DEVICE FOR HOLE FINISHING Russian patent published in 1996 - IPC

FIELD: machine-tool manufacture. SUBSTANCE: device is equipped with flexible member fastened in stationary housing from the side of spindle 2 with detail or tool and made as two cylindrical bars 11 whose free ends are hard-mounted with hull 8 in which detail 7 is fixed. Details 6 and 7 in pair are secured in clamping devices. Contacting of details 6 and 7 takes place at blow of definite intensity. In the process of spindle rotation during its throbbing spindle 2 deviates for a certain angle from initial position. In this case flexible bars 11 deviate together with hull 8 and detail 7. As a result misalignment of axes of details 6 and 7 is practically absent. EFFECT: enhanced efficiency of processing due to increase in kinetic energy of collision of tool and detail. 2 dwg
