Adjustable Stroke Power Press Punching Machines

We are a professional Adjustable Stroke Power Press Punching Machines manufacturer with over 10 years of industry experience. Today, we would like to introduce to you:

The national standard for precision testing of Adjustable Stroke Power Press Punching Machines is to ensure the accuracy requirements of punch presses during operation, thereby ensuring product quality and improving production efficiency. 

This product precision standard refers to the accuracy requirements that can be achieved during operation, mainly including its position accuracy, dimensional accuracy, repeatability, parallelism, perpendicularity, and surface roughness. For example, the positional accuracy of the punch press is required to be within 0.01mm, the dimensional accuracy and repeatability accuracy are required to be within 0.02mm, the parallelism and perpendicularity are also required to be within 0.02mm, and the surface roughness is required to be within 0.8.

In addition, the precision testing standards for punching machines also include precision checks for mechanical presses weighing up to 250 tons. The precision levels of punching machines are divided into Level 1 and Level 2, with precision suitable for high-precision processing applications such as thin plate precision punching and high-speed precision punching. Level 1 precision is suitable for thin plate stamping, high-speed stamping, stretching, and other applications, while Level 2 precision is suitable for general stamping, stretching, forming, and other applications.

The detection methods include geometric accuracy detection, motion accuracy detection, dynamic accuracy detection, and functional accuracy detection. Geometric accuracy detection is achieved through measuring instruments such as coordinate measuring machines, laser interferometers, etc., to detect the relative positions and dimensions between the various components of the punch press. Motion accuracy detection detects the accuracy of the moving parts of the product during the motion process, such as straightness and roundness; Dynamic accuracy detection checks the accuracy stability of punch presses during actual processing, including the influence of factors such as vibration and thermal deformation; Functional accuracy testing ensures that its various functional components can accurately perform their functions.

In short, the national standard for precision testing of Adjustable Stroke Power Press Punching Machines is a comprehensive system that covers multiple aspects of precision requirements. Therefore, in practical operation, it is necessary to select the corresponding standards and precision levels according to the specific situation, and carry out corresponding control and testing.
