数控系统的维护

Maintenance of numerical control system

1．严格遵守操作规程和日常维护制度；

1. strictly observe the operation rules and routine maintenance system.

2．防止灰尘进入数控装置内，漂浮的灰尘和金属粉末容易引起元器件间绝缘电阻下降，从而出现故障甚至损坏元器件；

2. to prevent dust from entering the numerical control device, the floating dust and metal powder can easily cause the insulation resistance between the components to decline, so as to fail or even damage the components.

3．定时清扫数控柜的散热通风系统；

3. to clear the cooling and ventilation system of the control cabinet.

4．经常监视数控系统的电网电压，电网电压范围在额定值的85%～110%；

4. the grid voltage of the numerical control system is constantly monitored, and the voltage range of the grid is 85% to 110% of the rated value.

5．定期更换存储器用电池；

5. regular replacement of storage battery;

6．数控系统长期不用时的维护：经常给数控系统通电或使数控钻床运行温机程序；

6. maintenance of CNC system for a long time: often to power the NC system or make CNC drilling machine running temperature program.

7．备用电路板的日常维护。

7. the daily maintenance of the standby circuit board.

机械部件的维护

Maintenance of mechanical parts

1．丝杠和导轨的维护：

1. maintenance of screw and guide rail:

①定期检查、调整丝杠螺母的轴向间隙，保证反向传动精度和轴向刚度；

Check and adjust the axial clearance of the screw nut regularly to ensure the accuracy and axial rigidity of the reverse transmission.

②定期检查丝杠支撑与床身的连接是否松动以及支撑轴承是否损坏。如有以上问题要及时紧固松动部位，更换支撑轴承；

Regularly check whether the connection between the screw support and the lathe is loose and whether the supporting bearing is damaged. If there are any problems mentioned above, fasten the loose parts and replace the supporting bearings in time.

③采用润滑脂的滚珠丝杠，每半年清洗一次丝杠上的旧油脂，更换新油脂。用润滑油润滑的滚珠丝杠，每天机床工作前加油一次；

3. Use grease ball screw, wash the old grease on the lead screw every half a year to replace the new grease. Lubricate the ball screw with lubricating oil, and fill it every day before working.

④注意避免硬质灰尘或切屑进入丝杠防护罩和工作过程中碰击防护罩，防护装置一有损坏要及时更换。

4. Pay attention to avoid hard dust or chip to enter the protective cover of the screw rod and bump into the protective cover during the working process.

2．主动轴的维护

2. maintenance of active axis

①定期调整主轴驱动带的松紧程度；

(1) adjusting the tightness of the spindle driving belt regularly;

②防止各种杂质进入油箱。每年更换一次润滑油；

To prevent all kinds of impurities from entering the tank. Replace the lubricating oil once a year.

③保持主轴与刀柄连接部位的清洁，需及时调整液压缸和活塞的位移量；

3. To keep the connection between the spindle and the hilt clean, we need to adjust the displacement of the hydraulic cylinder and piston in time.

④要及时调整配重。

(4) to adjust the weight in time.

对于机床，天博要用心定期维护保养，延长元器件的寿命和零部件的磨损周期，预防各种故障，才能提高数控钻床的平均无故障工作时间和使用寿命 。

For machine tools, we should maintain regular maintenance, prolong the life of components and the wear cycle of parts and spare parts, prevent all kinds of faults, so as to improve the average working time and service life of the NC drilling machine.
