MACHINE AND METHOD FOR MACHINING LARGE CRANKSHAFTS.

摘要

The invention relates to a machine and method for machining large crankshafts, enabling the simple and reliable synchronisation of the rotational movement of the crankshaft (14) at all of the points thereof. The machine includes: a machining tool (1) configured to move along the length of at least one guide (2) between a first end supporting element (3) and a second end supporting element (4), an electronic angular position sensor (6) located on a first rotation shaft (7) of the first end supporting element (3), and a second electronic angular position sensor (8) located on a second rotation shaft (9) of the second end supporting element (4), such that the rotational movement of the first end supporting element (3) is electronically synchronised with the rotational movement of the second end supporting element (4) at all times during the machining of the crankshaft (14).
