FINISHING METHOD Russian patent published in 2003 - IPC

FIELD: processes for superfinishing precise bodies of revolution of constructional steels. SUBSTANCE: method comprises steps of mounting abrasive blocks in tool head around axis inclined by acute angle relative to rotation axis of blank; imparting to tool head or to blank precession around center laid in symmetry axis of profile of abrasive blocks and spaced from plane of their symmetry by distance depending upon crossing angle of axes of blank and tool head, geometry dimensions of blank, grain size of abrasive blocks, precession frequency and speed of feeding abrasive blocks. EFFECT: enhanced efficiency of working due to periodical separation of abrasive blocks from worked surface, removing cuttings and slime from them and automatic sharpening of them, improved quality of working due to uniform taking off allowance along profile of blanks. 2 dwg, 1 ex
