CNC Milling

CNC milling is a technology of computer-controlled (CNC) machining. It uses a cutter to remove material from a solid workpiece. The commonly used CNC milling machines in the industry are of two types:

●3-axis (X, Y, Z orientation)

●5-axis (X, Y, Z + A – rotational axis around X, B – rotational axis around Y)

In addition to the characteristics of ordinary milling machine processing, CNC milling processing has the following characteristic:

（1） Parts processing has strong adaptability and flexibility, and can process parts with particularly complex contours and shapes or difficult to control sizes, such as mold parts, shell parts, etc.;
（2） It can process parts that cannot be processed by ordinary machine tools or are difficult to process, such as complex curve parts described by mathematical models and three-dimensional space surface parts;
（3）It can process parts that need to be processed in multiple processes after one clamping and positioning;
（4） High processing precision and stable and reliable processing quality. 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 operating errors;
（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 machines generally do not need to use special process equipment such as special fixtures. When changing workpieces, it is only necessary to call the processing program, clamping tools and adjustment tool data stored in the CNC 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 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;
