Common troubleshooting of CNC double disc grinding machine

CNC double disc grinding machine is widely used in mechanical manufacturing, optics and electronics, and has the characteristics of high precision, high efficiency and high repeatability. However, as with any mechanical device, this device can also experience some common failures. The following describes the troubleshooting methods of these common faults in detail.

一、The grinding surface is not smooth

Possible causes of failure include unbalance of grinding wheel, excessive spindle clearance, poor lubrication and so on. To solve such problems, first check whether the clearance of the spindle is too large, if the clearance is normal, you need to check whether the grinding wheel is balanced, and finally check whether the lubrication system is normal.

二、The grinding accuracy is not stable

The instability of grinding accuracy may be caused by the wear of the lead screw or guide rail, the loosening of the spindle, etc. For the wear of the lead screw or guide rail, regular maintenance and maintenance are required, such as applying grease. For the problem of spindle loosening, it is necessary to check whether the fixing screw of the spindle is tight and make necessary adjustments.

三、Abnormal grinding sound

Abnormal grinding sound may be caused by reasons such as uneven grinding wheel, bearing damage or gear wear. For such problems, it is necessary to check whether the grinding wheel is balanced, and then check the status of the bearing and gear, if there is damage, it should be replaced in time.

四、Cooling system failure

Cooling system faults include water cooling system, wind cooling system, etc. It may be caused by insufficient supply of cooling water or cooling air, and blocked filters. To solve such problems, it is necessary to check the flow rate and pressure of the cooling water, the flow rate and temperature of the cooling air, and the cleanliness of the filter, and clean or replace the filter in time.

五、Electrical system failure

Electrical system failures include power supply failures, control system failures, etc. It may be caused by poor contact of the power cable or fault of the sensor. To solve such problems, check the status of the power cables and sensors, and repair or replace the damaged parts in time.

In short, for the common troubleshooting of CNC double disc grinding machine, it is necessary to follow the principle from easy to difficult, and gradually investigate and solve the fault. At the same time, strengthening the daily maintenance and maintenance of equipment is also an important measure to avoid failure. By discovering and resolving faults in time, you can ensure the stable running of the device and improve production efficiency.
