Of system of control of strong report of numerical control machine tool safeguard with maintain

Numerical control machine tool is electric control a system besides CNC device (the servo that includes main shaft drive and feed drive) outside, still include machine tool strong report to control a system. System of control of machine tool strong report basically is by the drive of common AC motor and logic of machine tool electric equipment control equipment PLC reachs an operation dish wait for a part to form. Strong report of simple introduction machine tool controls what contactor of common afterwards report controls system and PLC to be able to make up Cheng controller in the system to safeguard here with maintain.
The maintenance of system of control of contactor of report of 1 common afterwards and maintain
   Numerical control machine tool besides CNC system, to machine tool of economy numerical control still contactor of common afterwards report controls a system. Its are safeguarded with maintain the job, basically be the problem that the strong electromagnetism of the contactor in how adopting measure to prevent strong report ark, relay disturbs. The interference source that the electromagnetism component such as the contactor in the strong report ark of numerical control machine tool, relay all is CNC system. Because communicate contactor, those who communicate electric machinery is frequent start, stop When stopping, phenomenon of its electromagnetism induction can make CNC system controls aiguille of the generation in circuit or wave to emerge wait for noise, disturb regular job of the system. Accordingly, must take step to these electromagnetism interference, give eliminate. For example, to communicating contactor coil, criterion the interference noise that in its two end or the three-phase input that communicate electric machinery carry shunt-wound RC network to restrain these electric equipment to arise. In addition, the oxidation that should notice to prevent contactor, relay to touch a head and the contact that touch a head are undesirable wait.
2 PLC can make up Cheng controller safeguard with maintain
   PLC can make up Cheng controller also is the important electric control part on numerical control machine tool. System of control of strong report of numerical control machine tool is controlled besides auxiliary to the machine tool motion and auxiliary movement outside, still include the control of all sorts of pair of protection switch, journeys and final limit switch. In afore-mentioned processes, PLC can write the electric equipment of system of strong report control is medium major machine tool on machine tool of Cheng controller replaceable numerical control, realize the pair of main shaft, logic that changes the system such as knife, lubricant, cooling, hydraulic pressure, pneumatic to control thereby. PLC can make up Cheng controller and numerical control device to close when be an organic whole, formed inside the PLC that fit pattern, and independent type PLC was formed when be located in beyond numerical control device. Because the structure of PLC forms the place that has likeness with numerical control device, so its are safeguarded with maintain can consult the maintenance of numerical control device and maintain.
