摘要： PURPOSE:To avoid the formation of burr and set the direction of the burr in the direction of width by forming a un-separated edge part by forming a cut-in part in the direction of plate thickness along the edge part of a metal plate in the first process and applying a shearing deformation in the direction of plate width onto the edge part in the second process. CONSTITUTION:Each of clearance and overlap quantity of the upper and lower round cutting edges of a side trimmer is set to each proper value, and a metal plate 3 having a cut-in part in the direction of the plate thickness which is made in the first process is introduced from an intrusion side, and nipped at the point A where the upper and lower separating round cutters 30 and 31 cross. The round cutters 30 and 31 advance in the direction of a pass plate shown by the arrow and and are lapped by a lap quantity S towards the exit side, and therefore, the edge part 3' of the un-separated metal plate is applied with a shearing deformation in the direction of plate width, and a product 4 and trim scraps 5 are separated. The stable nipping is secured by using a round cutter having a flanges 30' as guide, and burrs are burns are generated in the direction of plate width even in case of a soft metal plate.

摘要： PURPOSE:To prevent a wire from vibrating as well as to secure a highly accurate wafer in supporting the wire against a notch, by setting up paired guide rollers, supporting a wire row, at the opposite side to a cut work member holding the wire row in between at regular intervals. CONSTITUTION:A wire row is supported by paired guide rollers 60 and 61, while there is a space between grooved rollers 40b and 40c, and even if a wire 15 runs at high speed, the wire row is in no case vibrated and an interspace of wires is accurately kept up with each other, thus they are forcibly pressed to the work member W. And, in proportion as the work member W is made to go up, these rollers 60 and 61 are moved in both directions along an outer circumference of the work member W by a drive motor and leaving a slight space intact. That is to say, at the outset of cutting, these rollers 60 and 61 maintains the wire row 45, making the member W go up, and in proportion as cutting advances, roller intervals as 60a, 61a 60b, 61b 61c are widened open but after passing the center of the member W, intervals are reduced, coming to position of 60 and 61. Therefore, wire tension is made relatively into being small so that wire disconnection due to tension is preventable.
摘要翻译：目的：为了防止电线振动以及将高精度的晶片固定在一个槽口上来支撑电线，通过设置成对的导向辊，支撑电线排，在保持电线排的切割工件的相反侧间隔时间间隔。构成：在成对的导辊60和61之间支撑一排导线，而在带槽辊40b和40c之间存在空隙，并且即使电线15高速运行，电线排绝不振动，电线被精确地保持起来，从而将它们强制地按压到工件W.并且，随着工件W上升，这些辊60和61沿着两个方向沿着外周移动工作构件W由驱动电动机保持一定的空间。也就是说，在切割开始时，这些辊60和61保持线排45，使得构件W上升，并且随着切割的进行成比例地，辊间隔为60a，61a，60b，61b 61c变宽，但是在通过构件W的中心之后，间隔减小，到达位置60和61.因此，线张力相对较小，从而可以防止由于张力而导线断开。
