CNC vertical drilling machines are suitable for batch processing of complex parts ｏｒ molds such as small and medium-sized plates, discs, and shells. The basic components of the machine tool are made of special cast iron and high stiffness structure. The guide rail is quenched and ground, and the matching guide rail is automatically lubricated intermittently with plastic, with stable feeding and no crawling, and good accuracy retention; The machine tool has cutting, high flow cooling, and wide chip removal slots; The system of Guangzhou CNC 980M is configured, and key components are tested using the American standard GLOBAL STATUS 7107 coordinate measuring machine. The positioning accuracy of the machine tool is tested using Renishaw dual frequency laser interferometer.
During the machining process ｏｒ after prolonged use, CNC vertical drilling machines may encounter some minor problems, such as thermal deformation caused by excessive temperature.
So, how to prevent thermal deformation during the operation of CNC vertical drilling machines? This involves the design of CNC vertical drilling machines. In order to reduce the thermal deformation problem of CNC vertical drilling machines, some measures should be taken during design. The internal heat of the machine tool is the primary heat source for thermal deformation, and the heat source should be removed from the main machine as much as possible. Nowadays, most electric motors of CNC vertical drilling machines The gearbox and hydraulic equipment are already external, and heat sources that cannot be separated from the host machine, such as spindle bearings, can reduce the internal heat generation of CNC milling machines.
The spindle component is a crucial component that directly affects machining accuracy, and the bearings on the spindle of CNC vertical drilling machines are generally a large internal heat source. In addition to using fine rolling bearings and oil mist smoothing on bearings, static pressure bearings can also be used on CNC vertical drilling machines, which are beneficial for reducing the temperature rise of the spindle of the CNC vertical drilling machine. In the spindle box of precision CNC vertical drilling machines, the use of conflicting clutches and other heating elements should be avoided as much as possible.
