The grinding wheel carriage guide of the CNC machine tool adopts the cross-roller rigid guide, and the equipment adopts its semi-automatic feeding mechanism and its rotary cylinder. The tailstock shaft system of the equipment has the characteristics of gap-free rigidity. The electrical box, the hydraulic box cooling box and the machine tool Separation. The bearing of the grinding wheel spindle of the CNC machine tool effectively adopts its tapered shaped oil wedge dynamic pressure bearing. During the operation, the spindle of the grinding wheel still has high bearing stiffness at low speeds. The grinding wheel carriage guide adopts a cross-roller rigid guide. . Under normal circumstances, CNC machine tools will have a grinding indicator and a coolant filter to a certain extent. The headstock speed of the equipment has the AC frequency conversion stepless speed regulation. The electrical equipment of the entire equipment adopts a programmable program controller. It has a self-diagnosis function when in use.
The CNC machine tool can effectively check the screws. If they are loose, they need to be tightened in time, and the accessories should be cleaned to maintain cleanliness. The equipment needs to smooth the smooth parts. Pay attention to the smoothness in place during use. Ensure that the machine can operate normally. The CNC machine tool can effectively check the spindle hole, whether it needs to be adjusted during use, the feed organization and the longitudinal manual organization of the work table should be checked, whether there is any doubt, and how smooth it is. Check and clean the oil tank and filter to prevent the appearance of blockage.
The method often used in CNC machine tool control engineering is to first establish a simplified model that is as linear as possible, and then obtain the approximate characteristics of the system on this basis. If necessary, use more complex models for further research. This step-by-step approximate research method is a commonly used method in engineering. The mathematical model of CNC machine tool control system is not all rich control systems can adopt linearization processing methods. For some systems with strong nonlinearity, it is better to use nonlinear research methods to deal with them.
