Turn-milling is an advanced cutting method that uses the combined motion of milling cutter rotation and workpiece rotation to achieve cutting processing of workpieces, so that the workpiece can meet the requirements of shape accuracy, position accuracy, and the integrity of the machined surface. Turn-mill composite machining is not a simple combination of turning and milling on one machine tool, but the use of turning and milling composite motion to complete the machining of various surfaces, which is produced under the conditions of the great development of CNC technology today. A new cutting theory and cutting technology.
Compared with the conventional CNC machining process, the outstanding advantages of turning and milling composite machining are mainly reflected in the following aspects:
(1) Shorten the product manufacturing process chain and improve production efficiency. A variety of special tools can be installed, and the new tool arrangement can reduce tool change time and improve processing efficiency. Turning and milling can complete all or most of the processing procedures in one clamping, thereby greatly shortening the product manufacturing process chain. In this way, on the one hand, the production auxiliary time caused by the change of the loading card is reduced, and at the same time, the manufacturing cycle and waiting time of the tooling and fixture are also reduced, which can significantly improve the production efficiency.
(2) Reduce the number of clamping and improve the machining accuracy. The reduction in the number of card loadings avoids the accumulation of errors due to positioning fiducial conversions. At the same time, most of the current turn-milling composite processing equipment has the function of online detection, which can realize the in-situ detection and precision control of key data in the manufacturing process, thereby improving the processing accuracy of the product; the high-strength integrated bed design improves the difficulty of Gravity processing capability of cutting materials; the machine tool is equipped with an automatic feeding device, which can realize automatic feeding and continuous operation, and basically realize the assembly line operation of a single machine tool.
(3) Reduce the floor space and reduce the production cost. The compact and beautiful shape design improves the space utilization and makes maintenance and repairs more convenient to maximize customer satisfaction; although the price of a single turn-milling compound processing equipment is relatively high, due to the shortening of the manufacturing process chain and the reduction of equipment required for the product , as well as the reduction of the number of fixtures, workshop floor space and equipment maintenance costs, which can effectively reduce the overall fixed asset investment, production operation and management costs.
