In the era of intelligent manufacturing, machine tools with intelligent functions are popular. Five axis cutting is one of the highly researched and developed machine tool models. Due to its multi-task processing and convenient machine tool design, it can process multiple types of machining tasks in one stop.
In fact, at the beginning, the machine center evolved from the design of the vertical milling machine in the mid-20th century. The research and development of this specific type of machine tool have experienced continuous progress in the laboratory and industry. Since then, diverse machining centers have been widely used in all kinds of industries for professional and precision usages, contributing a broad range of industrial achievements and rendering a very wide range of practical usages.

In fact, the term "5-axis" can be used to describe a variety of CNC (computer numerical control) milling and drilling machinery that include several critical accessories designed and assembled together with the machine frame. For example, tool magazines (there are different types of magazine design), ATC (automatic tool changer), power tool turret (hydraulic, powered), CMM (coordinate measuring machine), and multi-axis table (with different rail motion design). Speaking of 5-axis, in the machine tool inventory, besides vertical and horizontal models, there are other categories in the machining center inventory. This is a way of classification.

In addition, the vertical machining center is a vertical arrangement of its structure, so the workpiece is processed by cutting tools that move up and down. At the same time, as opposed to vertical machining centers, horizontal machining centers have spindles arranged horizontally, and the machining process is not processed vertically. For vertical and horizontal models, both can be equipped with 5 axes. Regarding the 5 axis machining center, there are three main methods of constructing five-axis motion. All the machining angles can be realized by the swing head. The machine's swing head model and other 4 + 1 and 3 + 2 machining centers are considered convenient, and the latter two are with more practical advantages such as great flexibility and practical prices.
There are many ways to go to Rome. Normally the 3 + 2 model is a conventional three axis CNC machining center, which will be installed together with another table whose mechanism contains two other axes. This is the case for axes combinations. Therefore, with the two axes designed on the rotary table (ie, working table), the x, y, and z axes can be moved to two new working dimensions, so that multiple angles of possible cutting processes can be performed. The same structure as 4+1, all these mechanisms are processed under the control of the computer numerical control unit, so that the synchronized action perfectly matches the target accuracy. In the field situation, if the size of the workpiece is too large, the processing will cause too much vibration to the machine body, and reduce the accuracy of the machining center. Therefore, the manufacturer may add some other structural designs on the body to perform in order to give it advanced performance and bring real productivity.

As a result, in many designs on the market, the double column is one of the very practical solutions to solve the vibration problem of machining while improving accuracy. Double column machining centers are usually divided into two types: fixed columns or moving columns. The design of the former is that neither of the two columns can be moved, while the latter allows the birth of the other axis, thereby greatly improving the convenience of machining and machining procedures.
In addition, the gantry type machining center is a highly developed machine tool that can handle many heavy precision machining tasks at once. At the beginning, the gantry type machining center was developed from a milling machine in the middle of the last century. The development of this specific type of machine tool has been going smoothly in the industry. Since then, the machine center has been widely used in all fields and has made great contributions to the development and evolution of world industry. Although the two are very similar in many aspects in common, the milling process is a machining process that uses a spinning tool to remove workpiece material by advancing the tool into one or more workpieces. This processing method can be done in different directions. In addition to turning, milling also involves a variety of operations, ranging from a single tiny part to heavy and large milling tasks. Similar to turning, milling is one of the most commonly used machining methods, which can achieve precise tolerances within accurate standards.
