Application scope of NC machine tool
NC machine tool is a programmable general processing equipment, but due to the high investment cost of equipment, it can not completely replace other types of equipment with NC machine tool. Therefore, the selection of NC machine tool has a certain scope of application. The figure can roughly show the scope of application of CNC machine tools. It can be seen from figure a that general machine tools are mostly suitable for occasions where the structure of parts is not too complex and the production batch is small; Special 13. Working environment: the machine tool used at room temperature ~ 45 ℃ is suitable for the production of large quantities of parts; CNC machine tools are also suitable for parts with complex shapes, although the batch size is small. With the popularity of numerical control machine tools, the scope of application of numerical control machine tools is becoming wider and wider. For some parts with less complex shapes and heavy repeated workload, such as the drilling processing of printed circuit boards, due to the high productivity of numerical control machine tools, they have also been widely used. Therefore, the application scope of CNC machine tools has been extended to the scope shown in the shadow in Figure a
figure B shows that when a general-purpose machine tool is used to load the sample; When the force measuring sensor is installed on the upper beam and processed by special machine tools and CNC machine tools, the relationship between the production batch of parts and the total processing cost of parts. According to relevant statistics, when the production batch is less than 100 and the parts with a certain degree of complexity are processed with CNC machine tools, the processing cost is the lowest and higher economic benefits can be obtained
figure application scope of CNC machine tools
it can be seen that CNC machine tools are most suitable for processing the following types of parts:
(1) producing parts in small batches (less than 100 pieces)
(2) the formability of spare parts made of plate and strip that need to be modified many times is twice that of high-strength low-alloy steel
(3) parts with high machining accuracy and complex structure and shape, such as box parts, curve and surface parts
(4) parts requiring precise reproduction and high dimensional consistency
(5) expensive parts. Although the production volume of such parts is small, if they are scrapped due to errors in processing,
will cause huge economic losses and return to the main page
