Springs are mechanical devices that store energy and release it when subjected to external forces or loads. These versatile components find extensive use in numerous industries, including automotive, aerospace, robotics, and of course, CNC machining. In this article, we will delve into the various types of springs commonly employed in CNC machining processes and how they contribute to the efficiency and precision of such operations.

1. Compression Springs:
Compression springs are perhaps the most widely recognized type of spring used in CNC machining applications. As their name suggests, these springs compress under force and expand back to their original length upon release. They are essential for absorbing shocks and vibrations, maintaining consistent pressure, and ensuring precise positioning within machinery during cutting, drilling, or shaping tasks.

Producing Compression Springs:

To manufacture compression springs, a CNC machine is employed with specialized tooling capable of coiling different kinds of wire, such as stainless steel or high carbon steel, into uniform and tightly-packed helical shapes. The desirable characteristics of compression springs can be achieved by manipulating parameters like wire diameter, coil pitch, and number of active coils based on specific requirements.

2. Torsion Springs:
Torsion springs, also known as helical springs, operate differently from compression springs. Instead of resisting axial forces, torsion springs generate rotational movement in response to torque applied around an axis. This characteristic makes them ideal for applications involving hinges, levers, and balance mechanisms in CNC machines.

Producing Torsion Springs:

CNC machining facilitates efficient production of torsion springs by employing computer-controlled lathes or milling machines equipped with the necessary tools to shape wire or bar stock materials into precisely calculated helical forms. Parameters, such as the number of turns, diameter, and wire material, influence the strength, resistance, and overall performance of torsion springs, making customization readily achievable.

3. Extension Springs:
Extension springs, as the name implies, extend when stretched and store energy in the process. They are commonly found in CNC machines to counterbalance or support moving parts, such as tool holders, spindle heads, or z-axis assemblies, ensuring stability and precise control during machining operations.

Producing Extension Springs:

The production of extension springs involves precision cutting, bending, and shaping techniques enabled by CNC machines. The desired length, wire thickness, and number of coils dictate the specifications required for producing extension springs tailored to specific load-bearing applications within CNC machining setups.

4. Constant Force Springs:
Constant force springs provide a steady output force throughout their entire deflection range, making them invaluable in applications requiring constant tension or linear motion. In CNC machining, they find use in retractable cable management systems, belt-driven mechanisms, and other intricate designs where controlled force is necessary.

Producing Constant Force Springs:

To produce constant force springs, CNC technology allows accurate fabrication by coiling flat strip materials onto a drum or spool. By adjusting parameters like width, material selection, and thickness, manufacturers can create customized constant force springs that meet project-specific requirements within CNC machining environments.


Springs play an indispensable role in CNC machining, providing structural reliability, precision movement, and operational safety. From compression springs absorbing shocks to torsion springs facilitating rotational motion, these vital components enhance the efficiency and accuracy of CNC machines across diverse industries. Understanding the different kinds of springs and their production processes empowers manufacturers to select the most suitable options for optimizing performance and achieving exceptional results in their CNC machining endeavors.
