The processing height capacity range of the DVT500 vertical lathe is ≤ 2950 mm, and the height of general centrifugal cold molds is 2500 - 3000 mm, which is a variable-diameter cylindrical structure. The existing chuck jaw clamping height is below 200 mm, there are relatively large potential safety hazards of insecure clamping, and there is a risk of tipping during the processing of the centrifugal cold mold.
