The next five years should produce a more reliable 'active' force sensing technology." Advancements in robot controllers facilitates better force control for grinding, deburring and finishing applications says Morris. "Highspeed force control is one of the biggest developments in the past five years.
The vibrations caused by the unbalanced grinding wheels are detected and processed by the vibration sensor connected with the control unit. MPM balancers can therefore balance fully automatic as required at operating rpm – without having to remove the grinding wheel from the machine. MPM balancers are also available with AEGAP/Crash/Dress ...
