Precision hardware parts in the actual work of the strength and toughness requirements are relatively high, its performance and service life and its surface performance has a great connection, and the improvement of surface performance, can not simply rely on materials to do, is also very uneconomic practice, but the actual processing must make its performance meet the standard, at this time need to use surface treatment technology In recent years, this technology has been developed rapidly. In the field of mold surface treatment, mold polishing technology is a very important link, and also an important process in the process of workpiece processing. The surface treatment process of precision hardware parts is very important in the processing process, so what are the surface treatment processes of precision hardware parts?

It is worth reminding that the polishing of the mold surface of precision parts is not only affected by the technological process and polishing equipment, but also by the specularity of the part materials, which has not been paid enough attention in the current processing, which also means that the polishing itself is affected by the materials. Although the processing technology to improve the surface properties of precision parts is constantly upgraded, the most widely used technology in precision parts processing is hardening film deposition, nitriding and carburizing.

Because the nitriding technology can obtain a high level of surface properties, and the nitriding technology process has a very high consistency with the quenching process of steel in precision parts, and the nitriding temperature is very low, so after the nitriding technology treatment, there is no need for intense cooling process, so the deformation of precision parts will be very small, so the nitriding technology is the same It is one of the earliest technologies used to strengthen the surface properties of precision parts, and it is also the most widely used technology at present.

The precision of hardware parts almost determines the quality of products. The more precise the hardware parts are, the higher the precision requirements will be. So why does the precision of hardware parts become worse? Let's take a look at it.

The first factor is the poor machining accuracy of the parts. Generally speaking, if the dynamic error between shafts is not adjusted properly during installation, or because the shaft transmission chain changes due to wear, the accuracy of the parts will be affected. Generally speaking, the accuracy caused by this type of error can be solved by readjusting the compensation. If the error is too large, even if an alarm is generated, it is necessary to check the servo motor to see if its speed is too high.

The second factor is that when the machine tool is running, the overshoot will also affect the machining accuracy. It may be because the acceleration and deceleration time is too short and the change time is appropriately extended. Of course, it is also very likely that the link between the lead screw and the servo motor is loose.

The third factor is that the roundness of the two shafts is out of tolerance, the axial deformation of the circle is formed when the machine is not adjusted properly, the lead screw clearance of the shaft is not compensated properly, or the shaft positioning is offset, which may affect the accuracy of precision parts.
