Analysis of the problem that the CNC lathe can not change the cutter 1. The three-phase phase phase of the cutter head motor is reversed or the phase is missing, and the two lines of the cutter head motor are mutually adjusted or checked for external power supply 2. The positive rotation control information Tl + the outgoing terminal of the non transmission multimeter system of the CNC lathe system, measure the + 24V and Tl + contacts, and change the cutter manually together to see if the transmission voltage of these two points is + 24V, If the voltage does not exist, it is a system obstacle, which needs to be sent to the factory for repair or replacement of related IC components.
Analysis of the problem that the CNC lathe can not change the tool
The Tl + transmission of forward rotation control information of the system is normal, but there is open circuit in the control information loop or components are damaged. Check whether the forward rotation control information line is open circuit and whether the contact touch of this loop is excellent; Check whether the DC relay or talk touch device is damaged. 4. If the mechanism is stuck, the tool holder will roll by hand. If the tightness level is not stuck, disassemble the tool holder, adjust the mechanism and participate in the smooth liquid.
The machine caused by too long time of anti lock is stuck on the machine to loosen the tool holder, and then the system parameters are adjusted to maintain the tool holder. At the time of anti lock, the tool holder motor of CNC lathe is damaged. Dismantle the tool holder motor and roll it over to see if the motor is rolling. If it is not rolling, and if the circuit is OK, replace the tool holder motor and the tool holder motor with water to form the motor short-circuit drying motor, and add protection Good insulation measures.
No power supply for cutter head motor of CNC lathe check whether the power supply circuit of cutter head motor is open circuit, whether the contact is excellent, and whether the strong electrical components are damaged; Check whether the fuse is fused and the pull-up resistance is not connected. Connect the tool position input information with 2K pull-up resistance. If this resistance is not connected, the tool holder does not turn on the macro level. In essence, the behavior is to turn forward first and then turn immediately, so that the tool holder does not seem to move.
