What’s CNC Machining Center?
CNC-machining-center-chinaCNC machining center is a machine with tool magazine and can change tools automatically. At a certain range, CNC machining center can work on a workpiece with multi machining process.
The characteristics of the processing in the processing center on the part is machined parts through a clamping, the CNC system can control the machine automatic selection and replacement of cutting tools according to different processes; automatically change the trajectory of the spindle speed, feed rate and tool relative to the workpiece and other auxiliary functions, continuously machine the surface of workpiece automatically for drilling, counterboring, reaming, boring, tapping, milling and other machining processes. The machining center can focus on the completion of a variety of processes and automatically, to avoid the artificial operation error and reduce the workpiece clamping, measurement and adjustment of machine tool and workpiece turnover, handling and storage time, greatly improves the machining efficiency and precision, so it has good economic benefits. Machining center according to the location of the spindle can be divided into vertical machining center and horizontal machining center.
CNC machining center is composed of mechanical equipment and CNC system for the processing of complex parts of the high efficiency of automatic machine tools. CNC machining center is the world’s highest yield, the most widely used one of the CNC machine tools. It’s comprehensive processing ability, clamping a workpiece can be completed after processing more content, high machining accuracy, difficulty to medium batch processing jobs, and its efficiency is the common equipment 5 to 10 times, especially it can be completed many common processing equipment can not be completed, to more complex shapes, high requirements the accuracy of single processing or small batch production of many varieties is more suitable.
CNC machining center is a function of the CNC machine tools. It has the functions of milling, boring, drilling, tapping thread and cutting thread, and so on. It has a variety of techniques. The machining center is provided with a cutter base, and a different number of tools or tools are stored in the tool magazine, and the process is automatically selected and replaced by the program. This is the main difference between it and CNC milling machine, CNC boring machine. In particular, to ensure the quality and efficiency of the workpiece, the workpiece must be used to ensure the quality and efficiency of the product. This will be for new product development and modification and updating to save a lot of time and cost, so that the enterprise with strong competition ability.
Machining center is from the development of CNC milling machine. The biggest difference is that with CNC milling machining center has the ability to automatically exchange tool, through the tool installation for different purposes in the knife storehouse, be in a fixture through the automatic tool change device to change the tool spindle, to achieve a variety of processing function.
Processing center from the appearance can be divided into vertical, horizontal and composite processing center, etc.. The main shaft of the vertical machining center is perpendicular to the working table, which is mainly suitable for processing the sheet metal and the shell type work piece, and can also be used for the mold processing. Horizontal machining center spindle and the worktable parallel worktable, it mostly by the NC rotary table servo motor control, in a clamping workpiece, by rotating the worktable can realize the processing of a plurality of processing surface, suitable for processing box type parts. Composite processing center mainly refers to a processing center on the vertical and horizontal two spindle or spindle can change the angle of 90 degrees, so the workpiece can be a fixture in the realization of the five surface processing.
