The grinding machine uses 2 upright grinding wheels, the springs are set on the feeding plate. Feeding speed of the upper grinding wheel is adjustable, in continuous and stepping feeding, allows the spring reach a preset height, obtain a maxi grinding capacity according to the pressure used. This machine has the function of self-compensation, self reset, alarm. Using man-machine interaction, we can make programming via the screen which makes it easy to use and increase the productivity.
