What is CNC milling machining?

The machined surface shape of CNC milling parts are generally composed of straight lines, arcs or other curves. Ordinary CNC milling machine operators constantly change the relative position between the tool and the workpiece according to the requirements of the drawings., and then match the selected milling cutter speed, so that the tool can cut the workpiece and process a variety of different shapes of the workpiece.

CNC milling machining is to divide the motion coordinates of the tool and the workpiece into the smallest unit, that is, the minimum displacement. The numerical control system moves each coordinate by a minimum amount of displacement according to the requirements of the workpiece program, thereby realizing the relative movement of the tool and the workpiece to complete the machining of the part.

Besides the characteristics of ordinary milling machines, CNC milling also has the following features:

1. The parts are highly adaptable and flexible, and CNC machining center can process the parts with particularly complicated contour shapes or somes difficult to control dimensions, such as mold parts and shell parts;

2. CNC milling can process parts that cannot be processed or difficult to machining with ordinary machine tools, such as complex curve parts and three-dimensional space surface parts described by mathematical models;

3. Parts that can be processed in multiple processes after being placed in a single clamping position;

4. The processing precision is high and the processing quality is stable and reliable. The pulse equivalent of the numerical control device is generally 0.001mm, and the high-precision numerical control system can reach 0.1μm. In addition, the numerical control processing also avoids the operator’s operation error;

5, High degree of production automation can reduce the labor intensity of the operator and conducive to the automation of production management;

6. High production efficiency. CNC milling machines generally do not need special process equipment such as special fixtures. When replacing workpieces, it is only necessary to call the machining program, clamping tool and tool data stored in the numerical control device, thus greatly shortening the production. cycle. Secondly, the CNC milling machine has the functions of milling machine, boring machine and drilling machine, which makes the process highly concentrated and greatly improves the production efficiency. In addition, the spindle speed and feed speed of the CNC milling machine are infinitely variable, so it is beneficial to choose the best cutting amount.
