The Turn-mill Combination machine tool of turning and milling is the most widely used numerical control equipment in the compound machine tool.It’s is one of the important directions of machine tool development.The turn-mill Combination also includes turning and milling compound, turning and milling compound, milling and grinding compound and other various forms, the purpose of compound is to let a machine tool with versatility. It’s can be a clamping to complete multiple tasks, and improve processing efficiency and accuracy.
Compared with the conventional CNC machining technology, the Turn-mill Combination machining has outstanding advantages mainly in the following aspects.
(1) Shorten product manufacturing process chain and improve production efficiency.The Turn-mill Combination machining can be complete all or most of the machining processes at one time, thus greatly shortening the manufacturing process chain of products.In this way, the production auxiliary time caused by the change of tooling and fixture is reduced, and the manufacturing cycle and waiting time of tooling are also reduced, which can significantly improve the production efficiency.
（2）Reduce the number of clamping, improve machining accuracy.The reduction of clamping times avoids the error accumulation caused by the conversion of positioning datum.At the same time, most of the Turn-mill Combination machining equipment has the function of online detection, which can realize the in-situ detection and precision control of the key data in the manufacturing process then improve the machining accuracy of products.
