In the field of modern machining, CNC machining centers play a very important role, not only to ensure the precision of parts cutting, but also to effectively improve the efficiency of parts processing, but also to better meet the processing needs of complex parts. When selecting the cutting parameters of CNC machining center, it is necessary to carry out the three aspects of cutting depth, cutting speed and cutting feed to ensure the rationality of cutting parameters selection and further improve the cutting ability of CNC machining center. The following Kunshan Duyang CNC from these three aspects to share with you. 1. Selection of cutting depth Cutting depth is a very important factor in the control of CNC machining center cutting parameters, only in the process of cutting to ensure that the cutting depth is within a reasonable range, can ensure that the processing size to meet the actual machining accuracy needs, and on this basis to further improve the machining accuracy and efficiency of CNC machining center. In other words, in the use of CNC machining center for parts processing, to use the least amount of cutting as much as possible to complete the cutting, thereby shortening the cutting time, improve the cutting speed, in order to achieve this goal, it is necessary to choose a reasonable cutting depth, while taking into account the cutting performance of the tool. Therefore, in the use of CNC machining center for cutting, in order to improve the accuracy of parts processing, to ensure the surface roughness of parts, it is necessary to reasonably control the depth of cutting, on the basis of ensuring the size and accuracy of parts processing, to improve the efficiency of parts cutting processing as much as possible. 2. Selection of cutting speed Cutting speed is another very important parameter in the machining process of CNC machining center, reasonable cutting speed is not only conducive to ensuring the quality and efficiency of parts processing, but also can well reduce the degree of tool wear, improve the economy of cutting machining, so in the actual use of CNC machining center cutting process, should be reasonable control of cutting speed, Further improve the CNC production speed. In the process of CNC cutting, the actual cutting speed has an inevitable relationship with the material of the parts, in the cutting process, only to ensure that the set cutting speed matches the material properties of the parts, can effectively improve the cutting speed of the parts, and ensure that the finished parts meet the standard requirements. In addition, when selecting the cutting speed of the CNC machining center, it is also necessary to take into account the machining performance of the machine tool, often the same parts to be machined, the same cutting tool, and the cutting speed required by different machine tools are greatly different. 3. Selection of cutting feed The rationality of the selection of cutting feed is directly related to the speed and quality of cutting, so in the actual cutting process of the CNC machining center, it is necessary to strengthen the control of the cutting feed, only to ensure that it is in the standard range, can be a good guarantee of the quality of cutting, to ensure that the processing size meets the actual drawing requirements. In general, the determination of the cutting feed needs to be selected according to the material of the parts to be cut. When the roughness of the machined surface of the parts in the drawing is not high, the cutting feed can be appropriately improved during cutting, when the roughness of the machined surface of the parts is higher, it is necessary to reduce the cutting feed to ensure that the surface roughness of the machining meets the requirements of the drawing. When controlling the feed rate of the CNC machining center, it is also necessary to connect with the cutting depth and cutting speed, and rationally select these three cutting parameters to effectively improve the production level of the CNC machining center.
