No matter what type of CNC milling machine, the basic structure is composed of basic components, spindle components, CNC system, automatic tool change system, auxiliary system and automatic pallet exchange system.
Different CNC milling machines have their own technical parameters, but they are often most concerned by users, such as X, y, Z axis stroke (mm), worktable size x, y, Z (mm), maximum load of worktable (kg), spindle speed (R / min), magazine capacity (handle), x, y, Z axis rapid feed (M / min), x, y, Z axis positioning accuracy (mm), x, y, Z axis repeated positioning accuracy (mm) and CNC control system. Because these parameters are directly related to the brief understanding of the use performance of the NC milling machine, we can know whether it can basically meet the use requirements. Of course, for a detailed understanding, we also need the help of relevant instructions and coal transfer.
The rotation speed of the spindle of CNC milling machine is mostly variable, from tens of thousands of revolutions per minute to tens of thousands of revolutions per minute, so as to meet the needs of different processing. However, the conventional spindle speed is thousands of revolutions per minute. The emergence of high-speed cutting requires the speed of the spindle to be increased, which is generally more than 10000 R / min.
