Problems in the operation process of precision lapping and polishing machine
The key to precision grinding and polishing machine is to use a larger polishing speed to remove the hazard layer on the surface of the pipe fittings to ensure the purpose of polishing. The use of coarser metal composites can quickly remove the hazard layer, the use of finer metal composites, polishing the hazard layer shallow, but the polishing efficiency is generally lower.
Some consumers reflect that the use of precision grinding and polishing machine polishing two pipeline motor will make the hands hot. If the hand does not get hot during use, first determine whether the polishing machine is overloaded. If polishing a longer seamless steel pipe with a large, medium or small polishing machine, and there is no guide wheel for the fixed bracket, the frictional resistance of the seamless steel pipe moving forward will be great, thus increasing the operating load of the motor, and polishing two pipe motors will make the hands hot. Therefore, when polishing longer seamless steel pipes, a guide wheel must be installed on the fixed stand.
When grinding with a grinding wheel whose raw material is too soft, the surface of the workpiece of the commercial product will be uneven. If the surface of the seamless steel pipe burns, the grinding wheel must be checked for excessive compressive strength. From this, it can be seen that polishing wheels for precision grinding and polishing machines should be used with suitable compressive strength, excessively soft or solid polishing wheels.
In addition to the use of precision grinding and polishing machine, do not forget to do routine maintenance. Should pay attention to the following aspects:Polishing stainless steel plate work for a long time, metal composites and motors tend to heat up, so that the polishing machine before use to get a proper rest. Clear the dust on the motor in a timely manner, the motor heat dissipation mainly depends on the fan heat dissipation. If the dust is clogged, it will damage the heat discharged from the fan and cause the motor to burn the hands.
