Technical Field

[0001] This utility model relates to the field of automated processing technology. Background Technology

[0002] For rod-shaped workpieces that require machining at both ends Figure 1 The diagram shows the first step in a traditional machining process, which involves clamping one end of the workpiece 30 onto the machine tool's chuck 31 and machining that end. Figure 2 This is a structural diagram of the workpiece before the first processing step in the traditional machining process. Figure 3 This is a structural diagram of the workpiece after the first step of the traditional machining process. One end of the workpiece has been machined.
