KHI Technology engineers have devised a method to manufacture springs with concentricity’s in the single digits. Using the latest CNC coiling equipment and the latest vision inspection equipment we are able to offer more precise and repeatable spring concentricity’s, inside diameters and outside diameters. We are also able to control end closings for large coil diameters in a conical spring using specialized CNC servo motors. Contact our sales team for any projects you are looking help with.
