The camless spring machine is an advanced and innovative piece of equipment in the spring manufacturing industry, which has revolutionized traditional spring production with its cam-free design and full servo control technology. Unlike conventional cam spring machines, it abandons the traditional cam mechanism and adopts independently controlled multi-axis servo motors, making it more flexible, precise and efficient in production.
Equipped with 12 to 14 axes as standard (expandable to 21 axes), the machine is driven by high-precision servo motors, usually imported from Japan or other well-known brands, ensuring stable and accurate operation. It adopts an intelligent CNC control system, often with a user-friendly interface supporting both Chinese and English, enabling easy parameter setting, program editing and operation even for new operators. The machine can process wire diameters ranging from 0.3mm to 8.0mm, with a maximum production rate of up to 100 pieces per minute, meeting the needs of mass production and small-batch customization alike.
One of its core advantages is the fast setup and changeover speed, which is more than 50% faster than traditional cam machines, greatly reducing downtime and improving production efficiency. It can produce various types of springs, including compression springs, tension springs, torsion springs, scroll springs, tower springs and special-shaped springs, widely used in automotive, aviation, railway, furniture, medical equipment and electronic industries.
With features such as high forming precision, low maintenance cost, low noise and safe operation, the camless spring machine has become a preferred choice for modern spring manufacturers. It not only ensures consistent product quality but also enhances production flexibility, helping enterprises adapt to the ever-changing market demands and gain competitive advantages in the industry.
- Check the tightness of each part: Check the bolts, nuts and other connecting parts of the machine body, servo motor, wire feeding mechanism and other components, and tighten them if they are loose; check the connection of the signal line and power cord, and reinsert them if they are loose.
- Inspect the servo system: Check the heat dissipation of the servo motor and driver, clean the dust on the surface of the heat sink to ensure good heat dissipation; check the servo motor bearing, add lubricating grease if necessary.
- Maintain the air circuit system: Drain the water in the air compressor and air filter, clean the filter element; check the air pipe for air leakage, replace the damaged air pipe or joint if necessary.
- Calibrate the precision: Calibrate the positioning precision of each servo axis and the wire feeding precision, adjust the parameters if there is any deviation, and ensure that the processing precision meets the requirements.
- Inspect the fixture and mold: Check the wear of the forming fixture and mold, repair or replace them if they are seriously worn; clean the mold and apply anti-rust oil to prevent rust.
- Disassemble and inspect key parts: Disassemble the wire feeding mechanism, forming mechanism, servo motor and other key parts, clean them thoroughly, check for wear, deformation or damage, and replace the worn parts (such as ball screws, linear guides, bearings).
- Overhaul the electrical system: Open the control cabinet, clean the dust inside the cabinet, check the aging of the wires, relays, contactors and other components, and replace them if necessary; check the CNC system, update the system software if necessary.
- Calibrate the overall precision: Calibrate the overall forming precision of the machine, adjust the level of the machine body, and ensure that the processing error is within the allowable range.
- Anti-rust treatment: Apply anti-rust oil to the surface of the machine body, metal components and mold to prevent rust during long-term storage or use; check the paint on the machine surface, touch up the paint if it is peeled off.

Q What is a camless spring machine and how does it differ from a traditional cam spring machine?A camless spring machine uses full servo drive technology instead of a traditional cam mechanism. Each forming axis is independently controlled by a servo motor, allowing flexible forming trajectory adjustment without the need to replace cam pieces when switching product models. This results in greater flexibility, higher precision, and faster changeover compared to conventional cam spring machines.
-
Q What wire diameters can the SMS-1245WZ camless spring machine process?The SMS-1245WZ model is designed to process wire diameters ranging from Φ1.2mm to Φ4.5mm, with a maximum outer spring diameter of Φ120mm. It is suitable for a wide range of wire materials including steel wire, copper wire, and stainless steel wire.
-
Q What types of springs can be produced by the SMS-1245WZ camless spring machine?The machine is capable of producing a wide variety of spring types, including compression springs, tension springs, torsion springs, scroll springs, tower springs, and special-shaped springs. It is widely applied in industries such as automotive, aviation, railway, furniture, medical equipment, and electronics.
-
Q How quickly can the SMS-1245WZ switch between different product models?One of the key advantages of the camless design is fast model switching. There is no need to disassemble or replace cam pieces — simply call the pre-stored product program or modify parameters, and the changeover can be completed within 3 to 5 minutes. This is more than 50% faster than traditional cam machines, significantly reducing downtime.
-
Q What are the power supply requirements for the SMS-1245WZ?The SMS-1245WZ requires a 3-phase 380V AC power supply at 50/60Hz. Please ensure your facility meets this electrical specification before installation. The machine is equipped with comprehensive protection functions including overcurrent, overvoltage, overheating, and emergency stop to ensure safe operation.
-
Q How often does the SMS-1245WZ camless spring machine require maintenance?Regular maintenance should be performed once a month, including checking part tightness, inspecting the servo system, maintaining the air circuit system, calibrating precision, and inspecting fixtures and molds. A comprehensive annual maintenance is also recommended, covering disassembly and inspection of key parts, electrical system overhaul, overall precision calibration, and anti-rust treatment of all metal components.
