When choosing a cnc machining manufacturer, we should pay more attention to the quality of the workpiece in addition to the price factor, because a good quality workpiece will be more durable and bring higher benefits. So, how to improve the quality of the workpiece when four-axis cnc machining?
1、Before four-axis cnc machining, it is recommended to use a calibration instrument to check whether the tool is operating within the allowed tolerance. Before machining, you should use the air gun to blow the tool head and locking nozzle clean, or wipe with a cloth to install the knife, otherwise there is a certain impact on the accuracy and quality.
2, four-axis cnc machining workpiece when the program list should be clear as a whole, including the model, name, program name, processing content, tool size, feed, especially the safety length of the tool holder, the margin reserved for each program and the indicator. To be clearly pointed out.
3、The list of CNC machining workpiece should be consistent with the direction of the reference angle indicated by the mold, and then check the upper 3D drawing, especially the workpiece that has been drilled to carry water, you must check whether the 3D drawing and the level on the workpiece are consistent.
4, before processing, must understand the contents of the CNC processing process, the process must be accompanied by 2D or 3D mapping, and must be marked " X length, Y width, Z height " six-sided data, which should be marked flat " Z " value, to facilitate the technical staff in processing After checking whether the data is correct, if there are tolerances, the tolerance data should be indicated.
5, reasonable use of four-axis cnc machining tools, should be careful to distinguish between steel and copper processing, the remaining amount of light knife is reasonable to ensure that the workpiece finish and tool life longer.
6, in the clamping process, please note the name and model of CNC machining workpiece and the program list is the same, whether the material size is matched, the clamping height is high enough, and the number of calipers used.
7、The speed of 4-axis cnc machining needs to be strictly controlled by technical operators, F speed and S spindle speed should be adjusted reasonably. f speed is fast, S spindle should be accelerated. The feed speed must be adjusted in different areas. After processing, check the quality without any problem, then you can finish the four-axis CNC machining process.
