Precautions for CNC machining center processing

 When using CNC machining centers to process parts, the processing of details and the focus on technical points are related to processing efficiency and processing quality.

Therefore, we have several points to pay attention to in actual production:

  1. The choice of the cutting point: when programming the tool path, you can place the tool at any height and position specified. When the first tool is first processed, the amount of tool eaten is often relatively large, which is likely to cause the tool to break and snap the tool. The lower tool position is rough or the initial lower tool is empty. Try to cut out of the material. This problem must be paid attention to.
  2. Over-cutting inspection: Over-cutting is a frequent problem, which should be paid special attention to. The solution is to simulate the tool path again and check repeatedly in various azimuth angles. The tool path that is not checked is not allowed to be machined. When contour milling, over-cutting may occur if the lower tool point is selected improperly, which can be avoided by changing the lower tool point.
  3. Tool clamping length: refers to the length of the tool remaining outside the tool chuck after it is clamped by the chuck, and it should be installed as short as possible to improve rigidity without collision. Too long will swing and shake the knife.
  4. Before finishing milling, a smaller diameter cutter must be used to rough clear the corner margin. Where the corner cannot be cleaned, a curved surface should be used to block it to avoid excessive corner margin during fine milling and cause tool damage. The margin is uniform during finishing milling.
  5. Use the dry run function of the machine tool to check the correctness of the tool path. After the program is input to the machine tool, you can install the tool or workpiece, and then press the dry run button. At this time, the spindle does not rotate, and the worktable automatically runs according to the program path. At this time, you can find whether the tool may collide with the workpiece or fixture. However, in this case, it is necessary to ensure that the tool cannot be installed when the workpiece is installed; when the tool is installed, the workpiece cannot be installed, otherwise collisions will occur.
