What are the main functional components of a vertical machining center machine tool?

According to the transmission structure, vertical machining centers are generally divided into gear-driven spindles, synchronous belt-driven spindles, direct-connected spindles and electric spindles. The transmission spindle can automatically switch between high and low gears according to the speed, has high rigidity, and is suitable for heavy cutting occasions. The speed is generally less than 6000 rpm. The synchronous belt shaft has a simple structure and strong buffering capacity. Overload sliding protection can effectively protect the spindle, and the speed is generally 6000-12000 rpm.
The direct spindle is a servo motor that directly drives the spindle through a coupling. It has high torque, low energy consumption, and a speed of 8000-15000 rpm. Common tools in the tool magazine of a vertical machining center include a cap-type tool magazine and a robot tool magazine. The tool change time of the cap-type tool magazine is greater than 8 seconds, and the tool change time of the robot tool magazine is greater than 4 seconds.
It only takes 2 seconds to add a center and replace tools, which is extremely efficient. An efficient vertical machining center will reduce machining time and simplify the production process, thereby shortening the manufacturing cycle and reducing production costs. Therefore, it is particularly important to consider this aspect when purchasing machine tools.
According to the structure, machining center machine tools can be divided into vertical machining centers, horizontal machining centers, gantry machining centers, etc.
