Several small details to pay attention to in the process of polishing
In view of the polishing process need to pay attention to what, what need to pay attention to the small details:
1, micro powder suspension is added, so that the polishing machine polishing fabric to maintain a certain humidity.
2, polishing objects or stop rotation, in order to avoid the local wear of polishing fabric is too fast, can rotate and move back and forth along the radius direction, to achieve a better polishing effect!
3, the intensity of the need to grasp the polishing, to prevent the pressure is too large to produce a new grinding marks;
4, polishing objects to be fixed, to prevent the specimen from flying out of wounding;
In the use of polishing machine for polishing, in order to take a better polishing effect, polishing the humidity also need to continue to grasp:
1, in the process of friction will heat and humidity is too small, may lead to high temperature of a polishing article, reduced lubrication, grinding to lose luster, and even spots!
2, if the humidity is too high, the sample in hard phase showed embossed and steel in non graphite in cast iron and metallic inclusions produce "trailing" phenomenon, will weaken the polishing wear scar.
