奇数槽螺纹丝锥的测量、过去我们都是在万能工具显微镜上进行的。牙形半角、螺距由于机床本身精度较高,只做首件测量,唯中径必须逐个测量。在显微镜上测量中径、效率太低而且误差较大。特别是在磨削过程中的工序间测量是很成问题的。由于每个丝锥的中径都要测量,操作者每个班次要跑很多次计量室, Odd-groove thread taps were measured on a universal tool microscope in the past. Tooth half-angle, pitch Since the machine itself is higher accuracy, only the first measurement, only the diameter must be measured one by one. Measuring the diameter on the microscope is inefficient and has a large error. Especially during the grinding process of measurement is very problematic. As each tap’s diameter to be measured, the operator to run many times each shift metering chamber,
