Automatic Spring End Grinding Machine gives economical grinding of exact length of springs in large or small batches, with: ends parallel – axis and ends truly square – simultaneous grinding at both ends – use of both methods of grinding i.e. crush grinding or down feed grinding. The machines can be supplied in three different configurations. 

The Spring End Grinding Machine operates in two different modes.

In this process the distance between the two grinding wheels is pre-set. The springs are then fed through the loading plate between the grinding wheels, removing the excess material to the desired length. In case desired ground length is not achieved in single pass springs passed multiple times through wheels by bringing down the top wheel slightly for each pass.

In down-feed grinding top grinding wheel position is not fixed. It travels down from a pre-fixed starting position to an end position. End position is a desired ground height of the spring. The time & speed of down-word movement of the top grinding wheel is controlled. At end position springs are allowed to pass through the grinding wheels for some more time. This is known as Spark-out Time is for improving finishing of the springs. Machines are equipped with fully automatic down-feed grinding cycles controlled by a Programmable Logic Control & a Touch screen HMI.
