浅谈数控机床的维护保养与故障排除（Discussion on maintenance and troubleshooting of CNC machine tools） [Abstract] CNC machine is a high precision automation equipment, the price is expensive, in order to ensure the smooth operation of long-term security machine, to play a greater benefit, the need to focus on CNC machine tool maintenance method and prone to failure and troubleshooting. Introduction In recent years, CNC machine tools are widely used in manufacturing, the key equipment of enterprise production, brings great benefits; however, the complexity and advanced intelligent CNC machine tool of high characteristics, also make CNC machine maintenance work required, types of failure are increased, it is difficult to diagnose. 1 use CNC machine tools reasonably 1.1 CNC machine tools work site selection (1) avoid direct sunlight and other heat radiation and avoid too much tide Wet or dust excessive place, as far as possible in the air-conditioned environment, keep at room temperature about 20 degrees celsius. Because our country is in the temperate zone climate, is affected by the monsoon, the temperature The degree of difference is great, and the numerical control machine tools with high accuracy and high price should be used in air-conditioned rooms. (2) to avoid corrosive gas. because Corrosive gases tend to deteriorate electronic components or cause poor contact or cause Component short circuit, affect the normal operation of the machine. (3) keep away from vibration equipment (such as punch press, forging press, etc.). For high precision machine tools, anti vibration measures should be adopted (such as vibration proof ditch, etc.). (4) to keep away from strong electromagnetic interference sources Machine tool work stability. 1.2 power supply of CNC machine tools The numerical control system is more strict to the power supply, the general request work voltage is 220V + 10%. In view of the power supply situation in our country, for the qualified enterprises In order to reduce the
