What does it mean to have a rough die
The tool is used to process the rough shape of the mould. And the machine tool and cutter that open coarse use is less accurate, such processing speed is relatively quick. It needs to be left with a residual amount, and then replaced with a processed machine tool and tool. Die strategy: Follow the perimeter: less knife, more clean blade, more empty blade, suitable for electrode processing, avoiding the phenomenon of the cutting of the knife in electrode processing. Follow the workpiece: it is not easy to cut, the way is safe, it is suitable for steel material processing, lifting the knife.
After the steel purchase comes, the first is to open the thick The so-called roughing is to process the rough shape of the molds with the machine tool. And the machine tool and cutter that open coarse use is less accurate, such processing speed is relatively quick. You need to leave a residual amount for the opening Then the processed machine tool and cutter continue to be processed
The rougher is to cut off the material first. Some of the large excess is removed.
The simple thing is that it is a crude process, and it will be a quick removal of a large amount of excess material, but it is not the same
