They are designed to allow axial compression in almost any spring orientation. Ends that are ground perpendicular to the spring axis promote axial compression. However, grinding of spring ends should be avoided whenever possible for wire diameters below 1.00 mm or for coil ratios greater than 15. Since spring end grinding is a cost-intensive process, it should be avoided for economic reasons if feasible. The same applies to the application of an inner and\/or outer chamfer.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h3 class=\"wp-block-heading has-white-color has-text-color has-background has-link-color wp-elements-38765ec05c7345d7f08dbc828929df5d\" style=\"background-color:#009ee2\">Surface<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Compression springs made from spring steel EN 10270-1 are lightly oiled after heat treatment.
