CNC milling services surface shape is generally composed of straight lines, arcs or other curves.Ordinary milling operators according to the requirements of the drawings.Constantly change the relative position between the cutter and the workpiece, and then with the selected milling cutter speed, so that the cutter to the workpiece for cutting, can be processed into a variety of different shapes of the workpiece.
CNC milling services is the cutting tool and workpiece motion coordinates into the smallest unit, that is, the minimum displacement.According to the requirements of the workpiece program, the numerical control system makes each coordinate move a number of minimum displacement, so as to realize the relative motion of the cutter and the workpiece, and to complete the machining of parts.
CNC milling services in addition to ordinary milling features, there are the following features:
1. Parts processing adaptability, flexibility, can be processed contour shape is particularly complex or difficult to control the size of the parts, such as mold parts, shell parts;
2. It can process parts that cannot be processed or are difficult to be processed by ordinary milling, such as parts with complex curves described by mathematical model and parts with three-dimensional space surface;
3. The parts that need to be processed by multiple processes after one clamping positioning can be processed;
4. High processing accuracy, processing quality is stable and reliable, the pulse equivalent of CNC device is generally 0.001mm, high precision CNC system can be up to 0.1 micron, in addition, CNC milling services also avoid operating errors of the operator;
5. High degree of production automation, can reduce the labor intensity of the operator.Conducive to production management automation;
6. High production efficiency, CNC milling services generally do not need to use special fixture and other special process equipment, in the replacement of the workpiece only need to call the processing procedures stored in the CNC device, clamping tools and tool data can be adjusted, thus greatly reducing the production cycle.Secondly, CNC milling machine with milling machine, boring machine, drilling machine function, so that the process is highly concentrated, greatly improve the production efficiency.In addition, CNC milling services spindle speed and feed speed are infinitely variable, so it is conducive to the selection of the best cutting parameters.
