How to improve the service life of CNC bending machine molds

CNC bending machine molds play a crucial role in achieving precise and consistent bends in metal fabrication processes. To ensure the longevity and optimal performance of these molds, it is essential to implement proper maintenance and care. In this article, we will discuss several tips and practices to improve the service life of CNC bending machine molds.

1. Proper Mold Handling

Handle the molds with care to prevent any damage. Avoid dropping or mishandling them, as it can lead to cracks or deformations. When moving or storing the molds, use appropriate lifting equipment and ensure they are properly secured to avoid any accidents or unnecessary stress on the molds.

2. Regular Cleaning and Lubrication

Regularly clean the molds to remove any debris, dust, or metal shavings that can accumulate during the bending process. Use appropriate cleaning solutions and tools to avoid damaging the mold surface. After cleaning, apply a suitable lubricant to reduce friction and wear during operation. Lubrication helps prolong the life of the molds and ensures smoother bending operations.

3. Preventive Maintenance

Implement a regular maintenance schedule for the CNC bending machine molds. Inspect them for any signs of wear, such as cracks, dents, or excessive wear on specific areas. Address any issues promptly to prevent further damage. Regularly check the mold fastening mechanisms, such as screws or clamps, to ensure they are tight and secure.

4. Proper Material Selection

Choose high-quality mold materials that are suitable for the specific bending applications. Different materials have varying hardness and wear resistance properties. Select molds that can withstand the bending forces and stresses involved in your operations. Consult with mold suppliers or manufacturers to determine the most appropriate materials for your specific requirements.

5. Optimal Bending Parameters

Ensure that the bending parameters, such as angle, radius, and material thickness, are set correctly according to the specifications of the molds. Operating the machine within the recommended parameters reduces the risk of overloading the molds and prolongs their service life. Regularly monitor and adjust the bending parameters as needed to maintain optimal performance.

6. Proper Storage

When not in use, store the molds in a clean and dry environment. Protect them from exposure to moisture, corrosive substances, or extreme temperatures. Consider using protective covers or cases to prevent any physical damage. Proper storage helps preserve the integrity and performance of the molds.

7. Operator Training

Train the operators on proper mold handling and maintenance procedures. Educate them about the importance of careful handling, regular cleaning, and adherence to bending parameters. Well-trained operators can help prevent accidental damage and ensure the molds are used correctly.

8. Constant and Production Rate

The uniformly distributed machining allowance of the mold ensures a constant and high production rate and a safe bending process. When the angle remains unchanged, the bending speed and feed rate can also be kept at a high level. In this way, the role and workload of the mold on the CNC bending machine are small, so the heat and fatigue generated are also small, thereby improving the service life of the CNC bending machine mold.

9. keep continuous cutting for as long as possible

In order to obtain a longer service life, the CNC bending machine mold should keep continuous cutting for as long as possible during the bending process. If the mold enters and exits too frequently, the mold life will be significantly shortened. This will increase the thermal stress and thermal fatigue on the cutting edge. Uniform and high temperature in the cutting area is more beneficial to modern hard alloy CNC bending machine molds than large fluctuations.

10. Uniformly Distributed Machining Allowances

An important goal of the CNC bending machine mold in the bending process is to create uniformly distributed machining allowances for each type of bending in each bending process of the mold. This means that different angle bending molds must be used, and the main CNC bending machine mold should be as close as possible to the final shape of the mold in each process.

By implementing these practices, you can significantly improve the service life of CNC bending machine molds. Regular maintenance, proper handling, and adherence to recommended operating procedures will not only extend the molds’ lifespan but also contribute to efficient and reliable bending operations.
