The X-axis stepping motor suddenly stops feeding, and the feedback signal is disordered. A factory-oriented economical CNC lathe that has been modified by the old lathe in the production process has a sudden stop feed of the X-axis stepper motor and feedback from the control panel. A faulty signal. Turn off all interference sources that can cause interference, and re-test the faults that have not been eliminated. Check the motherboard and there is no problem. Carefully check the "axis control section and find that it is because of the lateral motion motor (X-axis stepper motor) mounted on the carriage. When the machining tool holder is away from the workpiece, the shield will expose the X-axis stepper motor as the tool holder moves. Come out, causing the cutting fluid to wet the motor and infiltrate the cable plug. Dry and re-connect the cable, the test machine failure is eliminated. This is mainly because the Z-axis stepper motor has two cables, one is the power supply, one The root is the signal feedback. When the cable enters the water, the feedback signal is disordered, and the system will reflect it, resulting in machine failure.
2 <br> <br> prevention and maintenance of the electrical system refers to all electrical components and circuit connections, i.e. strong electric portion is generally referred to in addition to the CNC system and power. It includes buttons, switches, proximity switches, relays, solenoid valves, sensing components, etc., which are dispersed in various parts of the electric control cabinet and the machine body. In the case of large vibrations, heavy dust, and humid climate in the production site, electronic components, connecting wires, fuses, etc. of the electrical system are prone to poor contact, component damage, and fuse disconnection. This is the main reason for the frequent failure of the CNC machine tool electrical system. Therefore, careful prevention and maintenance must be carried out during use.
During the production process, the waterproof (oil) and dust-proof CNC machine tools are generally installed outside the processing area during the production process, but the execution components, detection components and related cables of the CNC system, such as servo motors, travel limit switches, The zero return switch is close to the processing area, and the coolant should not be opened too much during processing, causing the coolant to splash and wet it, causing machine faults: usually the numerical control device of the CNC machine tool adopts certain dustproof measures. However, the operating environment of the machine tool is different. If the environmental conditions are too bad, the oil mist and dust are serious. For example, when processing cast iron parts, it is necessary to add certain protection to the numerical control system, because the printed circuit board line inside the numerical control system chassis is very dense, processing When the dust that flies out falls on the printed circuit board, and the oil mist is added, it will be firmly attached to it, and over time, it will short-circuit with fire and cause a malfunction.
Regular maintenance and careful use of some CNC machine tools, the numerical control device is placed on the protective door, and the cable of the numerical control device of the switch protection door will be bent every time. For a long time, the cable or its joint part will be broken and connected. : Some CNC machine tools, the cable connected to the servo motor is exposed to the outside with the carriage, or dragged on other components, and the cable breakage is broken over time. Therefore, for CNC machine tools, it is necessary to regularly check and maintain, especially the cable, and find that there is a tendency of damage, breakage or virtual connection to replace it to prevent the occurrence of malfunction. Furthermore, the servo motor used in CNC machine tools is different from the ordinary motor. It is equipped with a pulse encoder and a position detector. It is a wearing part, especially the pulse encoder is glass, and it is bonded with epoxy resin. fragile. Therefore, for servo motors, do not use the hammer to knock when assembling: prohibit the collision of heavy objects such as parts and blanks or put them on top.

The installation of the countertop basin is easy, as long as the hole is opened on the countertop. There are a variety of sink edge designs for over-counter basin sink styles to choose from. It is necessary to ensure that the connection gap between the sink and the countertop is uniform, and there is no water seepage.
