Mechanical Industry Standard of the People's Republic of China JB/T3663.2-1998 Heavy Horizontal Lathe Published on July 17, 1998bzxz.net National Bureau of Machinery Industry Implemented on December 1, 1998 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 Machinery Industry Standard of the People's Republic of China Heavy Horizontal Lathe This standard specifies the parameters of heavy horizontal lathes. JB/T3663.2—1998 Replaces JB1771—76 This standard applies to general-purpose heavy horizontal lathes with a maximum rotary diameter of 1000~5000mm on the newly designed bed and a maximum workpiece weight between the centers equal to or greater than 10t. 2 Parameters The type of heavy horizontal lathe is shown in Figure 1. The parameters of the machine tool should comply with the provisions in Table 1 Figure 1 Maximum rotary diameter D on the bed Maximum workpiece length L Maximum workpiece weight between centers Types of heavy-duty horizontal lathes Parameter table of heavy-duty horizontal lathes Note: The parameters in the table are the basic series values. If the user has special requirements, they can be negotiated with the manufacturer.
