Machining center, also called CNC milling machine, is an automatic processing equipment developed on the basis of general milling machine. Simply put, it is a milling machine equipped with a computer operating system. The processing technology of the two is basically the same, and the structure is somewhat similar. In addition to the features of ordinary milling machines, the machining center also has the following features:
1. The parts have strong adaptability and flexibility, and can process parts with particularly complex contour shapes or difficult to control size, such as mold parts, shell parts, etc.;
2. It can process parts that cannot be processed or difficult to process by ordinary machine tools, 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. The processing accuracy 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 errors;
5. The high degree of production automation can reduce the labor intensity of the operator. Conducive to the automation of production management;
6. The production efficiency is high. The CNC milling machine generally does not need to use special process equipment such as special fixtures. When replacing the workpiece, it only needs to call the processing program, clamping tool and adjustment tool data stored in the CNC device, thus greatly shortening the production. cycle. Secondly, the CNC milling machine has the functions of a milling machine, a boring machine, and a 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 continuously variable, which is conducive to selecting the best cutting parameters; this machining center is widely used in various fields of mold processing and manufacturing.
How much can I buy a machining center? This question is a matter of comparison. But this question is really difficult to answer, because every customer's needs are different. What are the factors that affect the price of processing centers? The Weimeng editor summarizes the following points.
Number of axes: three axes, four axes, five axes and even multiple axes.
Stroke: mainly depends on the size of the processed parts.
System: It is equivalent to the brain of a processing center. Japan's FANUC and Mitsubishi are both good choices.
Tool magazine: The tools used on the CNC milling machine should be selected according to the information, geometry, surface quality requirements, heat treatment status, cutting efficiency and machining allowance of the processed parts, and choose the tools with good rigidity and high durability. Common tool magazines include hat type tool magazine, knife arm type tool magazine and disc type tool magazine.
Manufacturer: Choosing a good machining center manufacturer is an important part of purchasing a machining center. We, Weimeng CNC focus on quality from the source, adopt Taiwanese technology, and have perfect after-sales service. If you have a need for machining centers, welcome to contact us, Weimeng CNC will serve you wholeheartedly.
