Spherical diameter of Sφ2310 ~ Sφ1070mm, more production specifications. With the tolerance of H9 / f9, finish requirements R_α3.2. Since 1980, our factory has designed a series of spherical surface-type turning devices for C5225, C5235 and C5250 vertical lathes, which have successfully solved the turning of the large inner and outer spherical surfaces of this product. Years of production practice shows that the device is easy to manufacture, simple and easy to use, versatility and so on. First, the device structure and features The device consists of two parts of the arbor and the model by the sample (see Figure 3, Figure 4), the first piece of the connecting rod taper shank and vertical turret Taper match, the pieces of 3 Arbor through Slide the guide key 6 in the 2-piece seat.
