Turn-Milling Compound Machining Center refers to the place where lathe and milling machine are processed together. It is an advanced cutting processing method that uses the combined motion of milling cutter rotation and workpiece rotation to realize the cutting processing of the workpiece, so that the workpiece can meet the requirements in terms of shape accuracy, position accuracy, and processed surface integrity. Compared with conventional CNC machining technology, the outstanding advantages of Turning-Milling-Compound-Machining-Center are mainly reflected in the following aspects: (1) Shorten the product manufacturing process chain and improve production efficiency. A variety of special tools and new tool arrangements can be installed to reduce tool change time and improve processing efficiency. Turning and milling composite processing can complete all or most of the processing operations in one clamping, thereby greatly shortening the product manufacturing proc...
