[0002] Machine tools refer to machines for manufacturing machines and machinery. Machine tools play a major role in the modernization of the national economy. Lathes are mainly used to turn rotating workpieces with turning tools. Drills, reamer, reamer, tap, die and knurling tools can also be used on lathes for corresponding processing. Lathes are mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces. They are the most widely used type of machine tools in machinery manufacturing and repair factories. In the process of workpiece processing, auxiliary time such as workpiece loading and unloading and tool adjustment accounts for a considerable proportion of the processing cycle. Among them, tool adjustment is time-consuming and labor-intensive, and it is not easy to be accurate. Finally, trial cutting is required. Statistics show that the pure maneuvering time for processing a workpiece accounts for only about 55% of the total time, and auxiliary time such as clamping and tool setting accounts for 45%. Therefore, tool setting instruments show great superiority.
