Electromechanical Balancing Systems

NN Combined Engineering Agencies has announced an alliance with Walter Dittel GmbH, a supplier of quality products for more than 40 years. Engineers in the grinding area from all over world appreciate the excellent performance of Walter Dittel products. Product highlights: electromechanical balancing systems, hydro balancing systems, sensors for reduction the imbalance of grinding wheels, acoustic emission sensors for process control of grinding applications. Dittel electro-mechanical balancing heads: after recording the imbalance of the grinding wheel by an acceleration pickup, two tungsten weights are driven by 2 motors in order to compensate the imbalance. Contact-less power and control transmission provides maintenance free operation. Acoustic signal emission is monitored during the complete dressing cycle of CBN wheels by using adjustable thresholds. When a continuous signal is detected, higher than a pre-determined limit, the wheel is perfectly dressed. The acoustic signal emission is monitored during the complete grinding cycle. If the level is higher than the pre-set threshold an emergency stop occurs.
