The NC servo feeder stands out as a highly reliable feeding machine widely acclaimed for its seamless installation, ease of adjustment, user-friendly operation, and exceptional feeding accuracy. Renowned for its stable performance, low failure rate, and simple maintenance, the NC servo feeder incorporates a cutting-edge electronic control system. This system includes a Yaskawa servo motor, Mitsubishi PLC, and Weilun touch screen. Although it comes at a higher cost compared to air feeders and roller feeders, its superior performance solidifies its popularity in the industry.

Key Features and Advantages of the NC Servo Feeder

High Feeding Accuracy

One of the most significant advantages of the NC servo feeder is its remarkable feeding accuracy. Under optimal conditions, it can achieve an accuracy level within ±0.02mm. This precision is crucial for ensuring high-quality output in manufacturing processes.

Advanced Electronic Control System

The feeder’s advanced electronic control system is designed for optimal performance. The integration of the Yaskawa servo motor, Mitsubishi PLC, and Weilun touch screen provides a seamless and efficient operation, enhancing overall productivity.

Ease of Use and Maintenance

The NC servo feeder is celebrated for its straightforward operation and low maintenance requirements. Its user-friendly design allows for easy adjustments, making it a preferred choice for operators seeking efficiency and reliability.

Common Causes of Inaccurate Feeding in NC Servo Feeders

Despite its high performance, the NC servo feeder can encounter feeding inaccuracies if not properly maintained or adjusted. Understanding and addressing the common causes of these issues can help maintain the feeder’s optimal performance.

Insufficient External Air Source Pressure

The NC servo feeder relies on cylinders for clamping and relaxing the material. Insufficient air source pressure can lead to malfunctioning cylinders, disrupting the normal feeding process. To resolve this, inspect the pressure gauge on the feeder’s three-point combination and ensure the external air source is adequate.

Inadequate Clamping Force of the Pressure Spring

If the pressure spring is not correctly adjusted, the material may slip between the rollers, resulting in inaccurate feeding. Increasing the clamping force of the pressure spring can mitigate this issue, ensuring consistent feeding accuracy.

Incorrect Feeding or Relaxing Time

Different molds require specific feeding and relaxing times based on their stamping processes. Often, users adjust only the feeding height after changing molds, neglecting to adjust the feeding and relaxing times. This can cause early or late feeding and relaxing. Adjusting these times accordingly can resolve the problem.

Excessive Feeding Speed

The NC servo feeder is not designed for high-speed operations due to the response time limitations of its electronic control system. If the stamping speed exceeds 200 times per minute, the feeder may not keep up. In such cases, switching to a high-speed feeding device like a roller feeder, clamp feeder, or gear feeder is recommended.

Presence of Oil or Foreign Objects in the Feeding Roller

Oil or foreign objects in the feeding roller can cause the material to slip, leading to feeding inaccuracies. Regularly cleaning the roller can prevent this issue, ensuring smooth and accurate feeding.

Maintaining Optimal Performance of Your NC Servo Feeder

To maintain the high performance and reliability of your NC servo feeder, regular maintenance and proper adjustments are essential. Here are some tips to help you keep your feeder in top condition:

Regular Inspection and Maintenance

Conduct regular inspections of the feeder’s components, including the electronic control system, pressure springs, and feeding rollers. Address any signs of wear and tear promptly to prevent potential issues.

Proper Adjustment of Feeding Parameters

Ensure that feeding parameters, such as feeding and relaxing times, are correctly adjusted based on the specific requirements of each mold. This will help maintain accurate and consistent feeding.

Cleaning and Lubrication

Keep the feeding rollers clean and free from oil and foreign objects. Regularly lubricate moving parts to ensure smooth operation and prevent unnecessary wear.

Monitoring Air Source Pressure

Regularly check the air source pressure and ensure it meets the feeder’s requirements. Address any issues with the external air source promptly to avoid disruptions in the feeding process.

Conclusion

The NC servo feeder is an indispensable tool in the manufacturing industry, known for its high accuracy, reliability, and ease of use. By understanding and addressing common causes of feeding inaccuracies, and maintaining regular inspections and adjustments, you can ensure your NC servo feeder operates at its best. Investing in proper maintenance and timely adjustments will help you maximize the performance and longevity of your feeder, ultimately enhancing your overall production efficiency.
