CRANKSHAFT GRINDING

GRINDING PROCESS PRECISE IN A SINGLE SET-UP PENDULUM GRINDING 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 through the productive machine concept. Ideal dimensional stability and high process 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...

HIGHLIGHTS AND SPECIAL SOLUTIONS HIGHEST PRECISION FOR EVERY CRANKSHAFT HIGHLIGHTS • High process reliability due to complete grinding in a single set-up Optimum grinding quality due to automatic compensation of disturbance variables High dimensional stability due to in-process measuring system Flexible use for wide-ranging different cylinder numbers by CNC resetting Extreme smooth running due to directly driven grinding and work piece spindles Optimum support provided with self centering three point steady rests LARGE CRANKSHAFTS WORKPIECE SPECTRUM JUCRANK pendulum grinding machines take care...

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 menu...
