Precautions when CNC machine tools are shut down for a long time

Information may not be reliable

Good maintenance can make the machine tool machining accuracy maintain the best state, extend the service life, take the correct startup debugging way to CNC machine tools, in the face of new challenges, can show a good working state, improve production efficiency and processing effect.

Maintenance of NC machine tool stop

There are many kinds of CNC machine tools, which have different characteristics due to their different functions, structures and systems. The maintenance of the content and rules also have their own characteristics, specific should be based on the type of machine tool, model and the actual use of the situation, and refer to the machine tool use manual requirements, formulate and establish the necessary maintenance system. Here are some common maintenance tips.

1. Machine cleaning: clean up the workpieces, fixtures and iron filings in the machine, and clean up the iron filings in the external chip removing machine; The external sheet metal shall be wiped clean, and the electric control box air conditioner and oil cooler filter screen shall be cleaned.

2. Anti-rust treatment: Clean and wipe the workbench with anti-rust oil; The whole machine runs at a slow speed for one hour to lubricate the track. Whether the cutting fluid needs to be replaced, give priority to rust prevention, and add cutting fluid when the machine starts to need to work.

3. Complete the total power cut, gas cut and liquid supply in the workshop: run the Y-axis of the CNC machine tool to the middle, return the Z-axis to zero, and turn off the general electric switch of the machine tool, the transformer inlet switch and the air source, etc.

4. Waterproof and moisture-proof: Close the electrical box for protection.

Start - up debugging of CNC machine tools

CNC machine tool is a high technical content of electromechanical integration equipment, it is very critical to take the correct way to boot debugging, which largely determines whether the CNC machine tool can play a normal economic benefits and its own service life.

Check before starting: check the peripheral environment of the machine, whether there is abnormal phenomenon such as water in the electrical box and whether the oil deteriorates.

Boot: step by step in the voltage of power supply must test before starting the machine, must be in the power switch total about 10 min after the voltage stability, to open the machine power switch, other power switch and open the electric box, check whether the voltage is low, the lack of phase and in the absence of exceptional circumstances on machine tool power, and observe any abnormal phenomenon, have without leakage. When there is no alarm, do not perform any action and let the electrical components energize for 30 minutes.

Slow movement: Check whether there is interference, move the machine with the handwheel all the way, and pay attention to whether there is any abnormal phenomenon, and then perform the origin regression step.

Machine tool run-in: long time automatic running machine tool at slow speed and rotating spindle at low speed.
