Abrasive machining of crankshaft crankpins comprises machining device comprising support translational on frame and abrasive application means which can move angularly around support pivoting axis

摘要

The machining machine for a crankpin (6) on a crankshaft (1) has a machining device (7) comprising a support (8) able to move translationally on a frame (4). Abrasive application means (20) can move angularly around a pivoting axis (12) on the support. There are means for the angular positioning of the abrasive application means and translational positioning of the support during rotation of the crankshaft around its axis.
