Series of lectures on maintenance and modification of CNC machine tools - Lecture 10

Second, 802 S / C machine tool CNC system maintenance and service At present, CNC machine tools have more and more into the SMEs, which gives the machine maintenance and service a lot of new problems, with 820 S / C machine tool CNC system Machine tools are no exception. The following are some of the experiences I have accumulated in my work, and I hope to help the maintenance service personnel. 1. Perfect random data Machine random data can be divided into three parts: “operational programming data”, “maintenance data” and “other data”. Whether the “operational programming data” is easy to understand and whether “maintenance data” is complete and effective will be directly

Centrifuge Test Tube

The advantage of the plastic centrifuge tube is that it is transparent or translucent, its hardness is small, and the gradient can be taken out by the puncture method. The disadvantage is that it is easy to deform, has poor corrosion resistance to organic solvents, and has a short service life.

Plastic Centrifuge Tubes have caps, which are used to prevent sample leakage, especially when used for radioactive or highly corrosive samples. It is very important to prevent sample leakage; the tube cap also has a function to prevent sample volatilization. And support the centrifuge tube to prevent deformation of the centrifuge tube. When choosing this point, you should also pay attention to check whether the tube cover is tight, and whether it can be tightly covered during the test, so as to achieve the inversion without leakage;
