When purchasing a precision punching machine, you should consider the appropriate tonnage of the punching machine

The tonnage of the punching machine is one of the important reasons to consider when purchasing a precision high speed punching machine. The main factors affecting the tonnage of precision punching machines include the length of the perimeter of the part, the thickness of the material, and the strength of the material.
     The area of the plate and the length of the stroke are determined by the size and depth of the part. As for the daily production capacity, it is mainly used to calculate the strokes per minute of the precision punching machine and the number of punching machines required to meet the overall production demand. Based on this, the various characteristics are considered together, including parts processing characteristics, material characteristics, tool characteristics, etc. For blanking, piercing and other processes, short-stroke high-speed punches are required; A punch with a long stroke and a relatively slow speed is used. When it is used for stamping, embossing, etc., a short-stroke punch with high energy at the bottom dead center must be used.
     It can be seen that the larger the tonnage of the punching machine, the higher the price of the punching machine. Here we remind new and old customers not to care about the price of the punching machine blindly when purchasing a punching machine.

     Bending and forming of precision punching machines generally use A2-level punching machines. For example, when the precision of the parts, especially the springback, is very strict, the bending of phosphor bronze and other thin plate parts with a small allowable error in plate thickness can only be achieved by using A1-level punching machines. required precision. Therefore, the difference in the thickness of the workpiece material is more important than the punch specification. If there is no problem in the accuracy of the 2-level precision material when it is bent and formed, better results can also be obtained by using a B2-level punch. However, such sheets are sometimes mixed with thick and hard materials, causing the mold to be overloaded. For example, the precision punching machine has good rigidity and may not deform, but it will cause damage or deformation of the mold.
