Digital rotary tables are rotary tables that are calculated with digital calculations.
The digital rotary tables are in one of the most significant categories regarding the automatic processing in the machine tool industry, since the capabilities they have bring a higher level of the operations. For instance, the tilting capability they offer makes more machining processes available as more machining angles can be achieved.
The rotary table is a necessary component in the automatic operation as well. It can be in conjunction with the spindles, saddles, motors, hydraulic cylinders, chucks, screws, etc., which are the parts that can be often seen on a machining center, for example. Combined with these components, the invention of the rotary tables brings more profits to the machine tool industry in Taiwan.
Digital rotary tables are also applied to grinding processing as well. It offers strength for supporting the workpieces and convenience for the abrasive wheels to grind on the workpieces during the grinding process. When it comes to surface grinding, which is the process before an end product is made, the surfaces of the products that come in flat or other specific shapes are ground without the remaining chops or burrs.
As the need of grinding different surfaces on a product increases, the application of a digital rotary table can help a lot in reaching this achievement. That is, when conducting the grinding process with a digital rotary table, it refines what the milling processes can bring to the products being made.
For digital rotary tables to be used in the machine tool sector, especially in the advanced applications, 5 axis bridge type machining center is a highly developed machine tool that is able to handle various tasks in one operation, which eliminates the need of transferring one workpiece to several working sites.
The development of digital rotary tables can be derived from the mid-20th century, which began from the conventional milling machines and transformed into the machining center that is in charge of automatic operation nowadays. This makes the adoption of machining centers covers a wide range of industries, contributing a wide range of industrial demands.
Milling is the process of machining that utilizes spinning tools to remove workpiece materials by advancing a tool into one or several work pieces with better cutting capacity and performance. As a result, this machining method could be done in different directions. It is another level of machining techniques that can deal with the machining of either tiny parts in mechanisms or heavy-duty operations. Milling is as common as turning and both are dedicated to changing the original shapes, forms, or properties of the workpieces with intricate profiles, in order to meet the requirements of the products that the customers long for.
Furthermore, as one of the classic but always useful types in the machining center family, bridge type machining center is a highly developed machine tool that can especially deal with heavy-duty operations. With a bridge-like frame that contains automatic tool change and transfer functions, the workpieces can be secured in the center worktable under the bridge, and receive the various machining processes without the limitation of space and product intricacy as in the conventional form of milling machines. From the mid ages of the last century until now, the development of this type of machine tools has made a difference and opened a new chapter in the prosperous future of the machine tool industry.
So, machining centers are derived from the milling machines, the milling process of the bridge type machining center is the process of machining that uses spinning tools to remove workpiece materials by advancing a tool into one or several work pieces, just like ordinary milling machineries.
By adopting the digital rotary table, the available machining orientations can be achieved with at least three axes as in the general construction of machining centers.
As the above introduction has mentioned, milling is another level of machining techniques that can deal with the machining of either tiny parts in mechanisms or heavy-duty operations. Milling is as common as turning and both are dedicated to changing the original shapes, forms, or properties of the workpieces with intricate profiles, in order to meet the requirements of the products that the customers long for.
That is to say, the application and practical natures of machine centers stimulate the development of milling methods, which is later highly popular in the industrial world that demands for even strict machining accuracy. The effectiveness and productivity that this kind of machining center can provide surpass the functionality of the conventional turning lathes with a significant degree. Based on this expectation, the following development and the idea of machine centers are thus gradually achieved step by step within the scheduled cutting plan on the manufacturing site.
