宇顺力三刀式采用独特的切割方法，电路板du切割由六zhi片刀片完成，上下两片为一dao组，构成一个切割单元。分别是 A、B、C、三组。整个切割过程分为三个阶段，A 组刀片先切割电路板 40%，接着 B 组刀片再次从 A 刀片切过的槽中碾过，再次完成 40% 的切割量，最后由 C 组刀片切割最后的 20% 并修光，由于每次的切割量很小，因此切割过程中产生的应力较传统的一次切断方式减少了 80% 以上。分割好的电路板边缘平整光滑、板面非常平整、不扭不翘。是目前市面上唯一的能保证切割后铝基板不变形的机器。
The unique cutting method is adopted in yushunli three knife type board dividing machine. The Du cutting of circuit board is completed by six pieces of blades, and the upper and lower pieces form a Dao group, forming a cutting unit. They were group A, group B, group C and group C. The whole cutting process is divided into three stages. Group a blades first cut 40% of the circuit board, then group B blades again roll through the slots cut by blade a, finish 40% of the cutting volume again, and finally cut the last 20% and polish by group C blades. Because the cutting amount is very small each time, the stress generated in the cutting process is reduced by more than 80% compared with the traditional one-time cutting method. The edge of the divided circuit board is flat and smooth, and the board surface is very flat without twisting and warping. It is the only machine on the market to ensure that the aluminum substrate is not deformed after cutting.
