What is cnc turning center?
Conventional economical CNC lathes have two axes, X and Z. Turning center have many axes, 3 axes, 4 axes, 5 axes, and so on. In addition to the function of turning and milling, it has the function of high efficiency. The clamping times and time are reduced.
To sum up, the CNC turning center has the following characteristics:
(1) Strong adaptability, suitable for the processing of multi-variety and small-batch parts.
In the traditional automatic or semi-automatic lathe processing a new part, generally need to adjust the machine tool or machine tool accessories, in order to make it easy to use.
The machine tool adapts to the requirements of processing parts, while when using a CNC lathe to process parts of different shapes, it only needs to reprogram or modify the machining process
The program (software) can quickly meet the processing requirements and greatly shorten the technical preparation time for replacing the machine hardware
Suitable for multi-variety, single piece, or small-batch processing.
(2) High machining accuracy and good consistency
Because of the integration of high and new technologies such as machine and electricity, the machining accuracy of CNC machine tools is generally higher than that of ordinary machine tools. Development of CNC machine tools.
The machining process is controlled by the computer according to the pre input program, which avoids the poor technical level of the operator.
The difference in product quality caused by differences. For some workpieces with complex shapes, it is almost impossible for ordinary machine tools to complete them.
But the CNC machine tool only compiles the more complex program to be possible to achieve the goal, when necessary also may use the computer-aided programming or the computer to calculate
Computer-aided processing. In addition, the machining process of the CNC machine tool is not affected by the physical and emotional changes of the operator.
(3) It has higher productivity and lower processing cost
The productivity of machine tool mainly refers to the time needed to process a part, including the time of maneuver and auxiliary time. number
The spindle speed and feed speed of the lathe can be controlled in a wide range, and stepless speed regulation can be adopted. The best cutting speed can be selected during machining.
In order to optimize the cutting parameters, productivity is greatly improved,
The processing cost is reduced, especially for the parts of mass production, the larger the batch, the lower the processing cost.
For mass production, especially mass production, processing efficiency and efficiency should be emphasized on the premise of ensuring processing quality
The stability of the process, its processing technology and the single small batch is different. For example, fixture selection, tool path arrangement, and tool arrangement
The location and order of use should be carefully considered, and the relevant contents will be introduced in the next section.
The opposite of mass production is single-piece production. The most important feature of single-piece production is to ensure the first pass rate, especially the one-off quality.
Parts with complex shapes and high precision requirements. Second, compared with the success rate of single-piece production. Single-piece production
The NC process used is different from mass production in the aspects of tool path, tool arrangement, and tool change point setting. And batch production
Compared with production, single-piece production should avoid too long production preparation time.
