The failure of the machine tool bearing will directly lead to the inability of the machine tool. Therefore, the failure of the bearing is very important for the machine. The bearing performance will directly affect the mechanical performance. Therefore, we must protect the use of bearings. What measures should we take for bearing failure? The author shares the following methods to avoid premature failure of machine tool bearings. In fact, what people usually call a pinhole camera does not use a pinhole lens. Pinhole lens refers to a lens that uses the principle of small hole imaging to obtain images. It is inexpensive and simple in principle, but its fatal weakness is that too little light passes through the small hole, resulting in too long exposure time. Taking photos with a pinhole lens in sunlight can take anywhere from a few minutes to a dozen minutes, especially when shooting at night with exposure times of up to several hours. Obviously, for a camera that shoots dozens to dozens of frames per second, it cannot meet the requirements. Pinhole lenses cannot be applied to cameras, so there is no "pinhole" camera in the strict sense. As is customary, a miniature camera using a fisheye lens, a flat lens or a conical lens is called a pinhole camera.

1. The axial clearance of the bearing in the machine tool is guaranteed. In order to avoid the influence of large axial pressure fluctuation of the bearing (greater than ±10%) and possible instantaneous instantaneous pressure, the numerical control equipment generally adopts special equipment axial pressure controller, etc. Instantaneous pressure disturbances that reduce axial pressure.
2, the development of bearing operating procedures in the use and management of CNC machine tool bearings, should develop a series of practical, effective operating procedures. For example, lubrication, maintenance, reasonable use and standardized bearing maintenance are the main contents of the use and management of numerical control equipment. Formulating and complying with operating procedures is one of the important measures to ensure the safe operation of CNC machine tools.
3. Maintenance of CNC machine tool bearings There are many types of CNC machine tool bearings. All kinds of CNC machine tool bearings have different characteristics due to their functions, structure and bearing components. The contents and rules of bearing maintenance also have their own characteristics. Specifically, according to the type of machine tool, bearing model and actual use, and with reference to the requirements of machine tool manual, the necessary bearing regular and grading maintenance system should be formulated and established.
According to the lens, the lens of the pinhole camera can be divided into three types: fisheye lens, flat lens and conical lens; according to the photosensitive element used, it can be divided into charge coupled element and complementary metal oxide semiconductor; According to the data transmission method, it can be divided into two categories: wireless cameras and wired cameras.
