With CNC lathe needs to pay attention to details

CNC lathe appearance inspection before electricity, machine tool electrical inspection, opened the machine electric cabinet, check relay, contactor, fuse, servo motor, speed control unit socket, spindle motor speed control unit such as presence of loose socket, such as loose should recover normal, have connectors must lock lock, a connecting box machine must transfer to check box on the socket, loose connection with and without, is bound to lock locking arrangement. CNC electric box is checked, the door is open CNC electric, check all kinds of sockets interface, servo motor response line socket, spindle pulse generator outlet, manual pulse generator outlet, CRT socket and so on, if there are any loose to plug from the start, is bound to lock locking arrangement. Examining the printed circuit board according to the instructions on the setting of the short circuit of terminal, is bound to fit machine production factory set, really wrong should be set up from scratch, generally do not need to set up from scratch, but the user must keep the original records of the setting of short circuit terminal. Quality inspection to check all wiring terminals. Including the strong and weak electricity section when installing machine production factory wiring terminal and the motor power by terminal blocks, each terminal with a screwdriver fastening once, until with screwdriver twist fixed, the electrical socket is bound to tighten. All check electromagnetic valve, electromagnetic valve must advance with the hand several times, in order to prevent the bad action in the composition of the long time without electricity, if found abnormal, should be recorded, in case after electrify confessed to repair or replace. Limit switch to check all the limit switch action sensitive and examine whether the fixity, found adverse action or fixed not firm should be dealt with immediately. Button and check on the operation panel button and switch check, check all on the operation panel button, switch, indicator light wiring, found wrong should be dealt with immediately, check the CRT unit electric outlet and connect line. Ground inspection requires excellent ground, measuring machine ground, Ω grounding resistance is not greater than 1. Power phase sequence check with phase sequence table check input power phase sequence, confessed to the input power phase sequence and the power of the machine tool and calibration on phase sequence should be together for sure. Have a secondary wiring devices, such as power transformer, etc. , it is necessary to confess to the sequence of the secondary wiring of a gay. To ensure that the sequence of the land must be correct. This moment should be measuring voltage, well documented. Numerical control lathe on total voltage, through to total power machine, check the CNC electric box, spindle motor cooling fan, machine tool electrical box the turning of the cooling fan is correct, lubrication, hydraulic oil flag indicates the place such as lighting is normal and machine tool, the fuse is damaged, if there are any abnormal shall promptly blackout overhaul, no abnormal can proceed. Measurement of high-voltage electrical voltage of each part, especially for CNC and servo unit in the first level of power supply transformer voltage, and well documented. Check the oil, especially for the turret transposition, clamping, spindle gear shift, and the place such as chuck clamping hydraulic cylinder and solenoid valve. If there is any oil leakage power immediately repair or replace.
