JB/T3663.2—1998
This standard is a revision of JB177176 "Parameters of Heavy General Lathe". When revising, refer to relevant foreign standards and company product samples, combined with domestic conditions. The main changes in technical content compared with the original standard are: the maximum workpiece weight of the specification with a maximum rotary diameter of more than 2000mm on the bed is increased by 1.25 common ratio. From the date of implementation, this standard will replace JB1771-76 at the same time. This standard is proposed by the National Technical Committee for Standardization of Metal Cutting Machine Tools. This standard is under the jurisdiction of Wuhan Heavy Machine Tool Research Institute. This standard was drafted by: Qiqihar No. 1 Machine Tool Factory, Wuhan Heavy Machine Tool Factory, Shanghai Heavy Machine Tool Factory, Qinghai Heavy Machine Tool Factory. 1 Scope
