The anti-interference and elimination methods for Dongguan CNC machining center machines include: The CNC machining center has taken anti-interference measures such as shielding space electromagnetic radiation, absorbing impulse current, and filtering power clutter during design. It can to some extent prevent the influence of external interference sources on the CNC itself.
To ensure the stable operation of the CNC, it is necessary to take the following measures when installing and connecting the CNC:
1. To supply power to the CNC through the isolation transformer, the machine tool where the CNC is installed must be grounded, and the CNC and the driver must be connected to an independent grounding wire from the grounding point.
2. Suppression of interference: Connect the RC circuit in parallel at both ends of the AC coil, and install the RC circuit as close to the inductive load as possible; Reverse parallel connection of freewheeling diodes at both ends of the DC coil; Connect a surge absorber parallel to the winding end of the AC motor.
3. CNC machining centers should be kept away from equipment that generates interference, such as frequency converters, AC contactors, electrostatic generators, high-voltage generators, and segmented devices for power lines.
The outgoing cable of the CNC machining center machine adopts twisted and shielded cables or shielded cables. The shielding layer of the cable is grounded at a single end on the CNC side, and the signal line should be as short as possible. In order to reduce mutual interference between CNC signal cables and strong current cables, the wiring should follow the following principles:
Type of cable A: AC power cord, AC coil, AC contactor wiring requirements: Separate and bundle the cables of Group A with Group B and Group C, leaving a distance of at least 10CM between them, or conduct electromagnetic shielding on the cables of Group A.
