SLM Series of CNC spring end grinding machine is mainly used in synchronized spring of double surface of compression spring,including cylindric spring,conical spring and double conical spring.
The machine adopts two vertical grinding wheels to grind springs put on feeding plate which pass through two grinding wheels. Feeding speed of upper grinding wheel can be adjusted. Through manual feeding mode or automatic feeding mode spring can get the preset height,you can obtain the greatest capacity of grinding according to the pressure. The machine has automatic compensation,automatic reset,giving alarm function,through man-machine dialogue manner and programmed on the computer screen,convenient operation and high production efficiency,it is ideal equipment for mass springs double surface grinding.
