What are the precautions for CNC precision parts processing?

In the process of precision machining, there are many CNC machining processes that need to be mastered. These crafts are also a continuous learning process. Many friends have become independent experts from scratch. From the first day of entering this industry, you need to learn the precautions for CNC precision parts processing:

First, the choice of knife point is very important. In precision machining, a lot of tools are used and tools need to be changed frequently. When arranging the order of the knives, the selection of the first knife should be paid special attention. In order to avoid missing the knife, try to cut the knife outside the blank as much as possible, and you can choose any height and specified position. The first knife to go down is often more laborious. It is possible to break the knife or bounce the knife. It needs to accumulate experience to control it.

Second, emergency handling should be kept in mind. If the length of the tool clamping is too long, the diameter is too small, and the amount of feed is large, all kinds of emergencies such as dropping the knife, bouncing the knife, grabbing the knife, etc. must be known and handled flexibly. Especially in the case of grabbing the tool, it generally occurs when the machining radius is the same as the tool radius, and the external dimensions are inaccurate. You can use a knife with a small diameter, and then change a large knife to solve it step by step. If the depth is large, it must be processed in layers.

Third, the overcut check cannot be forgotten. Too much cutting is also common and must be avoided as much as possible. If the toolpath is simulated once, and the orientation of each toolpath is checked repeatedly, without this step, do not start precision machining. In the shape milling of CNC precision parts, if overcut occurs, the cutting point can be changed.

Of course, the employees who have just started the operation have a perceptual understanding of these CNC processing techniques and precautions. With the accumulation of experience, the rational understanding of CNC precision parts processing continues to deepen, and they can use them flexibly and cope with them easily.
