Milling technology in precision CNC machining

In the field of machining industry, precision CNC parts processing is widely involved in the industry. Let’s take a look at CNC milling technology!

1. Feeding circuit of precision CNC milling plane parts: when milling plane mechanical parts, the side edge of end mill is usually used for cutting. In order to reduce the tool trace and ensure the appearance quality of the parts, the cutting in and cutting out procedures are carefully designed.
2. In the process of machining, when milling the surface, the cutting in and cutting out points of the cutter should cut in and cut out the surface of the part along the extension line of the part outline curve, instead of cutting directly into the part along the normal direction, so as to avoid scratches on the surface and ensure the lubrication of the part.
3. In the process of precision CNC machining and milling closing, if the curve of internal generalization is allowed to be extended, it should be cut in and out along the tangent direction. If the inner generalization curve does not allow extension, the cutter can only cut in and out along the normal direction of the inner generalization curve, and the cutting in and out points are selected at the intersection of two elements of the mechanical part generalization. When there is no intersection point of several internal elements, the cutting point should be far away from the corner in order to avoid the notch left at the general corner when the cutter compensation is withdrawn.

The above are the skills in the process of precision CNC milling, simple and complex precision parts processing, CNC milling technology will be different, according to the appropriate processing line.
