宇順力三刀式分板機采用獨特的切割方法，電路板du切割由六zhi片刀片完成，上下兩片為一dao組，構成一個切割單元。分別是 A、B、C、三組。整個切割過程分為三個階段，A 組刀片先切割電路板 40%，接著 B 組刀片再次從 A 刀片切過的槽中碾過，再次完成 40% 的切割量，最后由 C 組刀片切割最后的 20% 并修光，由于每次的切割量很小，因此切割過程中產生的應力較傳統的一次切斷方式減少了 80% 以上。分割好的電路板邊緣平整光滑、板面非常平整、不扭不翹。是目前市面上唯一的能保證切割后鋁基板不變形的機器。

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.
