Q1. What are the advantages of CNC spring forming machines?

A. CNC spring forming machines are suitable for producing various springs and wire forms. They can improve dimensional stability, angle consistency, and the mass-production capability of complex shapes. They are especially useful for parts with multiple bends, multiple angles, or high repeatability requirements.

Q2. Why are springs heat-treated?

A. Springs may contain internal stress after forming. Heat treatment can stabilize elasticity, reduce the risk of deformation, improve dimensional stability, and support service life. Different materials and products require different heat-treatment conditions.

Q3. What is the purpose of a continuous tempering furnace?

A. A continuous tempering furnace is suitable for heat treatment of springs in mass production. It allows products to pass through heating and tempering under stable conditions, improving consistency across production batches.

Q4. When is grinding required?

A. Compression springs often require end grinding when flat contact surfaces, stable standing, or even loading are needed. Grinding improves the contact surface but adds process steps and cost.

Q5. When is tooling or a fixture required?

A. Tooling or fixtures are usually required when a product has a special shape, multiple angles, tight dimensional tolerances, larger quantities, or requires stable mass production. Fixtures can improve consistency but may involve a one-time cost and additional development time.
