Springs are essential mechanical components that store potential energy and release it when subjected to external forces or loads. These versatile devices find applications in various industries, including automotive, aerospace, electronics, and manufacturing. In this article, we will explore different types of springs, their characteristics, and the processes involved in producing these vital components using CNC machining technology.

1. Compression Springs:
Compression springs are the most common type and are widely used in numerous applications. They work by resisting compressive forces applied axially along their length. Compression springs come in a range of shapes, sizes, and materials, allowing them to be customized for specific requirements. The production process involves precision CNC machining to ensure accurate dimensions and consistent spring rates.

2. Torsion Springs:
Torsion springs are designed to resist rotational forces or torque around an axis. They store and release energy through twisting motion. These springs often find applications in clipboards, clothespins, garage doors, and various other products that require rotary force. CNC machining techniques enable the precise fabrication of torsion springs with controlled angles and proper alignment between coils.

3. Extension Springs:
Extension springs, also known as tension springs, absorb and store energy when stretched. This type of spring is commonly seen in household items like trampolines, garage door systems, and industrial equipment. CNC machining ensures uniform wire diameter, pitch, and overall dimensions during the production process, which are crucial for achieving accurate extension properties.

4. Wave Springs:
Wave springs are innovative alternatives to traditional coil springs due to their compact design and reduced material usage. They have a wavy profile and generate substantial linear force while maintaining small working heights. These springs excel in space-limited applications such as automobiles, medical devices, and valves. CNC machining plays a crucial role in precisely forming the complex wave patterns and dimensions required for optimal performance.

5. Constant Force Springs:
Constant force springs deliver a continuous and uniform force throughout their deflection range. These springs find applications in retractable seat belts, window blinds, tape measures, and other devices requiring consistent force over large extensions. The intricate CNC machining process ensures precise fabrication of these springs by maintaining a constant pitch with highly repetitive coils.

6. Belleville Washers or Disc Springs:
Belleville washers, commonly referred to as disc springs, are conical-shaped disks used to apply controlled pressures. Their stack arrangement allows for high load capacities while maintaining low spring rates. These springs are widely utilized in valve systems, ball bearings, electrical contacts, and safety valves. CNC machining enables accurate production of the angular designs and tight tolerances required for optimal performance.


Springs are remarkably versatile mechanical components that serve essential roles in numerous industries. By utilizing CNC machining technology, manufacturers can produce different types of springs with precision, consistency, and conformity to strict specifications. Whether it be compression springs, torsion springs, extension springs, wave springs, constant force springs, or disc springs, each variety has its unique properties and applications. Understanding the characteristics and manufacturing processes behind these springs is crucial for producing reliable and high-performance products in various sectors. CNC Milling CNC Machining
