Turning-based compound machining machine
This type of machine tool integrates milling, drilling and tapping, boring, grinding, and gear hobbing and gear shaping on the basis of horizontal turning centers and vertical turning centers. machining machine. Representative M65 and M60-G from Austrian WFLMillTunTechnologies; 100Ⅲ, 200Ⅲ, 300Ⅲ series, QTN100MS, 250MSY, 350M series from Japan MAZAK Company; TRAUBTNX65 from German INDEX Company; TWIN65 from DMG Company, etc. Compound machining machine.
The M65 horizontal turning-milling compound machining machine exhibited by Austrian WFLMillTunTechnologies at the exhibition is representative. The machine tool adopts the traditional horizontal lathe layout in general, the bed adopts a highly rigid 60° inclined bed structure, and the guide rail is a specially designed large-size linear guide with high rigidity and excellent vibration resistance. The left end of the bed is the turning headstock with C-axis function. The right end is the tailstock device. The upper part of the inclined bed is a turning, milling, and boring spindle device, which can perform linear motion along the longitudinal (Z-axis), transverse (X-axis), and radial (Y-axis) and swing and rotary motion of the B-axis. In addition, the B-axis can be indexed in 2.5° units with the ability to perform whirling milling and roughing. The lower part of the inclined machine bed is a center support that can be maneuvered in both longitudinal and transverse directions, which is used to support the workpiece when the tailstock device cannot be used for end face and boring inner hole processing. In this position, the M60-G is a double-cutter type turning rotary tool holder, which can participate in simultaneous machining in both longitudinal (Z1 axis) and lateral (X1 axis). Therefore, the machine tool has the function of X, Y, Z, B and C multi-axis interpolation and linkage, and can perform turning, drilling, milling, grinding, gun drilling, internal and external gear machining, turning and milling, circular machining without human intervention. Machining tasks such as arc milling. The machine is equipped with a wear-free, maintenance-free disc magazine with up to 120 tool positions behind the headstock to replace the traditional chain magazine, which can store tools up to 900mm long and weighing up to 20kg. The tool change position is located above the spindle of the headstock at the left end of the machine tool. In order to reduce the non-productive time waste caused by the reciprocating movement of the turning and milling spindle during tool change, the tool change position is programmed in the program library within the full longitudinal stroke. The second tool support attachment located below the machine tool's turning and milling spindle adopts a unique and strong dovetail structure, which can be installed with deep hole drilling shanks, WFL series boring bars, integral drills, internal cavity machining live tools and special profile boring. Large knives, such as knives, that are much larger than standard knife sizes. There is a tool changer table above the spindle at the right end of the machine tool, which can automatically store up to two large tools with a length of 1550mm and a weight of 150kg. Deep hole boring bars and internal cavity machining live tools can be loaded with a variety of machining tools, can be taken directly from the left-hand tool magazine, and can be operated by a separate machine sliding door without interrupting machining. When processing the inner and outer circles of the workpiece at the same time, it can achieve extremely high coaxiality, and at the same time ensure the positional accuracy of boring and milling surfaces.
Milling-based compound machining machine
This type of machine tool integrates turning, drilling and tapping, boring, grinding, and gear hobbing and gear shaping on the basis of horizontal machining centers and vertical machining centers. machine tool. For example, the INTEGREXe-800V/5 and e-1550V10 horizontal milling-turning compound machining machine tools of Japan MAZAK company add the rotary turning function to the worktable of the five-axis horizontal machining center, which can realize the realization of circular disc parts in one loading and clamping. Complete machining of turning, milling and other processes. The INTEGREXe-500HS vertical milling-turning compound machining machine is equipped with a rotary spindle with a chuck at the left and right ends of the machine tool. At both ends, the machining work of turning and milling of two short shaft parts is carried out at the same time.
Other compound processing machine tools
In addition to the above two types of more popular compound machining machine tools, there are many other types of compound machining machine tools in this exhibition, such as DMG company's DMC60S for bar machining, Switzerland WILLEMIN company's W-518MT and so on. Grinding-based and grinding head rotary (or exchangeable) compound machining machine tools, and other compound machining machine tools that combine various processes such as laser processing, stamping, and heat treatment. In a word, the composite processing machine tools in this exhibition are large in scale, many varieties and high level, it can be seen that the development of composite processing machine tools is in the ascendant. Combining the development of numerical control technology, software technology, information technology and reliability technology, the future composite machining machine tool will develop towards the direction of simplified components, compact structure, modular configuration and commercialization of components. The performance of compound machining machine tools will also be diversified according to the processing requirements of users. A compound machining machine with suitable functions for exclusive use of production conditions. At the same time, compound machining technology also has broad development prospects on heavy and large machine tools. Compound machining is an important direction for the development of machine tools in the future.
