“We make compression springs from Wire diameter 0.1 mm to 12.5 mm.”
The ends can be ground flat so that force is applied squarely to each end of the spring, reducing the tendency to buckle or to accommodate accurate seating requirements and a reduced solid height that may be imposed by particular applications.
How accurate designs compression springs:
- Compression springs are the easiest type to make. Can be made more rapidly and accurately than other types and should be used in preference to other types wherever possible.
- Avoid using open ends or open and ground ends. Such springs usually tangle when shipped. They also buckle when deflected.
- Use closed ends only and avoid grinding whenever possible, especially on light wire sizes under 0.60 mm or where a large spring index Om/d prevails such as 13 or larger. Grinding is a slow and expensive operation.
- Use conical springs when a short, solid height is needed and to reduce buckling.
- Avoid using conical, barrel-shaped, or other special shapes, where a standard helical spring could be used.
- Design springs with reasonably safe stress when compressed solid so that they may be adaptable to other installations.
7. Do not specify coiling right hand or left hand if it is not important. Specify right hand if it must be threaded onto a bolt. If a spring is used inside another, one spring should be wound left hand and the other right hand to avoid meshing of the coils.
