Let's imagine what problems will occur if a machine is dark and humid, dusty, corroded by oil and various other chemical liquids, and if the production personnel move the machine without permission for a long time. It goes without saying that so many problems, not only the machining accuracy and performance of the machine will decline, the loss will greatly increase, and the replacement frequency of parts will soar, which will increase a lot of time and cost. Our precision machines will also be easily scrapped. So today we will summarize the matters that the probability will affect CNC processing, which can be avoided by reference to reduce the loss.
CNC parts processing
1、 CNC machining precautions:
Over cutting is a frequent problem, which should be paid special attention to. The most important review method is to make the tool path look like a mold, and repeat the inspection in the top view and side view. The tool path without review is not allowed to be machined. In profile milling, if the lower tool position is small, it will also cut too much, which can be avoided by changing the lower tool point.
2、 Mold tolerance for CNC processing precautions:
The accuracy of parts processed by CNC lathe is very strict. Only when the required accuracy is reached, can the accuracy be used. The main reason to judge the accuracy is its ability to control the size. If the accuracy is within the specified range of tolerance fluctuation, the parts are qualified. If the accuracy exceeds the tolerance, the parts are unqualified.

3、 CNC machining precautions for clamping tools:
Before the cutter head is installed on the machine, its taper fitting position should be wiped clean with a cleaning cloth. The tool length shall be adjusted by the tool tip (in special cases, the tool shall be adjusted in the middle of the tool), and the instructions in the program sheet shall be checked carefully. When the program is interrupted or the tool must be adjusted again, pay attention to whether the depth can be connected with the front. Generally, the line can be raised by 0.1mm first, and then adjusted according to the situation. If water-soluble cutting fluid is used for rotating retractable cutting head, it shall be immersed in lubricating oil for several hours every half month for maintenance.
