How to distinguish 4 Axis and 5 Axis in machining centers?
Four axes: three axes plus a rotation axis, generally 360 ° rotation in the horizontal plane. But it cannot rotate at high speed.
Five axes: there is one more four axes. The rotation axis is generally 360 ° rotation of the vertical elevation, but it cannot rotate at high speed. This shaft is usually added to the upper and lower shafts, that is, the spindle. The five axes can be fully processed and can be clamped to make statues at one time.
Introduction:
CNC milling machine is a kind of automatic processing equipment developed on the basis of general milling machine. Their processing technology is basically the same, and their structure is also somewhat similar. CNC milling machines are divided into two categories: without tool magazine and with tool magazine. The CNC milling machine with tool magazine is also called machining center.
characteristic:
Parts processing has strong adaptability and flexibility, and can process parts with particularly complex contour shape or difficult to control size, such as mold parts, shell parts, etc;
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;
It can process parts that need to be processed in multiple processes after one-time clamping and positioning;
High machining precision, stable and reliable machining quality. The pulse equivalent of the numerical control device is generally 0.001mm, and the high-precision numerical control system can reach 0.1 μ m. In addition, NC machining also avoids the operator's mistakes;
High degree of production automation can reduce the labor intensity of operators. It is conducive to the automation of production management;
The production efficiency is high. Generally, the CNC milling machine 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 tools and adjusting tool data stored in the CNC device, which greatly shortens the production cycle. Secondly, the CNC milling machine has the functions of milling machine, boring machine and drilling machine, which makes the process highly centralized and greatly improves the production efficiency. In addition, the spindle speed and feed speed of CNC milling machine are stepless, so it is helpful to select the best cutting parameters;
