Daily maintenance of advertising engraving machine

(1) Strictly abide by the operating procedures and daily maintenance system CNC equipment operators should strictly abide by the operating procedures and daily maintenance system, the quality of the operator's technical business is an important factor affecting the frequency of failure. When the machine tool fails, the operator should pay attention to keep the scene, and tell the maintenance personnel the situation before and after the failure, so as to facilitate the analysis and diagnosis of the cause of the failure and timely elimination. 

(2) To prevent dust and dirt from entering the CNC device in the air of the machining workshop, there will generally be oil mist, dust and even metal powder, once they fall on the circuit board or electronic devices in the CNC system, it is easy to cause the insulation resistance between the components to decline, and even lead to damage to the components and circuit boards. Some users in the summer in order to make the CNC system can overload long-term work, take to open the door of the CNC cabinet to dissipate heat, this is a highly undesirable method, which will eventually lead to the acceleration of the CNC system damage, should be minimized to open the CNC cabinet and strong current cabinet doors. (3) To prevent the system from overheating, it is necessary to check whether the various cooling fans on the CNC cabinet work normally. Check whether the air duct filter is blocked every half a year or every quarter. If the dust accumulation on the filter net is too much and it is not cleaned up in time, the temperature in the CNC cabinet will be too high. Maintenance of mechanical parts. a. Maintenance of ball screw thread pair regularly check and adjust the axial clearance of screw thread pair to ensure reverse transmission accuracy and axial stiffness; Regularly check whether the connection between the lead screw and the bed is loose; The lead screw protection device should be replaced in time to prevent dust or chips from entering. b. The maintenance of the main drive chain regularly adjusts the tightness of the spindle drive belt to prevent the loss of rotation caused by the slip of the belt; Check the constant temperature tank of the spindle lubrication, adjust the temperature range, replenish the oil in time, and clean the filter; After the tool clamping device in the spindle is used for a long time, there will be a gap, which affects the clamping of the tool, and the displacement of the hydraulic cylinder piston should be adjusted in time. Maintenance of machine tool accuracy Check and correct machine tool level and mechanical accuracy regularly. There are two kinds of correction methods for mechanical accuracy: soft and hard. The soft method is mainly through the system parameter compensation, such as lead screw reverse gap compensation, coordinate positioning accuracy fixed point compensation, machine tool back reference point position correction, etc. The hard method is generally carried out during the overhaul of the machine tool, such as the guide rail repair, the ball screw nut pair pre-tightening to adjust the reverse clearance.
