CRANKSHAFT GRINDING

GRINDING PROCESS PRECISE IN A SINGLE SET-UP PENDULUM GRINDING The pendulum grinding method enables crankshafts to be rough and finish ground in a single clamping set-up. The crankshaft rotates around its central axis and the grinding wheel follows the circular motion of the pin bearing by interpolation of the workpiece spindle (C axis) with the grinding spindle (X axis). AXIALLY PARALLEL The JUCRANK non-cylindrical grinding machine accomplishes all grinding tasks on crankshafts. Maximum accuracy and quick cycle times are achieved through oscillation grinding in a single clamping set-up and...

EQUIPMENT AND OPTIONS LEARNING FUNCTION CONTROL SYSTEM The JUCRANK's control system comes with automatic compensation of runout and disturbing variables such as temperature influences, grinding allowance fluctuations or material changes. Even minimal deviations between the target and actual position of the grinding wheel are automatically corrected. The Erwin Junker Operator Panel was specifically developed to control grinding machines. All machine components are controlled using the operator panel – irrespective of the series and the used control system. The identical structure, intuitive...
