The cnc machining center should process according to the requirements and dimensions of the processing diagram, and ensure that the quality of the processed products is guaranteed. cnc machining centers are now widely used in various fields, mainly because the quality and size of the products processed by the machining centers are very standard. Then follow the small series to take a look at the precautions before cnc machining center processing.
First, cnc machining center before processing precautions
1, for the new mold, the processing drawing should meet the requirements, and the data is clear; The processing drawing of the new mold should be signed by the supervisor, and the fields of the processing drawing have been filled in.
2. The workpiece has the qualification mark of the quality Department.
3. After receiving the program, check whether the reference point of the workpiece is consistent with the reference point of the drawing.
4, see each requirement on the program list, confirm whether the program is consistent with the requirements of the drawing, if there is a problem, you must solve the problem with the programmer and the production team.
5, according to the material and size of the workpiece, judge the programmer to open the coarse or light knife program to choose the rationality of the tool, if found that the tool application is unreasonable, should immediately notify the programmer to make the corresponding changes in order to improve the processing efficiency and workpiece processing accuracy.
Second, machining center clamping tool precautions
1, the clamp should be installed firmly, not too short in the handle.
2, before each cable knife should check whether the tool meets the requirements, the length of the cable knife should be determined according to the processing depth indicated by the program, generally should be slightly longer than the processing depth value of 2mm and consider whether the tool handle collision.
3, in the case of deep processing depth, you can communicate with the programmer, as appropriate, the method of using two cable knives, that is, the first cable is half to 2/3 of the length, and then the cable is longer when it is processed to a deeper position, which can improve processing efficiency.
4, the use of extended cable nozzle, especially should understand the depth of the knife, the required knife length and other data.
5, before the tool head is installed on the machine, its taper matching position should be cleaned with a cleaning cloth, and the corresponding position of the tool sleeve of the machine tool should also be clean to avoid iron filings on the matching surface affecting the accuracy and damaging the machine.
6, usually the length of the tool using the tool tip to the tool (in special cases with the knife in the knife), the knife should be carefully checked the program instructions.
7, when the program is interrupted or re-run must be re-to the knife, should pay attention to whether the depth can be connected with the front, under normal circumstances can be adjusted first 0.1mm line, and then adjust according to the situation.
8, rotary retractable tool head, such as the use of water-soluble cutting fluid, should be used every half month with lubricating oil for a few hours for maintenance, can make the internal parts of the tool head lubrication without wear
