As we are living in the era of smart manufacturing, industrial workers are more likely to pursue the work smart model rather than work hard. Because of the complicated machining process involved in metal processing, vertical machining centers with vertically arranged machining tools are popular on the market. This vertically arranged type machine contains strong vertical columns that could cope with various machining duties within a faster cycle time.
While the conventional milling centers may require more cycle time due to the lack of accessories for supportive purposes, the advanced vertical machining centers are much more applicable for complex machining duties and profiling cutting, rendering a good reputation in complicated processing. The CNC vertical machining centers can do way more than the conventional milling centers can do.
Although the cutting process of a vertical machining center is the same as all other machining centers, it is fundamentally different. The key issue is machining in the vertical direction. In addition to this function, the machining process of a vertical machining center is basically the same as using one or more rotating tools to cut the workpiece by advancing the tools to the workpiece on the same machine. The multi-machining capability ensures that the process can be performed in one station. Furthermore, having the multi-machining capability, the entire process can be completed well in different directions.
The tool turning ability is now also performed as a basic function on the machining center. The machining centers are also capable of dealing with a variety of parts which range from a smaller component to workpieces of large size. Advanced machining centers are a popular choice because they can provide accurate results and expected tolerance for the field operators and the customers.
The constant research and development of vertical machining centers are valued by private sectors and industrial product manufacturers since the increasing demand for finer yet more complicated products does not seem to end on the market. Once progress is made, the productivity of products can be enhanced and the profits can be significantly improved accordingly. It is hard for a traditional lathe to achieve the same effect.
Many industry insiders, as well as institutions and certification companies, have strongly proposed the following research and innovation ideas of the machining center. The term "machining center" can be used to refer to a variety of computer-based boring and milling machines equipped with several important but sometimes optional accessories.
The accessories that are incorporated together in a machining center include electric spindle, swing head, fourth table, high-end indexing table, movable tool, automatic particle changer, etc. Even if the above accessories are added to the machine, the vertical arrangement in this inventory will not change.
In addition to the vertical and horizontal phase alignment models of the tooling process, there are other classification methods in the machine center series that can be used to process machining operations, and in most processes, these two methods can still be recognized as basic classifications.
Because the machining tool moves in the vertical direction, the structure of the vertical machining center is basically easy to understand. Traditional milling centers and machining centers consist of at least three axes for machining, which is basically sufficient to cover most of the machining tasks described on the blueprint. However, the changes in the modern commercial market have led to changes in manufacturing and engineering. The modern commercial market now requires faster transportation and shorter delivery times, while requiring more varieties of the products. As a result, the large-scale but less flexible production model has become less preferable.
In order to meet the modern manufacturing requirements, besides the traditional uprights, electric spindles, basic boxes, spindle boxes, saddles, hydraulic units, and coolant pumps, the machining centers are also equipped with many supporting items such as automatic arm units, workpiece feeders, live tools Mechanisms, CMM equipment, rotary indexing tables, smart sensors, remote monitoring systems, and many other components. The listed parts are now considered the basic structural units of advanced machining centers.
There are three basic types of vertical machining centers: the swing head machining centers, the single-axis rotary table type, and the two-axis rotation index type. The swing head machining centers are capable of conducting multiple cutting tasks at all angles simultaneously.
The primary advantage of a vertical machining center is that it can handle heavy-duty machining tasks where large-scale workpieces are involved. Through the work of the clamping system, the large workpieces can be firmly secured on the worktable. With this advantage, many large-sized workpieces are transferred to the vertical machining center table for further processing, thereby improving work efficiency. In the future, it can be expected that CNC vertical machining centers will be further improved to make the machining processes even more advanced.
