江苏50型拖拉机离合器压盘上有六个带圆柱的平面台肩,其外圆φ13和凸肩φ38处平面均有加工要求(如图1所示),过去采用焊有二个合金刀片的平底锶钻进行加工.由于刀片磨损后刀体也随之不能使用,刃磨也较困难。现在采用了机夹体外刃磨式硬质合金端铣刀(如图2所示),解决了生产上长期存在的这个问题。 Jiangsu 50 tractor clutch pressure plate has six cylindrical with a flat shoulder, the outer φ13 and shoulder φ38 at the plane are processing requirements (as shown in Figure 1), the past with two alloy blades welded flat Strontium drilling for processing.With blade body can not be used after wear, grinding is also more difficult. Now using the body outside the sharpening carbide end mill (Figure 2), to solve the long-standing production of this problem.
