The application of combined cutting tools in the combination of multiple processes

only by combining multiple processes in one process and minimizing the auxiliary time, it is possible to produce workpieces in batches economically. This can be achieved with combined tools. The combined cutter can drill holes with different diameters, and can mill the end face, countersink, chamfer, ream or turn threads during rotation. Combined cutters are especially suitable for complex workpieces that need to be processed with multiple cutter series. It used to be that the tool should be changed after drilling, chamfering or turning thread every time, but now it can be completed in one clamping. This significantly reduces the number of tools needed to process the workpiece and the space occupied by the corresponding tool magazine. One combined tool can replace 5 ~ 10 conventional tools. In the case of processing complex workpieces, because the beat time is shortened, the processing time can be reduced by about 70%, thereby saving the purchase cost of cutting tools. However, the advantages of this multifunctional tool are far from limited to simplifying tool management and reducing the cost of purchasing tools and inventory. Because all cutting is arranged on the tools closely arranged with each other, the position between the blades is accurately determined, resulting in high precision, which reduces the inspection cost and simplifies the quality assurance work

the machining accuracy of combined tools depends on the tool itself. This is better than relying solely on machine tools to obtain accuracy. Therefore, this kind of tool is more suitable for processing particularly precise workpieces. Although it was originally designed for large and medium batch processing, it also shows its advantages in the case of repeated small batch processing

the variety range of combined tools has been extended from simple graded drilling to highly complex tools with various cutting materials, which are applied to different production tasks and are composed of multiple parts. The so-called multi technology tools can drill holes, chamfer, mill countersinks and mill threads in one process, or can carry out hard cutting and soft cutting, as well as rough machining and finishing machining. Due to the high accuracy of the cutter, the machining allowance for finished product processing is significantly smaller than that left by using two kinds of cutters. The result is that the surface quality and durability of the workpiece are improved

modules with ultra-fine structure (HFS) can be assembled according to the quality of the tension machine according to the needs of production. 3. The gas medium used in this system must be kept clean, which can be roughly distinguished from the tension range and measurement accuracy. Through the HFS interface with 3mm accuracy, the tool made of multi segment module can be combined. The machining allowance for finishing is only a few percent of mm in total. Modular structure simplifies tool regrinding. The advantage of the tool replacement module is that it can replace a module simply, quickly and with high precision in the case of changing the workpiece. When necessary, the replacement can be completed even within the working hours of the machine tool

nowadays, the combination of general machining centers and combined tools can create the productivity that can only be achieved on special machine tools in previous years. Three kinds of technological innovations have broken through the other constraints of high productivity machine tool processing: the spindle with high stability and extreme radial oscillation; Precision HSK tool holder and tool material and coating device suitable for high-power cutting. In the last decade, the technological progress in this field has been remarkable. The development of technology has effectively improved the durability of cutting tools, and the combination of cutting tools is more practical

in addition, due to the great development potential of cutting materials and coating technology, the application ability of cutting tools will be further improved. Another driving force is dry cutting technology. Although people have studied this technology for a long time, it needs to be further developed to enter practical application. Finally, using cemented carbide tools, PKD tools and CBN tools with improved geometric parameters can realize machining with micron accuracy, which will further expand the application of tools

a further trend is to develop platform oriented tools. For tool production, this means that we should refer to the practice of the automobile manufacturing industry: according to the production 3, choose the correct cleaning method and change the task, carry out a reasonable combination or change the cutting and function modules. Its main advantage is that it can manufacture various special cutting tools quickly and cheaply. Another development trend is to develop cutting tools according to mechanical principles. At present, there have been schemes that can make the tool fine adjustment, rough machining and finishing operations

since it is necessary to tailor the clothes for each work task, the combined cutters are usually specially made. However, their price will not be more expensive than that of general-purpose tools, because only higher productivity is enough to make up for the additional cost of production. Of course, it is worth using combined cutters when the production batch size needs to be determined according to the actual situation. Those manufacturers who have this intention not only need to provide cutting tools, but also need to formulate a complete production process plan based on user data
