With the rapid development of China's economy, the pace of development of military industrial enterprises has also accelerated, and gradually move toward marketization. The characteristics of military industrial enterprises are high-tech and high-tech, and Aoyu Kexin has also demonstrated its glory in military industrial enterprises with its innovative "Ao Ke" technology.
A military factory in Wuhan is a large state-owned military enterprise. As a company producing military products, the process standards, precision requirements and structural requirements of the products in the production process are very strict or even demanding. The machine tool for producing and processing military equipment is the latest and most accurate machine tool equipment in the country. However, due to long-term use, oil corrosion and air oxidation and mechanical friction, there are uneven pores, sand holes and grooves on the guide surface. . The function of the machine guide rail is to guide and support. Its accuracy, rigidity and structural form have a direct impact on the machining accuracy and load carrying capacity of the machine tool. In order to ensure the high precision of machining and large bearing capacity of CNC machine tools, the guide rails are required to have high guiding precision, sufficient rigidity, good wear resistance and good low-speed motion stability.
If there are blisters or scratches on the surface of the guide rail, it will mean that the accuracy of the parts produced by the machine is greatly reduced, and the smoothness and load carrying capacity of the guide surface will be seriously affected.
When the leader of the military industry learned that Aoyu Kexin Wuhan Branch had the possibility of repairing the repair technology of the machine tool guide, he dubly invited the branch manager to the site to discuss. Based on the experience of “Oke†technology repair in recent years, the manager of Wuhan Branch believes that it is completely sure to repair the machine guide rails and decisively took over the business.
In this repair, the Wuhan branch decided to use the normal temperature cold-melting technology to effectively fill the groove and the wear surface first, and to repair the smoothness and flatness of the guide surface by using Ouyu Kexin inverter pulse brush plating technology.
In the repair process, because the surface finish of the guide rail is very high, and there is also a high requirement in hardness and precision, Aoyu Kexin Branch has selected a material with high wear resistance for welding to improve the hardness of the machine guide rail. In addition, the hardness of this kind of filler can be consistent with the hardness value of the machine guide surface itself, and achieve good wear resistance. For the requirements of finish and precision, Aoyu Kexin uses the inverter pulse brush plating technology to repair the repair surface of the guide rail. The brush plating metal plating solution developed by Aoyu Kexin has high bonding strength and good resistance. Grindability, fine crystals, can be used for repairing general precision parts.
Because the precision of the machine tool guide itself is high, the technicians of the branch company use the special measuring tools to measure the exact difference before each repair. In the pretreatment, a chemical solvent degreasing method is also used for degreasing. After the repaired post-processing, the manufacturer's required repaired rail surface is consistent with the datum smoothness and finish. Therefore, the branch technicians use the manual grinding method and the grinding edge measurement method to grind the repair surface. Accuracy reaches a tolerance of 2 filaments above and below the reference value. Therefore, in this repair, it can be said that the most advanced application technology of Aoyuxin is adopted from both the repairing material and the technical process.
The completion of this repair work marks that Aoyuxin's repair technology has entered a mature stage for repairing large-scale precision guide rails, and has entered a new level for repairing precision parts.
