The continuous improvement of the automation level of CNC machining centers and the development of their systems have expanded the scope of their processes. The modern CNC machining center* enables the workpiece to be clamped at one time to achieve continuous, efficient and high-precision machining of multiple surfaces, multiple features and multiple stations, that is, process concentration. However, a CNC machining center can only achieve good results under the right conditions.
Mainly suitable for workpieces in CNC machining centers
(1) Periodically repeat the workpieces that are put into production.
The market demand for some products is cyclical and seasonal. If a special production line is used, it will not be worth the loss. The processing efficiency of ordinary equipment is too low, and the quality is unstable, and the quantity is difficult to guarantee. And use CNC machining center, the first piece (batch) After the test is completed, the program and related production information can be retained. The next time the product is re-produced,production can be started with very little preparation time. CNC machining center working hours include preparation hours and machining hours. The CNC machining center distributes a long single-piece preparation time to each workpiece evenly, so that the average actual working time per production is reduced and the production cycle is greatly shortened.
(2) High precision workpieces.
Some workpieces have very little demand, but they are key components, requiring high precision and short construction period. It is necessary to use multiple machine tools to coordinate work with traditional processes. The cycle is long and the efficiency is low. In the long process flow, it is easy to produce waste products due to human influence. Caused major economic losses.
The CNC machining center is used for processing, and the production is completely controlled by the program. It avoids long process flow, reduces hardware investment and human interference, and has the characteristics of high production efficiency and stable quality.
(3) Mass production of work pieces.
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 to improve market competitiveness. The CNC machining center is suitable for small and medium batch production, especially for small batch production, when applying CNC machining centers. Try to make the batch larger than the economic batch to achieve good economic results. With the continuous development of CNC machining centers, the economic batch is getting smaller and smaller. For some complex work pieces, 5-10 pieces can be produced, and even CNC machining centers can be considered for single piece production.
(4) Multi-station and work pieces that can be concentrated in the process.
(5) A work piece with a complicated shape.
The application of four-axis linkage, five-axis linkage CNC machining center and the maturity and development of CAD/CAM technology have greatly improved the complexity of machining work pieces. The use of DNC makes the processing content of the same program sufficient for various processing needs,making automatic processing of complex work pieces easy.
(6) Work pieces that are difficult to measure.
