What is a CNC spring making machine? What is its working principle?

① What is a CNC spring making machine?

• Simply put, a CNC spring making machine is an automated machine controlled by a computer, specifically designed to produce springs and various wire products.
• In the past, making springs might require skilled craftsmen to operate manually, or rely on complex mechanical gears and cams. With a CNC spring making machine, the production process becomes as simple as printing a document on a printer: you only need to input the design parameters into the computer, and the machine will automatically transform a straight steel wire into springs of various shapes.

② How does a CNC spring making machine work?

• We can break down its working process into the following key steps for easier understanding:
• Computer "brain" issues commands: This is the core of the machine. The operator sets the size, number of turns, length, and shape of the spring on the computer screen. The computer converts this information into commands, precisely controlling when and how much each motor (usually servo motors) inside the machine moves.
• Automatic wire feeding: There is usually a large wire rack at the back of the machine, wound with steel wire. The wire feeding rollers inside the machine act like "little hands," tightly gripping the steel wire and continuously feeding it forward. The speed and length of the wire feeding are precisely controlled by the computer.
• Multi-directional "mechanical arms" bend and shape the wire: At the point where the steel wire is fed out, there are several movable tool holders or robotic arms. These "hands" will strike, squeeze, or bend the wire from different angles according to the instructions.
• If making helical springs, the wire will hit an inclined surface and naturally coil into a circle.
• If making complex shaped springs, multiple robotic arms will bend the wire into various angles or hooks, like kneading dough.
• Precise "one-cut" cutting: When a spring is completed according to the predetermined shape, the cutting tool on the machine will quickly pop out and cut the wire. The cut spring falls into the collection basket, and the production of the next spring immediately begins.

③ Why is this machine so powerful?

• Flexible and versatile: Traditional machines require half a day to adjust parts when changing the shape of a spring, while a CNC spring making machine only needs a program change on the computer to immediately switch to producing a different model.
• Tireless: As long as there is electricity and wire, it can produce continuously day and night, and the first spring and the ten-thousandth spring produced are almost identical, demonstrating exceptional precision.
• Handles complex shapes: Many springs used in modern equipment (such as automobiles or precision instruments) have very unusual shapes that are difficult to bend manually. However, this machine, through multi-axis linkage, can easily complete various complex spatial bending tasks.
