The running-in period of the multi-axis drilling machine is an important part to ensure the normal operation of the machine tool, reduce the defect rate and prolong its service life. However, at present, many users ignore the special skill requirements of the new machine running-in period because of the lack of common sense of multi-axis drilling machine tools or because of the tight schedule or the desire to get the benefits quickly. Some users even think that the manufacturer has a repair period, the machine is broken and repaired by the manufacturer. Therefore, the machine is overloaded for a long time during the running-in period, causing frequent premature machine problems, which not only affects the normal operation of the machine, but also shortens the machine. The service life of the machine, and also because the machine damage affects the progress of the project.
Therefore, we remind everyone that the application and maintenance of the multi-axis drilling machine running-in period should be given full attention. The specific aspects of attention are:
1. Many operational errors are caused by the understanding of the structure and function of the multi-axis drilling machine (especially the new operator), which is simple due to operational errors, and even causes mechanical accidents.
2. The appearance of leakage is caused by the looseness of the machine, the vibration of the machine and the heat of the machine. The sealing surface of the multi-axis drilling machine and the pipe joints will show the leakage appearance. Some forging and processing defects are difficult to find during installation and debugging. However, due to the oscillation and impact during the working process, this shortcoming is exposed, which is manifested as leakage (seepage) oil (water). Therefore, the running-in period is simply a leaky appearance.
3. The parts of the new processing and installation are loose, and there are deviations in geometric shape and cooperation scale. In the early stage of operation, due to the alternating load such as impact and oscillation, as well as the influence of heat, deformation and other factors, plus wear and tear, etc. Simple to loosen the parts that were originally tightened.
4. Slip poorness Because the cooperation gap of the newly installed components is small, and it is difficult to ensure the uniformity of the cooperation gap due to the installation, etc., the smooth oil (fat) does not easily form a uniform oil film on the conflict surface to resist the wear. Then the smoothing performance is reduced, which constitutes the abnormal wear of the machine in the early stage. In severe cases, it will constitute a fine cooperation in the appearance of conflicts on the surface of the scratch or bite, resulting in the onset of the disease.
5. The wear speed is fast because of the influence of the processing, installation and adjustment of the new multi-axis drilling machine. The conflict is rough and the contact area of ​​the cooperation surface is small, and the pressure on the surface is uneven. During the operation of the machine, the irregularities of the external parts of the parts are in conflict with each other, and the ground metal scraps continue to participate in the conflict as abrasives, which accelerates the wear and tear of the parts cooperation.
It can be seen that the wear of the components is simple and the wear speed is fast during the running-in period. At this time, if the work is overloaded, it may cause damage to the parts and cause problems in the early stage of the attack.

Optical Brighteners are important raw material in Detergent, Textile, Paper industries. DMS, CBS are mainly used for detergent field, such as: DMS is regarded as one of the perfect agent used in detergent industry, owing to introducing the morpholine group into the molecular, the properties such as acid and perborate resistance be improved. It can be used in the whitening of cellulose fiber, polymide fiber and fabrics, showing anionic characteres and has optical bule color, it has better resistance to chloride bleaching than VBL and 31#, the most favorable dyeing bath PH value is 7-10.
BA & BBU mainly are used for paper industry.
