Secondary Spring & Wire Form Operations

Grind
The ends of some compression springs are ground flat to improve squareness and reduce buckling during operation.  We grind compression springs (ground ends) with wire diameters as low as .008” and up to .148”.  Squared and ground springs are normally supplied with a bearing surface of 270 degrees to 330 degrees.  Additional grinding results in thin sections.

Compression Spring Grinding


Thread
Your application may call for the end of your wire form to be threaded, so a knob or bolt can be assembled to it.

Wire Form Thread


Chamfer
Some wire forms have one or both ends chamfered to remove any sharp edges or to make the ends tapered.

Swage
Some wire forms have a section squeezed to create a protuberance from the wire.

Drill
Some wire forms require a hole drilled through.  Some holes require a counter-bore.
