Analysis of key points of machine tool maintenance in Japan Nakamura

　　When it comes to Japanese machine tools, people generally get the impression that they are very easy to use. What are the secrets of the easy-to-use Japanese Nakamura machine tool? Routine maintenance is important! The following editor will explain in detail the maintenance details and points of attention in the daily use of Nakamura machine tools in Japan.

　　Nakamura machine tool manufacturers: precautions before and after long-term deactivation

　　1. Using the specified type of grease, add grease to each axis, move each axis through the entire stroke so that the surfaces of the screws and guides are completely covered with grease, then stop the axes of the upper and lower turntables back to zero.

　　2. Regularly check the voltage of the CNC battery and zero memory battery of the machine tool. If the voltage is insufficient, please replace it in time. When the battery voltage is insufficient, the machine tool will report the BAT alarm.

　　3. Clean the iron filings inside the machine tool, clean the oil tank, clean the guide oil tank, refill the guide oil, check whether the machine tool hydraulic oil is deteriorated, check the spindle cooling oil, and regularly clean and replace it according to the cycle indicated in the machine tool maintenance manual.

　　4. After taking out the chip liquid in the cooling box, please consider the storage method of the cooling liquid (aspirate all the cooling liquid and confirm the pH value of the cooling liquid).

　　5. Clean each cooling fan and check whether there is oil pollution, so as to prevent the fan from turning to alarm after long-term shutdown.

　　6. Apply a layer of butter or WD40 to the upper tool rest, lower tool rest and inner metal sheet of the Nakamura machine to prevent rust.

　　7. Please drain the accumulated water in the moisture filter installed on the machine and close the main air valve.

　　8. Please put the desiccant in the electrical cabinet of the machine tool.

　　9. After completing the above operations, please press the emergency stop button and turn off the main power.

　　Nakamura stays as a manufacturer: Precautions when starting up after a long shutdown

　　Avoid starting a stopped machine at high speed immediately.

　　1. Check the input voltage before starting the machine, then start the machine.

　　2. Full stroke reprocessing for slow motion in automatic mode (over 15 minutes).

　　3. Carry out the running-in and running of the spindle, start from 100 rpm, slowly increase to a higher speed, and then slowly decrease to 100 rpm (during this running-in and running period, please run for more than 15 minutes).

　　4. Check whether the cooling exhaust fans installed inside and outside the spindle motor and control box work normally.

　　5. Check whether the oil level of each oil tank of the machine tool is normal.

　　6. After circulating the coolant in the machine, check the indicators of the coolant tank, such as concentration, ph value and whether it is deteriorated.

　　7. Confirm whether the level of Nakamura's machine tool meets the requirements. Check whether the machine tool accuracy is acceptable. When processing one piece, slowly confirm the coordinate position.

　　In the machine tool industry, as a "pioneer" of compound machining machine tools, based on the innovative technologies of machine tools such as precision CNC lathes and precision machining centers, we have deeply considered the development of new products and built a strong position.
