritatea sectoarelor abrazive cu granulatie mare (1) si mica (2). Sectoarele abrazive sunt unite între ele, spre centrul sculei, printr-un cerc abraziv cu duritate mai mica, iar lungimile arcurilor de circumferinta ale sectoarelor abrazive cu granulatie mare (1) si mica (2) sunt egale si de doua ori mai mari decât lungimea arcului de circumferinta al sectorului abraziv cu duritate mai mica (3). Sectorul abraziv cu granulatie mica (2) este executat din micropulbere abraziva, sectorul abraziv cu granulatie mare (1) - din granule abrazive, si sectorul abraziv cu duritate mai mica (3) - din pulbere abraziva. Duritatea abrazivilor este selectata în functie de duritatea materialului piesei prelucrate. |
