What is the working principle and the concrete function of wall grinding machine?
With stepless speed regulation system, it can easily adjust the grinding speed for grinding various parts. The closed loop feedback of electro pneumatic proportional valve is adopted
Pressure control, independent pressure control device. On the plate is set to slow down function, effectively prevent the broken water workpiece. Through a time relay and a grinding counter, the grinding time and the number of grinding cycles can be accurately set and controlled according to the processing requirements. When working, the pressure mode can be adjusted, and when the grinding set time or the lap speed is reached, the alarm is automatically stopped and semi-automatic operation is realized.
Variable speed control method of grinding machine, grinding process has three stages, namely the beginning stage, formal stage and end stage, beginning stage of abrasive speed rotation, the formal stage of abrasive rotating speed reduction, the end stage of tool rotation, which is characterized in that at the beginning of grinding, grinding speed controlled by slow acceleration from zero to quickly increase, when the abrasive speed rise to half the formal grinding speed, the acceleration of the change of the emergence of a turning point, control tools speed acceleration by the maximum value decreases from fast to slow, until the grinding speed reaches the grinding speed formal, abrasive speed acceleration to zero.
