Springs are a fascinating mechanical component widely used in various industries for their ability to store energy and provide resistance. With their diverse range of shapes, sizes, and materials, springs have become an integral part of numerous applications, ranging from everyday objects to complex machinery. In this article, we will delve into different kinds of springs and explore their unique characteristics and uses.

1. Compression Springs:
Compression springs are one of the most common types of springs used today. They are designed to resist compressive forces and return to their original length when the load is removed. These springs find applications in automotive suspensions, industrial equipment, mattresses, and even ballpoint pens. The manufacturing process involves CNC machining performed on coiled wire, which is shaped into a helical coil with evenly spaced gaps between each turn.

2. Extension Springs:
Unlike compression springs, extension springs are designed to resist tensile forces while being stretched along their axis. They possess hooks or loops at each end to attach to other components. Extension springs can be found in garage doors, trampolines, farm machinery, and various industrial applications. To produce extension springs with precise dimensions, CNC machining plays a significant role by bending the wire correctly to create the desired design geometry.

3. Torsion Springs:
Torsion springs operate differently from compression and extension springs as they generate rotational force. When twisted or rotated around its axis, these springs exert torque in the opposite direction, providing stability and equilibrium. Common applications of torsion springs include hinges, mouse traps, clothespins, and electric motor brushes. CNC machining allows for accurate production of torsion springs by shaping the wire into tightly wound coils with arms extending symmetrically from the central axis.

4. Constant Force Springs:
Constant force springs provide a near-constant force throughout their deflection cycle. As a result, they are well-suited for applications that require smooth and consistent movement, such as tape measures, window blinds, and conveyor systems. CNC machining plays an integral part in producing these springs, ensuring precise shaping of the strip into a tightly wound coil with an attached arbor or drum.

5. Belleville Springs:
Belleville springs, also known as disc springs or conical washers, are conically shaped discs designed to compensate for thermal expansion, bolt creep, and joint relaxation. They utilize their spring-like properties to exert force when compressed axially. These springs find extensive usage in valves, clutches, electrical switches, and flange joints. CNC machining enables accurate production of belleville springs by shaping flat discs into precisely formed cones.


Springs play a vital role in the functioning of countless products and equipment across various industries. From compression and extension springs to torsion and constant force springs, each type possesses unique characteristics catered to specific applications. The use of CNC machining in the manufacturing process ensures precision, accuracy, and consistency in producing springs tailored to desired specifications. As technology continues to advance, we can expect further innovations in spring design and increased utilization across numerous fields. CNC Milling
