YLSK series CNC spring end grinding machine and grinders are mainly used for grinding the double sides of the compression springs(including cylindrical springs,conical springs and double conical springs).
The grinding machine uses 2 upright grinding wheelsthe springs are set on the feeding plate feeding speed of the upper grinding wheel is adjustablein continuous and stepping feeding allowing the spring reach a preset height,obtain a maxi grinding capacity according to the pressure used. This machine has the function of self-compensation,selfresetalarm.Using man-machine interaction, we can make programming via the screen which makes it easy to use and increase the productivity.
