CNC numerical control lathe work should pay attention to what requirements

Check the CNC numerical control lathe manufacturer of button and switch, check button on the operation panel and switch, and check all buttons on the operation panel, switch and lamp wiring, if found wrong, processing, and check the electric outlet and connect line. The CRT unit. Good ground checks for grounding, measuring machine grounding, grounding resistance Ω not greater than 1. Using the phase sequence table check the phase sequence of input power supply, and ensures the input power phase sequence and phase sequence of calibration on the whole machine power supply. With secondary connection device, such as power transformer, must confirm the sequence of the secondary connection of consistency. To ensure that the phase sequence is correct. At this point, measure and record the power voltage.

CNC numerical control lathe total voltage switch on, switch on machine tool power, check the CNC electric box, spindle motor cooling fan, machine tool electric cooling fan rotation is correct, lubrication, hydraulic oil marks indicating lights with a normal machine tool, the fuse is damaged, if there is any abnormal power outage immediately repair, no abnormal can continue. Measure and record all part of the voltage of electric current, especially CNC and servo unit in a power transformer voltage. Pay attention to the leakage situation, especially the cylinder and solenoid valve wheel rotation, clamping, main shaft movement and chuck clamping. One thousand the spill, shall promptly repair or replace the power supply.

CNC numerical control lathe factory inspection CNC lathe electrical box, the door is open CNC electric, check all kinds of interface socket, servo motor feedback line socket, spindle pulse generator outlet, hand pulse generator outlet, CRT socket to reconnect, such as loose have must be locking mechanism to lock. According to the description check each short circuit on the PCB terminal Settings. It must conform to the state of machine tool manufacturers set up.

if there is any error, should be reset. Check the connection quality. Check all the terminals. In machine tool factory of terminals and the terminal of the power line of each electric motor assembly, including parts of high voltage and low voltage parts, should use a screwdriver to each terminal clamp, until can't unscrew screwdriver, motor socket must be tightened. All solenoid valve solenoid valve check application hand push several times, in order to prevent the reactive power operation caused a power outage for a long time, such as abnormal should make records, to confirm without power after the repair or replacement. Limit switch fixed check check whether actions of all limit switches are flexible, in case of bad or fixed processing immediately.

CNC numerical control lathe on electricity before inspection, machine tool electrical inspection, open the electric cabinet of machine, check the relay, contactor, fuse, servo motor, speed control unit socket, spindle motor speed control unit, etc. If there's any loose outlet, due to the loose should be returned to normal, the connector of the locking mechanism must be locked, junction box machine must check box on the adapter socket, the availability of a loose connection must lock locking mechanism.
