How to ensure the machining accuracy of high-precision oil electric servo CNC bending machines?

Ensuring the machining accuracy of high-precision oil electric servo CNC bending machines is a comprehensive task that involves multiple factors and operations. Here are some key steps and precautions:
1. * * Material selection and preparation * *:
-Choose materials with good quality and uniformity, and avoid using low-quality or defective materials.
-According to the processing requirements, select the thickness and type of materials reasonably to ensure that the materials are not easily deformed or produce uneven stress distribution during the bending process.
2. * * Process adjustment and optimization * *:
-Adjust process parameters such as bending angle, bending speed, and bending force based on material properties and bending requirements to ensure stable and reliable bending process.
-Before processing, conduct a trial fold and adjust the process parameters based on the trial fold results until satisfactory processing accuracy is achieved.
3. * * Machine structure and accuracy maintenance * *:
-Choose a machine tool structure with high precision and stability, such as a high-precision hydraulic machine tool or an electric motor bed, to ensure the rigidity and accuracy of the machine tool.
-Regularly inspect and maintain the mechanical components and transmission system of the CNC bending machine to ensure their accuracy and stability.
4. * * Selection and maintenance of cutting tools and molds * *:
-Choose high-quality and high-precision cutting tools and molds to ensure that they can stably control the bending angle and force during the machining process.
-Regularly inspect and repair cutting tools and molds, replace worn or damaged parts in a timely manner, and avoid affecting machining accuracy.
5. * * Servo system and control strategy * *:
-Utilize high-precision servo motors and control systems to achieve high-precision control of workpieces. By precise servo motor control, the bending angle and position of the workpiece are ensured to be accurate and error free.
-Select appropriate control strategies based on processing requirements, such as position control, speed control, or force control, to achieve high-precision bending of the workpiece.
6. * * Operator Skills and Training * *:
-Operators need to have certain CNC programming and operation skills, be familiar with the usage methods and precautions of CNC bending machines.
-Regularly train and assess operators to improve their skills and operational experience, ensuring that they can accurately control the machining accuracy of CNC bending machines.
7. * * Processing process monitoring and quality inspection * *:
-During the machining process, use appropriate inspection tools and methods to monitor and inspect the dimensions, angles, and surface quality of the workpiece in real-time.
-Conduct quality inspection on the processed workpieces to ensure they meet the machining accuracy requirements. For unqualified workpieces, adjust and handle them in a timely manner.
In summary, ensuring the machining accuracy of high-precision oil electric servo CNC bending machines requires comprehensive consideration and operation from multiple aspects such as material selection, process adjustment, machine maintenance, tool and mold selection, servo system and control strategy, operator skills, and machining process monitoring and quality inspection. By continuously optimizing and improving these factors, the machining accuracy and stability of CNC bending machines can be improved, thereby meeting the needs of high-precision machining.
