The determination of the placement position of the CNC machined workpiece on the worktable should take into account the processing of each station, and the influence of the length of the tool and its stiffness on the processing quality should be considered. For single-station and single-sided processing, the workpiece should be placed in the center of the worktable on the side of the worktable. In this way, the extension length of the shank can be reduced and the rigidity of the tool can be improved.

Row jig is a mobile jig used in automatic production line. In addition to completing the positioning and clamping of the workpiece, the accompanying fixture also transports the processed workpiece to the machine tool fixture of each machine tool by the transport mechanism according to the process flow of the automatic production line, and is positioned and clamped by the machine tool fixture. There are many types of commonly used tools in CNC machining centers. According to the use of the tools, complex structural parts such as beams are the main bearing parts of the aircraft.





It directly affects the comprehensive performance and development cycle of the aircraft, and its CNC machining capability is an important indicator to measure the level of a country's aviation manufacturing. Thread machining on CNC lathes occupies an increasingly important position in machining due to the advantages of high machining accuracy, good product uniformity, and wide machining range. Processing of completely different properties can be realized on the compound processing machine.

Composite machining is an important technical development direction of CNC machine tools. The compound function can greatly eliminate the transportation, clamping and waiting time during the processing of the hashing process. In addition to the linear interpolation and circular interpolation functions, the machining center also has various processing canned cycles, automatic tool radius compensation, tool length Automatic compensation, graphic display of processing process, man-machine dialogue, automatic fault diagnosis, offline programming and other functions.

There is no need to make any complicated adjustments to the machine. This saves many special samples and standard samples, and shortens the production preparation cycle. With the rapid development of CNC technology, the popularity of CNC machine tools in the manufacturing industry continues to increase, but not all parts are suitable for processing on CNC machine tools.
