Spring Manufacturing Process

Spring Winding

Coiling: The technician operating the machine sets it up to prepare it for the specific type of coil being made and feeds the wire into a set of rollers, which pulls the spring wire toward a set of guides.

Forming: This is done using a spring former or CNC spring former machine.

Bending: The machine works by feeding the wire into a set of rollers, which pull the wire to wire guides and push it to a moveable tooling head, controlled by the computer.

Heat Treating

Once a spring is formed, it typically needs to undergo a stress-relieving process, which will allow the spring to retain its memory. This memory allows the spring to bounce back when placed under stress. In the heat treating process, the spring manufacturer must heat treat the spring to a specific temperature for a specific amount of time. The temperature and time setting varies depending on the type and amount of wire involved.

Grinding

In the grinding process, the ends of the spring are ground flat, allowing it to stand up straight without wobbling when oriented vertically.Spring grinding is accomplished using a spring grinder. This grinding machine has two horizontal grinding wheels, spaced apart in a way that allows the length of the spring to enter between the wheels.

Coating and Finishing

As a final touch, springs are usually finished with some type of coating, plating or finishing process. In finishing processes, the spring's surface undergoes additional steps to help combat erosion, lend new properties to the spring or simply improve the spring's overall appearance.

FAQ

Q: What materials are used to make balls?

A: Chrome steel is the most common, but stainless steel, carbon steel, and special alloys are also used depending on the application.

Q: How round are precision balls?

A: High-grade balls can deviate from a perfect sphere by less than 0.13 microns, offering extreme precision for high-performance applications.

Q: What is the purpose of heat treating balls?

A: Heat treatment increases hardness and durability, allowing balls to withstand high loads and reduce wear in mechanical systems.

Q: What's the difference between grinding and lapping?

A: Grinding is a shaping process, while lapping is a polishing process that improves surface finish and achieves tight tolerances.

Q: What are the primary applications of springs?

A: Springs are commonly used in aerospace, automotive, oil & gas, and marine industries due to their excellent fatigue resistance, corrosion resistance, and ability to perform under high temperatures and harsh environments.

Q: How do you ensure the mechanical properties of your springs?
