The basic components of a CNC machine tool include a machining program carrier, a numerical control device, a servo drive device, a machine tool body and other auxiliary devices. The following are the basic principles of the various components of a brief description. Most CNC machine tool failures due to power failure, and a lot of power failure is caused by damage to machine tools.
Reason Analysis of CNC Machine Power Failure
1, CNC machine power
CNC machine tools used by the power can be divided into three levels, from a power supply to the three power supply followed by a derivative of the relationship between the frequency of its failure and the difficulty also increased.
2, CNC machine tool power circuit components
CNC machine tools from a power supply to three times the use of power devices are:
(1) Workshop power distribution equipment, generally including: three-phase AC voltage regulators and circuit breakers connected to the plant grid.
(2) machine tool components, including: reactor, circuit breakers, filters, rectifiers, three-phase AC transformers, fuses, DC / DC modules, servo power components and switching power supply
