In the world of engineering and manufacturing, precision is key, and one important component that plays a significant role in achieving this precision is springs. Springs are widely used in various industries due to their unique properties, providing elasticity and storing mechanical energy. With advancements in technology, Computer Numerical Control (CNC) machining has revolutionized the production process of different types of springs, enabling optimal performance and customization.

1. Compression Springs:
Compression springs are perhaps the most commonly recognized type of spring. As the name suggests, these springs compress under an applied force and return to their original length once the force is removed. In CNC machining, producing compression springs involves several key steps. It begins with designing the spring's helix profile, followed by programming the CNC machine to precisely control the coiling process. The machine then forms the wire into the desired shape while taking into account critical factors such as pitch, diameter, and number of coils.

2. Torsion Springs:
Torsion springs operate by twisting or rotating along their axis when subjected to torque. These springs find applications in various systems where rotational force needs to be controlled or accumulated. Creating torsion springs through CNC machining requires expert knowledge and precise programming. The CNC machine is programmed to accurately wind the wire around mandrels at specific angles and distances between coils, ensuring consistent torque characteristics for each designed application.

3. Extension Springs:
Extension springs differ from compression springs as they extend rather than compress under external forces. They usually consist of tightly wound coils with hooks on either end for attachment purposes. To manufacture extension springs using CNC machining, specialized machines are utilized to precisely form the coils according to design specifications. Accurate tension levels and hook formations are essential to achieve optimal performance.

4. Constant Force Springs:
Constant force springs provide uniform force throughout their entire deflection range. These springs come in various shapes like spiral, ribbon, and strip. CNC machining techniques are employed to cut, form, or roll the spring material into a specific shape depending on its intended application. The precision offered by CNC machines ensures consistent force output, making constant force springs suitable for applications that require smooth, reliable motion.

5. Belleville Washers:
Belleville washers, also known as disc springs, provide high load capacity within minimal axial space. These conical-shaped springs have been widely used in industries where weight and space limitations are critical factors. With CNC machining, these washers can be manufactured with precise thickness, outer diameter, and clearance. This allows for customization according to desired load characteristics while maximizing efficiency and compactness.


From compression to extension springs, torsion springs to constant force springs, and belleville washers, the diverse range of springs created through CNC machining offers immense versatility in engineering applications. Harnessing the power of computer control and automation, CNC machines ensure the accurate production of springs with customized specifications and excellent performance capabilities. As technology continues to advance, CNC machining will play an increasingly crucial role in meeting the demands for innovation and precision across different industries. CNC Milling
