CNC vertical lathe electrical system fault diagnosis methods to release time: 2015 - 11 - 10 clicks: 2658 efficient CNC vertical lathe, is suitable for machining medium and small dish, cover parts high strength cast iron base, column, has the good stability and seismic behavior of the vertical structure, the clamping workpiece is convenient, covers an area of small structure of oil-water separation, make the water clean environmental protection lasting separate cooling water tank, easy cleaning cartridge spindle structure of precision, high stiffness, easy to repair the spindle sleeve symmetry, hanging design, all the better to eliminate the influence of thermal deformation of machining accuracy high power ac spindle motor, to enhance the stability of the machine tool spindle adopts imported advanced grease lubrication, fully enclosed, saddle, pillar and maintenance-free guide overweight load is linear rolling guide, good dynamic response performance, high accuracy stable with high quality vertical electric tool post for 6 station, high rigidity and reliable tool change quickly, the centralized machine operation panel, make the operation more convenient, shortcut X/Z axis adopts the high precision ball screw and screw bearing, good accuracy stable protection, this product is fully closed environment clean. How do when nc vertical lathe electrical system malfunction diagnosis: 1, intuitive method in simple terms, is the use of the senses. Asked the breakdown field personnel carefully failure process, failure surface and failure consequences, and in the whole process of analysis is likely to be asked many times. 2, instrument control method using conventional electrical and instrument for each group, ac, dc power supply voltage of the dc and pulse signal is measured, for possible failure. Such as using a multimeter to check the power supply situation, and for certain sets of related signal status of points on a circuit board measurement, use oscilloscope to observe relevant pulse signal amplitude, phase, or even whether, with PLC programmer find the failure parts and causes in the PLC program etc. 3, nc vertical lathe signal hardware alarm and alarm indicator analysis indicates that means including CNC system, servo system, the various status of electronic, electrical devices and failure indicator, combining with indicator light state and the corresponding function that instructs the content may be revealed, and the cause of the problem and elimination method. More than four, interface state test of modern numerical control system will, in which PLC integration between the CNC and PLC is in the form of a series of interface signal communication connection each other. Some failures are related to the interface signal errors or missing, some of these interface signal can be in the corresponding interface board indicator light display and input/output board, some can be displayed on the CRT screen through simple operation, and all the interface signal can use PLC programmer callout. For each ac, dc power supply voltage of the dc and pulse signal is measured, for possible failure. 5, parameter adjustment method of nc vertical lathe numerical control system, PLC and servo drive system is set many parameters can be modified to adapt the demand of different machine, different working state. These parameters can not only make the electric system to match the specific machine tool, but also make the machine functions necessary to achieve optimal.
