In the epoch of smart manufacturing, order requests are often with lower quantity but great diversity, so the machining centers are one of the most efficient processing ways of metalworking solutions in the industry today due to its higher machining capability and advanced durability through all the cutting duties. The idea of the machining center and 5 axis machining centers is derived from the milling machines, or, specifically programmed CNC milling machine. That is, there is a vague distinctive area in between whether milling-based machinery is a machining center or simply a milling machine.
To explain more about this in a simple way is that, there is a wide spectrum of milling-based machine tool inventory. While conventional manual milling machines stand at the one end, and multiple axis CNC machining centers with automation system equipment stand at the other end. Conventional machining centers are designed at least with three axes, namely, x, y, and z, and for both vertical and horizontal models, either one could be equipped with other axes to build 5 axis machining centers.
In the design of 5 axis CNC machining centers, the rotary table plays an important variable with the other additional two axes designed on the base, which are the x, y, and z-axis which can move onto two new working dimensions that permit multiple angles of possible cutting processes, granting the versatile and complex profile cutting route.
The utilization of 5 axis CNC machining centers for complicated processing on hardened workpiece materials has long been concerned as high-end advanced multi-axis CNC machines for industrial insiders. It is well known that ever since the functionalities of milling center is improved to a certain level that normal milling center can no longer keep up with, calling it a milling center or CNC milling machine is not appropriate anymore. Therefore, the term multi-axis CNC machining center is made.
In the metalworking industry, the machining center is one of the most efficient machinery of metalworking solution in the modern industry currently. Among all the classifications, there are mainly three types of compositions that constitute a 5 axis CNC machine. Here we introduce them in the following text. For the first one, swing head alone is a type of multi-axis CNC machines that is able to achieve most processing angles, and this kind of CNC machine is considered convenient as well as other 5 axis CNC machines, such as four plus one, and 3+2 axis CNC machine, while the latter are with more practical advantages due to the existing three-axis compositions.
Traditionally, the machining center is designed at least with three axes, namely, x, y, and z, and for both vertical and horizontal models, either one could be equipped with other axes in order to make the machine 5 axes capacity. And which is called 5 axis CNC machining centers. With the other additional two axes designed on the rotary table, the x, y, and z-axis can move onto two new working dimensions that permit multiple angles of possible cutting processes. The same with the 4+1 structure and all these mechanisms are under the control of a computer numerical control unit that makes synchronized actions perfectly matched with the intended accuracy and performance.
If the size of a workpiece is too big and wider than the size allowed, the machining would cause too much vibration to the machine body and thus deteriorate the precision frame of the machining center. That is not an acceptable situation to both manufacturers and the following supply chains. Hence, manufacturers might add some other structural designs onto the body in search of making it with better rigidity during the milling process. Regarding its milling capacity, as its name tells, is the process of machining that utilizes spinning tools to remove workpiece materials by advancing a tool into one or several workpieces. The process of 5 axis CNC machining centers could be achieved on different angles due to the additional phases. In the metalworking sector, the milling process of the machining center covers a wide variety of various operations and ranges a wide scale from single tiny parts to heavy and large milling operation tasks.
Regarding the second kind of 5 axis arrangement, it is the 4+1 structure. It is under the construction of a 4+1 axis machine with one more additional axis as the base part, offering one more additional axis to the existing four axes for the operators. And the third kind is 3+2 axis structures, which is a three-axis machine added with a two-axis swing bed, offering additional moving capacity. Some manufacturers may add columns to the machining center, granting not only one more axis mobility but also better vibration resistance. Double column plus 5 axis functionality is one of the very practical solutions to solve the machining vibration issues while improving the accuracy at the same time. CNC Double column machining centers are a sophisticated metalworking machine tool that can deal with many kinds of machining tasks all at once.
Regarding the milling process of the double column machining center, it is the process of machining that utilizes spinning tools to remove workpiece materials by advancing a tool into one or several workpieces. This cutting procedure could be done in different directions which are based on the box in box ways just like turning machines. In addition to turning, milling covers a wide variety of various operations and ranges a wide scale from single tiny parts to heavy and large milling operation tasks. Therefore, the study and development of the milling method are highly popular in the industrial world due to its productive and effective nature for rendering workpieces with complex profiles which are comparatively hard to achieve by conventional turning lathes. With this expectation, the following development and the idea of machine center are thus gradually formed. The phrase “machining center” can be used to describe a wide variety of CNC (Computer Numerical Control) drilling and milling machines that are accommodated with several critical but sometimes optional accessories equipped together with the machine body itself, such as tool magazine, ATC (automatic tool changer), power tool turret, CMM (Coordinate Measuring Machine), multi-axis working tables.
The double column machining center is generally classified into two types: either fixed column or moving column. The former is the design that both columns stay where they are without the possibility of moving, and the latter allows for another axis to be born, thus greatly improves the convenience of machining. CNC 5 axis Double column machining center is a highly developed machine tool that can deal with many kinds of machining tasks, after the development of the 5 axes, the development of this specific type of machine tools goes well in the industry, and after that, machine center is profoundly applied in all kinds of industries, contributing a wide range of industrial usages.
