The Difference between Fine Blanking and Conventional Blanking
There a number of different engineering firms that all focus on the manufacturing industries to offer their highly qualified skills. Being able to manufacture large quantities of components and parts that need to be used in other production lines is never an easy thing, especially when you have to ensure the precision of each and every item that is produced.
Blanking basically forms a part of this whole process and without it a lot of production lines would have to waste excessive amounts of time focussing on the precision and accuracy of their production when they should be focussing on pushing out the required numbers. If you have machines that are carefully configured to handle mass production like that, then at least you have won half the battle.
Understanding the Process of Blanking and the Difference between Them
Fine Blanking and conventional blanking are essentially the same thing; however they do have one or two minor differences that set them apart from one another. Conventional blanking is basically a type of press where you can feed metal sheeting into it on the one side, and then whenever the press comes down, it cuts out a direct template into the metal and fresh cut component falls out on the other side.
Fine Blanking on the other hand, has an additional support structure that forces the metal sheet to stay completely flat while the template is being cut. The additional support allows the metal sheet to be completely still and totally flat when the press comes down. The end result is that you get a much cleaner cut from the fine blanking than regular conventional blanking.
The need arose when precision parts needed to be produced with100% straight cut edges over the normal 30-40% cut that you get from the conventional method. The press basically has a punch that comes down through the metal and if the metal moves or bends in any way, it will result in a poorly cut edge, that often requires additional finishing making it ready for the rest of the manufacturing process.
Conventional Blank is quicker and more Cost effective
Conventional blanking is a fast and effective way to produce large quantities of components in no time; however it still requires an extra step to make the components ready for use. Essentially, all you need to do is calculate the trade off between the extra step and using Fine Blanking in order to determine which process is going to be better for you in the long run.
