For the operation of CNC lathes, the installation and loading/unloading of cutting tools is one of the important steps. It not only affects the efficiency of the lathe, but also plays an important role in the accuracy of the lathe. For installing cutting tools, it is necessary to have rich experience and professional support to operate. Today, our CNC lathe manufacturer will explain the common clamping methods and their advantages and disadvantages for CNC lathe cutting tools.
a) Place the workpiece directly on the machine tool worktable or in machine attachments such as four jaw chucks and machine vises, and use a marking needle or indicator to accurately position the workpiece based on one or several surfaces before clamping it; b) First, perform the marking process for the machining surface position according to the processing requirements, and then align and compact according to the marked lines. One is to first complete the machining of the outer and inner holes, and then cut them using the m98 and m99 tuning programs. However, if there are only two, it is also similar to programming them again. Also, m98 can be used, m99，G50。 Call the subroutine twice in the main program, and after the subroutine completes one task, return the tool G50W34 (after adding the tool length and width to M99 subroutine, return to the main program G50W-64 and then return the tool M30).
In addition to the heart machine, subroutines can be used to complete processing, provided that there is a sufficiently long rod material. Alternatively, ending with M99 is also acceptable, but not recommended. 1、 Clamp the outer circle. Ordinary chucks (three jaw or four jaw) can be used, as well as pneumatic chucks and hydraulic chucks. You can also use cylindrical fixtures. 2、 Expand the inner hole. You can use a chuck or a specialized fixture. Manual, pneumatic, and hydraulic are all available. 3、 One top, one clip. 4、 Expand the inner hole and tighten it tightly. 5、 Two top-notch. 6、 Tighten it directly. (1) The clamping process is reliable and does not change the correct position occupied by the workpiece after positioning. (2) The appropriate clamping force should ensure that the position of the workpiece remains stable and the vibration is small during the machining process, while also preventing excessive clamping deformation of the workpiece. (3) Easy, convenient, labor-saving, and safe to operate. (4) Well structured.
The above is the commonly used clamping methods and their advantages and disadvantages for CNC lathe tools compiled and released by our CNC lathe manufacturer. We hope that the above explanation can be helpful for everyone when using CNC lathes in the future.
