How to evaluate the punching accuracy of Manhart (Guangdong) CNC Machine Tool Co., Ltd.’s CNC punching machine?

The punching accuracy of CNC punching machines can be evaluated through the following aspects:
1. Aperture accuracy: Evaluate the difference between the diameter of the hole punched by the punching machine and the theoretical value, which mainly involves the processing ability of the equipment and the accuracy of the control system.
2. Hole position accuracy: Evaluate the difference between the position of the hole punched by the punching machine and the theoretical position, which mainly involves the positioning accuracy and repeated positioning accuracy of the equipment.
3. Hole shape accuracy: Evaluate whether the shape of the hole punched by the punching machine is regular, and whether there are defects such as deformation and burrs. This mainly involves factors such as cutting force of the equipment, tool quality, and cutting parameters.
In order to obtain accurate evaluation results, professional measuring tools such as vernier calipers, microscopes, etc. can be used to measure the holes punched by the punch hole machine. At the same time, statistical methods can also be used to measure multiple holes punched by the punching machine, analyze the error distribution in terms of aperture, hole position, hole shape, etc., and comprehensively evaluate the punching accuracy of the punching machine.
It should be noted that punching accuracy is influenced by various factors, such as the design of the equipment itself, manufacturing process, and usage environment. Therefore, in practical use, it is necessary to comprehensively consider the specific situation and take corresponding measures to improve punching accuracy.
