Inspection of CNC lathe before use

1, CNC machine tool CNC electric box inspection

Open the door of the CNC electrical box, check all kinds of interface sockets, servo motor feedback line sockets, spindle pulse generator sockets, hand pulse generator sockets, CRT sockets, etc., if there is loose to plug again, lock the locking mechanism must be locked.

Check the setting of the short-circuit terminal on the printed circuit board according to the manual, and be sure to conform to the state set by the CNC machine tool factory. If there is any error, it should be reset. In general, there is no need to reset, but the user must make original records of the setting state of the short-circuit terminal. Wiring quality Check All wiring terminals. Including the terminals connected by the machine tool manufacturer during the assembly of strong and weak electric parts and the terminals of each motor power line, each terminal should be fastened once with a screw until it cannot be screwed with a screw, and each motor socket must be tightened.

2, CNC machine electrical inspection

Remind slant bed CNC lathe nc machine tools should be open the electric cabinet of machine before use, check the relay, contactor, fuse, servo motor, speed control unit socket, spindle motor speed control unit such as presence of loose socket, such as loose should return to normal state, a locking mechanism of connectors must lock, a connecting box transfer machine be sure to check box on the socket, Whether the wiring is loose, there is a locking mechanism must be locked.

3, CNC machine check the connection of all buttons, switches and indicators on the operation panel. If any error is found, it should be dealt with immediately. Check the socket and wiring on the CRT unit. Check the grounding cable. Check the grounding cable of the machine tool. The grounding resistance should not be greater than 1 Ohm. Check the phase sequence of the power supply. Check the phase sequence of the input power supply with the phase sequence table. Make sure that the phase sequence of the input power supply is absolutely consistent with the phase sequence of the power supply calibrated everywhere on the machine tool.

4, CNC machine solenoid valve inspection

All solenoid valves should be pushed several times by hand, in order to prevent the bad action caused by long time no electricity, such as abnormal, should be recorded, in order to confirm repair or replacement after electricity.

5, CNC machine limit switch inspection

Check all limit switch action flexible and fixed whether firm, found bad action or fixed should be dealt with immediately. Check buttons and switches on the operation panel,

6, CNC machine tools with secondary wiring equipment, such as power transformers, must confirm the consistency of the phase sequence of the secondary wiring. Make sure the phase sequence is absolutely correct. At this time, the power supply voltage should be measured and recorded.

The above is to bring you the inspection of CNC lathe before use.
