Grinding machine for the grinding of spring ends

A grinding machine for grinding an end of a spring, the machine comprising a fixed spring mounting, which is fixable in a known position in the machine, for a spring or springs and a grinding surface secured to a support structure and arranged within the support structure to relatively oscillate to and fro along a guided oscillation path or cycle across one end of the spring mounting with the grinding surface for continuous contact in use with at least one end of one spring and means to advance the continuous contact to flatten each end of the spring or springs to the grinding surface, wherein the support structure comprises a first housing or cabinet surrounding the grinding surface and the whole or a chassis part of the first housing displaced to provide relative oscillation to and fro along the oscillation path or cycle.
