金属切削加工中，常遇到如图1所示大型高精度内球面轴承座的工艺难题。由于轴承座中心高超过600mm，致使在C61125以下普通车床上已无法加工，后来在现有设备3．4m立式车床上，设计、应用了如图2所示的车内、外球面工艺装置，使这一工艺难题得以解决。1．构成如图2所示，在立式 Metal cutting, often encountered as shown in Figure 1 large-scale high-precision spherical bearing process problems. As the bearing center height of more than 600mm, resulting in C61125 the following ordinary lathe can not be processed, and later on the existing equipment 3.4m vertical lathe, the design, application of the car shown in Figure 2, the spherical device, Make this process difficult problem solved. 1. Composition as shown in Figure 2, in the vertical
