1,Single plate
SLM series CNC spring end grinding machine is mainly used for grinding the double surfaces of the compression springs(including cylindrical springs, conical springs and double conical springs).
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.
2,Double plate
SLM series CNC spring end grinding machine with double plate is designed on the basis of single plate machine, by adding another plate. It uses the air cylinder to realize the cyclic conversion and positioning of the 2 plates. There are 2 options: manual plate changing and automatic plate changing. The advantage: grinding and spring loading and unloading at the same time.
