System classification of CNC milling machine

① Cooling system. The cooling system of the machine tool is composed of a cooling pump, a water outlet pipe, a water return pipe, a switch and a nozzle. The cooling pump is installed in the inner cavity of the base of the machine tool. The nozzle sprays out to cool the cutting area.
②Lubrication system and method. The lubrication system is composed of manual lubricating oil pump, oil separator, throttle valve, oil pipe, etc. The machine tool adopts a periodic lubrication method, using a manual lubricating oil pump to lubricate the spindle sleeve, vertical and horizontal guide rails and three-way ball screw through an oil separator to improve the service life of the machine tool.
From the point of view of the characteristics of digital control technology, because the CNC machine tool adopts the servo motor, the application of digital technology realizes the direct control of the working sequence and movement displacement of the machine tool's executive parts. The gearbox structure of the traditional machine tool is cancelled or partially cancelled, so the mechanical structure is also Greatly simplified. Digital control also requires the mechanical system to have high transmission rigidity and no transmission gap to ensure the execution of control commands and the realization of control quality. At the same time, due to the continuous improvement of computer level and control ability, it has become possible to allow more functional components on the same machine tool to perform various auxiliary functions required at the same time. Therefore, the mechanical structure of CNC machine tools has higher integrated functions than traditional machine tools. Require.

From the perspective of the requirements of manufacturing technology development, with the emergence of new materials and new processes, as well as the low-cost requirements of market competition, metal cutting is moving towards higher cutting speeds and higher precision, higher and higher production efficiency and systems. Development in an increasingly reliable direction. This requires the CNC machine tools developed on the basis of traditional machine tools to have higher precision, more driving power, better dynamic and static stiffness and thermal stiffness of the mechanical mechanism, more reliable work, and can achieve long-term continuous operation and as little downtime as possible.
