The necessity of precision parts machining in CNC machining!

2021/09/02



CNC lathe to achieve automation of small and medium batch processing and improve working conditions... In addition, it also has a series of advantages such as high productivity, stable machining accuracy and low product cost. In order to further play these advantages, CNC CNC lathe is to "process concentration", that is, a CNC CNC lathe in a clamping parts can be completed after multi-process processing CNC CNC lathe (i.e. machining center) aspects of development.


 

Drilling, boring, milling, turning and other single-function CNC lathe can only complete drilling, boring, milling, turning and other operations alone, while in the machinery manufacturing industry, most parts need multi-process processing... In the whole machining process of single-function CNC lathe, the time really used for cutting only accounts for about 30%, and most of the rest of the time is spent on auxiliary work such as mounting, adjusting tools, handling, loading and unloading parts and checking machining accuracy. In the case of parts need to carry out a variety of processes, single-function CNC lathe work efficiency is still not high... Machining center - generally has automatic tool change function, parts clamping can be completed after drilling, boring, milling, stop sinking, tapping and other processes.


1,Repeat production of the workpiece.
 The market demand of some products is cyclical and seasonal, if the use of special production lines is not worth obtaining, the use of ordinary equipment processing efficiency is too low, the quality is not stable, and the quantity is difficult to ensure. And use CNC machining center, after the first piece (batch) trial cut, you can keep the program and related production information, the next time to produce the product, as long as there is little preparation time to start production. CNC machining center work time includes preparation work time and machining work time... The CNC machining center distributes the very long single-piece machining work time equally to each workpiece, reducing the average actual work time for each production and greatly shortening the production cycle.

2, High precision workpiece
    Some workpieces need very little, but are critical parts, requiring high precision and short lead time, and the use of traditional processes using multiple lathes to coordinate work, its long cycle time, low efficiency, in the long process, it is easy to artificially influence the production of scrap, thus causing significant economic losses. And using CNC machining center for processing, the production is completely controlled automatically by the program. Avoid the long process flow, reduce the hardware investment and human interference, with high production efficiency and stable quality.

 

3, mass production of workpieces.
    The flexibility of CNC machining center production is not only reflected in the rapid response to special requirements, but also can quickly achieve mass production and improve market competitiveness. CNC machining center is suitable for small and medium-sized batch production, especially small batch production, in the application of CNC machining center. Efforts to make the batch larger than the economic batch, to achieve good economic results... With the continuous development of CNC machining center, the economic batch is getting smaller and smaller, for some complex workpieces, 5-10 pieces can be produced, and even single piece production can be considered when using CNC machining center.

5, the workpiece with complex shape

 

 Four-axis linkage, five-axis linkage CNC machining center applications, as well as the maturity and development of CAD / CAM technology, greatly improving the complexity of the workpiece processing . . the use of DNC so that the same program of processing content is sufficient to meet a variety of processing needs, so that the automatic processing of complex workpieces become easy to do.
