Pressure, and thereby chapped.

The existing splitting machines are often used in quite sophisticated items, such as wafers, so the motion requirements are quite accurate, even the upper and lower feed distances of the splitting knife are the same; however, under high precision inspection The thickness of each target is not necessarily the same, or even the same target is uneven due to its uneven surface, so the thickness of the different parts will be slightly different, and these factors will affect the infeed stroke of the splitting knife. If the splitting knife is too deep, it may split to other places where it should not be split, or if the cutting is too shallow, it will not completely break the target.

Therefore, in order to solve the problem of the splitting knife, some people will manually measure the thickness of the target before each feeding. However, the error of the cutting edge of the splitting knife may be difficult to judge with the naked eye. Otherwise, it must be Complex measuring instruments can be viewed, and in either case, it can cause operator troubles and greatly affect work efficiency; especially when used on wafers, it may need to be cracked dozens or even dozens of times, and each Before the splitting, it is necessary to measure the thickness of the place again, and it will greatly lengthen the working time.
