正弦钳是用来加工锥度或斜度工件的卡具,我们使用它加工全复式电枢片落料模槽口及其它工件。过去工件粗刨后,再按划线加工,但双面磨量较大。用正弦钳精制加工后,双面磨量可保持在0.3～0.5毫米之间,提高工效2～3倍。减轻劳动强度,提高了质量。正弦钳是用三角法加工工件的卡具,工件角度按三角形的正弦关系计算, Sinus clamp is used to process taper or slope of the workpiece fixture, we use it to process full duplex armature blanking die notch and other parts. In the past, after the roughing of the workpiece, then according to the crossed processing, but double-sided grinding larger. With sinusoidal forceps processing, double-sided grinding can be maintained between 0.3 to 0.5 mm, improve work efficiency 2 to 3 times. Reduce labor intensity, improve the quality. Sinus forceps is the fixture of the workpiece by trigonometry, the angle of the workpiece is calculated by the sine of the triangle,
